As a professional landscaper I’ve had to clean some seriously stained patios in my time with lichen (black spots) being the toughest to remove since pressure washing alone might remove most of the stain but won’t kill the fungus so will grow back. What works best in my experience is sodium hypochlorite in the the 20litre drums you get from agricultural suppliers. Brush the patio first and dilute 1 part hypochlorite to 3 parts water in a watering can and use the watering can to cover the patio evenly. Leave for 5 mins then scrub over with a stiff yard brush and leave for another 10 to 15 mins and then pressure wash it off. If it’s a large patio or a hot day do 1 section each time it’s important to not let the diluted hypochlorite dry before pressure washing. After pressure washing rinse again with a hose pipe and flood any areas where the hypochlorite has run off onto grass. Be Carefull as it is strong stuff try not to breathe it in and it will bleach any clothing so wear old clothes and wellingtons. It also works well on the red fungus on roughcast walls using a sprayer. Also I’ve noticed that the hypochlorite once opened weakens over time so if you’ve got old stuff that’s been sitting in the shed for years it won’t work as well.
Used that stuff on my granite paving I used the recommended mix but it ruined the colour it was never the same
@@andrewholdsworth2198 I’ve never used it on granite myself only on Indian sandstone and concrete slabs. Can’t say I’ve ever come across a granite patio it’s not very common.
Thats basically a more convents bleach
I guess you'd need a seriously good mask for this; pressure washers put *so much* vapour into the air kicking up from the surface you're cleaning) that it'd be impossible not to breathe in a lot of that without a mask that worked to prevent vapour/moisture in the air surely?
Is there any alternative. Something not as toxic
I have had extensive experience of using patio cleaners and pressure washers on patios. My findings are that patio cleaners take 3-6 months to make a visual difference. But once they work they keep the patio clean for up to 2 years. So what I do is to use the pressure washer to bring the patio back to 'as new'. Then a watering to soak the now clean stones with patio cleaner. The patio then stays clean for a long time.
What about using a stone sealant on the stone?
I spray mine every 6 months never wash it, its like new, it works but takes time. Use pro-green now much cheaper and two options of dilution for dirty or just light soiling.
I agree, deep clean first (with either a pressure washer or good old fashion scrubbing brush) then spray with a patio cleaner/sealer. OK, a bit more work, but only needs to be done once a year.
Wet and forget has worked best for me. Spray in spring and then again in the autumn. Not an instant cleaner but give it time and be patient and the stuff works
Just bought this and a sprayer. Hopefully the fences will come up again
Been using Wet and Forget for years. Brilliant stuff but it does say that it doesn't remove dirt.
I know a friend who uses wet and forget on his roof tiles (bungalow) and it cleans all the moss and green right off within a few weeks. It looks like he's jet washed his roof
That rust stain at 11:20 can be removed by using fallout remover from any car accessory store. Its's the stuff you normally use to clean wheels etc (turns purple as it dissolves rust etc).
Nice, one ... tried all sorts of things to remove our rust stains from porcelain exterior tiles, even acid... Ciff or Jiff worked a little, however stains still there. Will try fallout remover now. Cheers!
So I've only used this pressure washer one time. th-cam.com/users/postUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP The one time I used it, it worked great. I recently had new siding installed but kept the old gutters and small areas surrounding my house that weren't replaced so they looked horrible and dirty because of the new siding. I needed to get it cleaned asap. When I used the pressure washer, man it just melted all the dirt and grime that was on those areas of my house. I used that krud kutter soap and it was over after that. Easy to assemble, feels durable, very simple to use. Also, I purchased a used one to save money and there was absolutely nothing wrong with it. I want to get more use out of it so I think I'll be washing the cars and update this comment as time goes on.
20 yrs I’ve cleaned many patios, block paving, roofs. If you’re jetting you know it blows out the kiln dried on block paving, a right mess. I just bought sodium hypochlorite for the first time, from Amazon, 15%, 10L tub. I wore shorts and t-shirt, gloves, shades and a baseball cap. I poured it neat onto pavers and brushed in, left it 20 mins and washed off (away from grass obviously) looks like new. No hassle, no hundreds of litres of water, no extra mess from jetting. I then poured it into an empty “Wet and forget” sniper tub, you attach hose to it and you can chose the driveway spray nozzle or the sniper jet to spray on roof, I soaked my lawn in water, sprayed roof, (rinsed my arms and legs as I went just incase any splash back) I then reloaded tub with some “wet and forget” and applied it afterwards. My neighbour had her roof done by those cash in the hand folks, hypo and jetted, looks good but very hard clean, but mines is just as clean but more natural looking, not strip bleached. Anyway I’m blabbing on, all il say is hypo is far quicker than jetting. Absolutely stress free. Just be extremely careful working with it. I had a few pink spots on T-shirt, zero skin burns, obviously diluted through the hose thing I used. Jetting takes hours and so much water it’s insane. Concrete slabs take longer than stone to jet. Look up “wet and forget” on Amazon, but the pink sniper tub stuff to attach hose to, once used, fill with hypo. Great for roof. Slabs I’d suggest 15% hypo, honestly 20 mins and you’re done. Wear PPE, especially on eyes.
I bloody love powerwashing the patio! It's like cheap therapy!
Agreed. I think its a power tool and man in control thing 😂😂
Or woman thing come to that.
Good, honest product comparison. Thank you. Back to the tried and true pressure washer system 👍
Great and much-needed test. I have a load of this stuff and I'm not surprised it doesn't work. Whatever it kills stays there and whatever can't be killed, stays there too.
I used patio magic on my render which had some green patches to clean it up before painting & was pleased with it, I think I went in with 2:1 & worked it in with a paint brush, but it didnt touch anything on my patio (even when worked in with a paint brush as I was using what was leftover from doing the walls) so I'm with you for using a pressure washer on that
I worked for a farmer who had a flag stone patio that was many years old but still looked like new.
He told me he used washing powder and just scrubbed it with a hard brush. I tried that and it worked a treat. It's also really good at getting oil off engines.
I used it on some garage fule pumps I once had to clean. Again. Looked like new and smelt nice on the forecourt 👍
And no harmful chemicals to worry about.
Also white vinager is great for getting stubborn stains off stones
Great tips, thanks. I think you need to avoid vinegar if your patio stones are made of limestone.
I find vinegar 30% only wotkd on weeds, for patio cleaning Sodium Hypoclorite does the job
Are you sure he was a farmer? I've never met one who cared about anything looking clean & tidy and if he did he'd use the most noxious, non-environmentally friendly chemical around .
@@garrywiseman2870 yeah retired farmer.
@@garrywiseman2870 Well you just haven't met the right farmers.
Yes Stuart, pressure washer all the time. I sometimes soak with just soapy water before pressure washing. Works all the time. Never found so called patio cleaners to work.
And of course using the pressure washer is therapeutic 😊😊
I find the chemical cleaner works over months and repeated applications every 6months keeps my drive looking great. Yes pressure washing is great but it blasts the pointing out and eventually takes the surface off mono blocks and slabs. I treated the tiles on my roof too and it looks brand new now.
Absolutely right. I used to jet blast, but that wrecked the pointing - and then penetrated under the slabs. Soon they were wobbling…. So an expensive re-laying and re-pointing followed after a few years. Since then I’ve used Wet-n-Forget a couple of times per year, and it’s fantastic. Great results, and can be used on walls and mildew/moss too.
Totally agree. We used to jet wash but haven’t done it for years. We spray when needed and it keeps it looking nice but with no need to brush sand in etc. I also find the weeds don’t come back in the way they used to after jet washing.
We have just tried a product called Proclean, Ultimate Black Spot Destroyer and it is extremely impressive. Sprayed it on with a similar sprayer to yours and immediately it starts to fizz. Within a few minutes the colour of the Indian sandstone slabs started to reappear. It says leave for between 2 and 4 hours an then hose off but I actually used a pressure washer with the fan nozzle we use for cleaning the cars. The results were amazing having thought we'd never seen the colours again like it was when first laid the slabs thats despite pressure washing the patio sometimes twice a year. Its not cheap at £42-00 for two 5 litre cans but well with it.
patio magic always takes few weeks to work for me including a couple of rainy days with amazing results jet wash is fine but if you use it on concrete slabs or paths it tends to erode surface after a couple of years not had any eroding from patio magic
I’ve been pressure washing for but this year I used patio cleaner put on with a yard brush left it for a couple of hours them pressure washed. The results were the best I’ve ever had!
Wet and forget is the best Stuart I use it each year it even works brilliant on my boat as well ie the canvas roof. Try it when you can. Great video as always
That stuff is Magic!
Thanks for this Stuart. I've long wondered if these chemical 'cleaners' are any good, but experience has suggested that anything that promises to be effortless is just snake oil! So I've just used the pressure washer instead. As you say, it's quite laborious work but the results are much quicker and more satisfying. For something that only needs doing once or twice a year, that's worth the effort imo. I also pre-wet the patio with the garden hose just to help lift the dirt a little beforehand.
ps. @15:18 the label on the Jeyes clearly shows that it is supposed to remove 'dirt', which one would assume makes the patio look cleaner too.
Great video Stuart and I, like yourself and everyone else, want a spray and walk away solution to my drive and patio, but a pressure washer is the only solution that works. The downsides are the amount of water it puts down in a large area, the messy splashback and clean up and the pointing it can remove. However, there is no alternative, the patio cleaners are so mild now compared to years ago that they just don’t enable them to clean the slabs/block paving.
Thanks for this Stuart, I appreciate your sense of humour, who thought patio cleaning could be so entertaining ! I don't think you were really surprised by the results of this test, people are still recommending chemicals and I can see they may help both before and after jet washing but they will not make it clean ! I don't know myself but could something like Thompson's water seal (or similar) help with very porous surfaces like your sandstone !
I think generally we worry too much about cleaning the surface completely, as long as there is no slippery algae and moss, the odd bit of lichen adds character and does no harm ! Jet washing is very satisfying though !
Pressure washer is best for cleaning. A few points some of which you may have made in the PW video. Need to take care you do not wash the grout out, wash across not along the grout. With pressure washers you need somewhere to swill (or manage) the dirt you have just released- especially for very dirty paving. Also there is a tendency to slash surrounding items with the dirtied water so rinsing them is also often needed. The "foam" that you washed off is probably the long term protection provided by the chemicals. Perhaps it is best to wash and then apply the chemicals. Then the troublesome areas should stay free of algae until the next clean is required.
We use ‘Wet and Forget’ which I think was the original of these types of products and it performs very well. The instructions on that state it needs rain after the initial 4 days to help it work. It’s ideal for older more fragile surfaces. It also states it can take months and not days to see the best results. Slow but sure 😊
I'm not from the UK so I'm not familiar with any of these, are these products basically disinfectants then?
Anything that claims to “take months” IS snake oil. Within that same time, the surface will have got dirtier - so it’s all just relying on the placebo effect.
Rain is something we get every day in the UK. 😂 @@csehszlovakze
Thanks for this!
I was hoping at the start that I hadn't wasted a Saturday, a couple of weeks ago, pressure washing a large area of paviors which hadn't been done for years and years.
I didn't! 🤣🤣
I have used both methods and several of the chemicals for years now and my preference is Patio Magic especial if used on concrete blocks.
Jet washing will clean but it won’t last any where as long and will increase the erosion of any grout or concrete.
The trick with patio magic is to put it on at a 4:1 ratio then leave it for at least a month. Then when it’s had some rain have a look at the difference between what you have jet washed and where the patio magic has been. It’s also excellent for cleaning algae etc off UPVC conservatory’s.
If you are going to jet was I would recommend using the T-racer attachment as it speeds the job up and help stop the dirt from going everywhere.
Do try patio magic again but have patience.
thank you for the logical, clear and fair analysis!
Hey Stuart. After using the pressure washer you can use a coating on the patio. This keeps the tiles longer clean. The coating is not cheap, but you don't have to pressure wash the patio every year.
I think this is basically a win for using the pressure washer a couple of times a year and less poisonous chemicals into the air/water table. Trying to minimise the number of chemicals used in my garden and be comfortable with 'less than perfection'!
Wet and Forget is brilliant. Rather than pressure washing 4-5 times a year, I now do it once at the beginning of Spring and at the end of October. After the Spring clean the patio stays clean of algae/moss for 6 months.
no good just chemicals but they do help but pressure washing is the only way
Totally agree! It's by far the best. It works gradually so you have to be patient. I've tried almost all the others and they are not a patch on W&F
Recommended wet and forget to a work colleague. Unfortunately, he couldn't quite remember the name when he tried to buy some. Apparently, wet and wild is not the same thing.
@@dirtyface091 it won't clean mud etc but nothing really will other than abrasion or pressure washer. Mud isn't really an issue for me, it's the greenery that's the problem and wet and forget sorts that out perfectly and keeps it looking good for ages. My neighbour recommended it to me, probably after getting annoyed with the pressure washer coming out all the time.
Why did the guy not try W&F?! Been using it for over 10 years & been very happy with it. Have not tried any of the products he poorly reviewed. He wanted them to fail didn’t he?! Pressure washers are bad news, making surface more porous & removing grout & sand in driveways. Hose & brush to remove dirt then W&F.
I've got the same pressure washer as you Stuart and I have the big round head accessory ideally suited to patios as you don't get spray going everywhere, it works really well and I think uses less water to boot!
Agreed. We've used 2 versions of the big round head accessory - had to buy the 2nd (a more basic model than the first) as the 1st wouldn't fit the new machine when we had to replace the pressure washer. They're far less messy to use although we still need the ordinary washer head to get into corners by walls. And then for some unknown reason, last time we tried to use it, that 2nd one had virtually no effect whatsoever. Water would come through and the jet bars turn, but it simply wasn't cleaning. So I tried to fit the original one again and, somehow, managed to get it on, albeit with the gun assembly at an angle. Much better!
We do have some chemical goop and I may finish that but it's unlikely I'll buy more.
Agreed too. I used to use the spiral lance thing and spent ages getting everything clean. The old pressure washer failed and I got a new one that came with a patio cleaner attachment (the big round one) and it's so much quicker. Yes, you have to revert back to the regular lance to get in the corners but it makes a huge difference.
It doesn't clean it as well as with the hose though.i used the round patio cleaner and if you go over the area again with a hose after using the patio attachment you will see it will clean it more
Oh dear Stuart, many of us have learned this lesson for ourselves. Just like you, I have Indian sandstone slabs which look fabulous when clean, and I noticed you have a number of slabs with the tell tale black spots indicating Lichen growth. A pressure washer alone cant eradicate this problem (sometimes it makes the problem worse). After some research online I followed advice that said to use SODIUM HYPERCHLORITE aka swimming pool cleaner which is essentially a strong bleach at 14%-19%. cleans the slabs a treat and removes all trace of algae and Lichen. I now follow this process annually in spring with a 'maintenance spray of a patio cleaner mid season for the best of both worlds. Hope this helps you and other followers.
This is the best way!
Yep, I just used 15% for the first time. I used it neat, brushed in, it foamed up white, waited 20 mins, rinsed off away from any grass or beds. Like new. To think of the hours I’ve spent jetting slabs for years. You’ve just got to take care using it and plan ahead. The internet has made purchasing the stuff really accessible, no idea where you’d have bought it 20 years ago. It’s absolutely hassle free. Is it for the most basic diy’er, mmh I don’t know, could be dangerous. Maybe for this channel it’s risky to promote a “pro” chemical.
what you described is absolutely the best way to do it. however, once clean, ordinary household beach will do the job. Its the same stuff, SH, but at 5% instead of 15....!
Totally agree. Used SH for first time this year on patio that had lots of black spot etc. Hard work brushing it all in but wow, was it worth it. Given what impact it had, likely may not need to do it again for a couple of years, so can just jet wash (with round patio head) dirt off in the meantime.
Hi Stuart, I use the pressure washer first, then apply an acid based chemical to kill off any mold/blackspots etc. I also do this treatment on my decking before oiling.
I've used spray and walk away. It's great for mould and lichen, but it can take weeks to work (like wet and forget, probably a better product), although algae disappears pretty quickly. It removed mould that pressure washing simply didn't touch. Also useful on tarmac, so you don't pressure wash the top surface into oblivion!
Another informative video. Thanks. I have always used the pressure washer and will be doing my patio again in a couple of weeks. I avoid chemicals whenever possible. You know what I have found works for clearing the algae - plain household vinegar. Just spray it on. A lot cheaper than chemical products. Add some dishwashing detergent and it's also great for cleaning just about anything else, shower tiles, glass, mirrors etc.
How refreshing to have a honest opinion.. We done thank you.. 👍
A great vid. Many thanks for testing. I've got a karcher 7 with the whirly nozzle, agree that it leaves spirals, I also find that it will remove masonry if you're not careful and is brutal on a tarmac drive!
It only leaves spirals when you don’t clean the stones properly.
Great video which has confirmed the way I do mine is perhaps best. Each late march/early April I presdure wash my patio, then after it dries I pour patio magic all over.
The pressure washing gets rid of the dirt and algae, the patio magic brightens the patio over time and helps to keep the algae from coming back for the rest of the year.
I only pressure wash once a year.
Without using the patio magic it's significantly harder to get the patio clean come april.
I've also found that aldi sell a patio magic equivalent for far cheaper which is just as good
A great experiment, well conducted. Thsnks!
Hi Stuart, well done again, another fascinating and very interesting, informative recording. I always thought a lot of these products are gimmicks and DO NOT DO exactly what they say on the box!! Please keep them coming. Cheers
I use Crikey Mikey. Spray on and leave for 24 hours then hose off. Works really well. My drive and patio area is very clean. Block paving. My drive hadn't been cleaned for about 5 years and my patio for about 3 years. It even kills the weeds between the blocks.
I wonder if these would be effective after a jetwash as a preventative measure. Next video suggestion; after a spray clean, spray some of the slabs with the chemicals and monitor if algae growth is delayed for longer. 😊
I've been through several cleaning options and my conclusions are: 1 instead of those expensive products just use bleach (same results but way cheaper). And 2, for deep clean patios, the pressure washer is best but I use an accessory (patio cleaner head) that covers a wider area making it a breeze in comparison to the normal pointing thing.
How are you applying the bleach on the patio? Like a pre-treatment via a watering can or maybe its better to fill a bottle of bleach and use the suction and pre-mix lance setting I was thinking.
Nice video. I use both as I don’t think it’s an either/or solution. Patio magic for 7 days to kill any algae, followed by pressure washer to clear the dirt.
I use a scrubbing brush, patio brush, elbow grease and collected water from washing up/showering. Looks great and gives me a workout too.
There's a lot to be said for elbow grease. I use a push mower and a scythe in my garden now and it's a lot less hassle than fuelling up and maintaining a petrol mower and strimmer. SO much more peaceful too!
@@-Pol-
Push mowers have a nice peaceful sound to them.
To be honest, I would rather use a pressure washer anyway, because it's not adding who knows what chemicals to the garden environment. Great review though, The results are pretty conclusive. my Concrete pathway needs a good clean, and I am planning to use a hard bristle yard brush and my son's energy, as I am now retired and just delegate- except when it comes to cooking the BBQ! which is where I am off to now with a beer! Cheers Stuart!
Thank you so much. With so many products on the market you always wonder which is the best to use -especially re the cost. Like you I found I needed to pressure wash first but then used the chemicals afterwards and half way through the year to prevent a shaded area turning green again.
Use smartseal extreme vry strong only brush and hose needed
I have tried most things and now I pressure wash then spray some sort of anti fungus the cheaper the better because next year I do it again again again again. I enjoyed your vid.
Hi. I have to agree that the chemicals on their own do not clean properly. I have found that they have to be used with a pressure washer to get the patio really clean. I have now switched to a rotating brush attachment to the pressure cleaner and this has reduced the time spent on cleaning the patio. Great video…I have learned so much from your videos…thanks so much
Rotating brush definitely speeds things up 👍🏼
Totally agree with your results...pressure washer is the way to CLEAN LIKE NEW. I use a Karcher K7 on my "light beige" ceramic patio tiles and it gets rid of all the green algae and ingrained dirt bringing them up like new. Another thing pressure washing does is get rid of any grass/weeds between patio slabs . Thumbs up for your video .
Thanks for saving me money, I thought what a great idea I have always used a pressure washer. Was a big disappointment when they still looked dull. I`ll stick with using the pressure washer and then spraying with a Path & Patio sealer which I find keeps it looking cleaner for longer...
Good video thanks. I have found the pressure washer method the best. I have used a chemical sealer which I would recommend. Just a spray on and leave it to dry. Made cleaning the slabs less often.
I recently did my driveway using the karcher specific cleaner in low pressure mode (no lance head and a Syphon tube) and then agitated with a combo of a broom and the t-racer... Finished off going downhill with a standard head... Couple of hours work granted.... But what a result
I use these twice a year over the winter period, just makes pressure washing in spring much easier as no deep levels of algae etc. The spray and walk away can be bought in pure form so you dilute yourself which is much better.
I was introduced to hypochlorite sodium last year and it immediately made years of dirt and weed residue lift from some stubborn slabs. Now use it in 5 or 6 to 1 as a general weed killer for the drive and patio on very dry days.
Informative, authorative, balanced and well delivered with a rye sense of humour.
Great viewing.
As you say, for the best results use the algae remover and then blas it with the Karcher!
Glad to see I have been doing it right. I would recommend using a cheap mould spray from a £1 shop/ Home Bargains as a quick fix on a small area. Our back door step gets a little green and slippy over winter. Rather than get the pressure washer set up a few seconds with the spray kills off the slime.
Great video, watched a couple of your vids very well shot informative thanks 👍🏻
Cheers Stuart. I used patio magic and was underwhelmed. I use diluted bleach and a hard broom. Leave for 20 mins and rinse. Works a treat on my Indian sandstone but quite hard work.
Great video again mate and exactly what i was after! Been wondering whether to get Patio Magic for years, but your video has certainly changed my mind! I'll stick to the pressure washer. Great content as always - keep it up!!
Patio magic is brilliant
Totally agree you can’t beat using a pressure washer for that newly laid look again, although the only down side I have found is that each time you do this it must remove some martial & I found the algae had an easier time of growing back!
The chemicals likely help prevent it coming back. There's probably a less dangerous chemical you can use to do the same thing.
@@TheLukemcdaniel bleach.
Hi Stuart. Totally agree. Pressure washer is the best.
What people do is apply algae, lichen and moss removal chemical and then, after a few days, pressure wash to remove dirt.
Ok, Wet & Forget is another product that I believe should have been thrown into the mix. Yes it needs diluting & probably does exactly the same as the other products, but I tend to jet wash first, then apply the product after it has dried. Seems to last quite well.
I use. KArcher pressure washer with the patio cleaning tool. Use the detergent and my patio looks great. My main issue is Saharan sand dust on the patio which kind of bakes on during the summer. The pressure washer does the job
I'm trying a product from New Zealand called Wet and Forget. It's about £35 for 5l which you dilute 4:1. It says the product carries on working for 12 months. Here's hoping 😁
How have you found the Wet and Forget over the last few months ☺️
I love Wet and Forget. It kills algae very quickly then the weather gradually gets rid of the dead algae. If it’s good enough to clean Sydney Opera House it’s good enough for me. 😊
Hi sir I agree your method is definitely the best , especially when you have grass adjacent to the patio . And as you showed you need a mechanical action to physical push the dirt off the surface . There must be hundreds of people who buy these products , and think they will wake up to a new looking patio only to be sadly disappointed . Best wishes as always. 😀👍👍👍
Hi .. I’m a hard landscaper as well as a patio cleaner … for sandstone to be cleaned and stay clean , I find that when you pressure wash the slabs , that’s the best clean you’ll get .. the other thing to do to keep them clean is to spray a product called BAC 50 Diluted 20 parts water 1 part chemical every 6 months .. usually does the job … one thing I will mention .. I notice you have weeds growing out of your patio joints … the best advice I can give you would to use ultrascape free flow slurry grout .. absolute solid …
BAC 50 is Benzalconium Chloride - works a treat - I found 10ml to 1 litre of water worked fine.
Hi Stuart , I just use soapy water I use Fairy liquid or Star drops and a jet washer ,it dose the job But thanks for the video I know it cost you for these cleaning products but some time stick to what you know As always great video I do enjoy watching , see you on the next one take care mate
Patio magic worked for me. Diluted it in a watering can, gently applied and brushed in with a garden brush. Took 24 hours and all green was gone. Our slabs are quite new so maybe with age the dirt becomes more engrained.
I use a mixture of water and bleach - approx 65/35 (more bleach than water). Works a treat and is MUCH cheaper than any 'dedicated' expensive stuff saying "Patio Cleaner" on the label 😮
Just cleaned my patio, tried the patio head cleaner with the jet washer which was fine to start but then it stopped turning round so just used the normal nozzle, worked well. With pets and lots of wildlife in the garden I’d never use chemicals.
When the nozzle stops spinning it's (in my experience at least...) because sandy bits of the stone or concrete surface have splashed-up and added friction to where the spinning part meets the base of the patio cleaning head..
With a Karcher there are steel C-clips above the join that you can pull out with needlenose pliers or pry out with a screwdriver and seperate the spinning part from the arm on which it is mounted by pulling it downwards, then just rinse the sand/grit/gunk out with water and an old toothbrush and reassemble everything, and it works like it did the first day I had it.
I now do this after I finish cleaning the patio and it takes
Really enjoy and appreciate all your helpful videos. You are a fountain of great information, and a terrific presenter. So here's one for you: please do yourself a huge favor and get a surface cleaner attachment for your pressure washer. You'll be amazed at how well they work and all the time they save. A real joy to operate, and not very expensive. Best regards!!
I’ve used Patio Magic for the last 5 years and have always been happy. No quick fix but over the weeks, I think it reacts with the sun and does come good in the end.
Absolutely agree. I wouldn't use anything else. It seems to get better as time goes on and then the next year it's not nearly as bad. Can't understand why people don't rate it. Not needed to pressure wash my patio for the last 3 years.
I have as well over the weeks and months it gets better and better my patio looks great and the colour has come back into it
Patio Magic is really good, been using it for a few years now, it lasts about two years 🇬🇧
Thanks so much for posting this. I have the same patio (kandla grey Indian sandstone) and I have been planning to do the patio with a patio cleaner as with a pressure washer on its own doesn't seem to do the job. So, I'll be buying the patio magic and giving it a go, looking forward to the results. Thanks again 👍
Here in Cornwall we still have an hosepipe ban so no chance of pressure washing! I successfully used a competing product from Spear and Jackson to remove algae from decking, wood cladding and patio. But that’s all it does - I agree that cleaning beyond that is minimal.
My patio is the local “High Street” for about 5 neighbourhood cats so I rather think chemicals are not suitable. Fortunately our problem seems to be moss rather than mold, but it is going to be so satisfying to get it cleaned up! Thanks, though for taking one for the team on this dilemma.
I just used the "karcher k5" with the "dirt blaster lance" with the "karcher splash guard" and job done in one go, No chemicals, no extra costs, no splashed up dirt everywhere, no wet clothes! 🤷🏻♂️
Looks like the best thing to do would be to use the cleaner after the tiles dry from pressure washing to kill the remaining algae and prevent/slow future growth.

ProKleen is the best I’ve used (on Indian Sandstone) even vs pressure washing - we tend to get a lot of green algae build up rather than pure “dirt” though
Useful video. Wellies and waterproof trousers are a must though of doing a large are otherwise your bottom half gets soaked after an hour or so. Canary suits or cycling trousers are cheap enough.
Thanks for the video, much appreciated for your time.
Like some of the comments... I use sodium hyperchlorate... diluted... we get a large drum of it from our pool supply company and then dilute to about 10:1. We apply it and you see the results very quickly...within minutes and it keeps working. Need to use protective shoes, gloves, eye protectors and best with a face mask too. We get brilliant results compared to your three tested products... as we have a vast amount of sandstone patios it is much more efficient to spray vs jet wash. Another upside is I find the pointing is not damaged compared to when we used to jet wash...
Great video. I do both. Power wash to get the dirt off and then I use Wet and Forget from Costco to prevent the green coming back.. It is an American product and it definitely stops the green coming back for up to 6 months.. I had some black spots that the power washer wouldn't remove but the wet and forget did after 3 applications.
Many thanks for your videos - style and content. Glad you did this as I was thinking of trying one of these products.
Have you also thought about testing Black Spot removal stuff? Prices vary so much.
Good vid. I use the No Nonsense solution from Screwfix. Great stuff. Dilute it, apply from a bucket with a brush and give it all a good scrub, then go over with the hose or pressure washer. I do this for my porcelain patio and it comes up really well but would also be good on stone slabs I think.
I think ????? 👀
I have always just pressured washed. This year however after pressuring washing I used Freescale Black Spot Remover. As I expected it really only faded the black spots. However, I was stunned by how much better the patio looked than pressure washing alone. This will be my method every year from now on. Pressure wash as normal first and then use the product afterward. (edit: I should add, this product is some strong bleach-based system, not only the PPE but if you get it on clothes then they'll look like some 1970s tie-dye hippy crap)
for maintenance, household bleach is cheaper and just as effective. (its the same thing - sodium hypochlorate)
There are numerous TH-cam videos that show how commerial grade 15% Sodium Hypochlorite is extremely effective if used carefully with the eight PPE.
I've tried thick bleach used 50/50 with dishwashing detergent (as demonstrated on TH-cam) to be effective along with brushing to vastly reduce the pesky black mould spots.
I’ve used the Wet and Forget product for a few years now. Brush the patio with a stiff brush then spray the surface with 1 part chemical to 4 parts water in January time. Find the weather helps to get the chemical to work and by early spring the patio is lovely and clean. I don’t reckon you’ve allowed the chemicals long enough to work
Tried the Patio Magic on concrete tiles. It did help and appeared to keep it clear longer when compared to a section where I used diluted bleach.
top tip - dont dilute the bleach. Its already at only 5% concentration!
I wish you’d published your video two weeks before you did, Stuart!😊
Then I could’ve saved the 15 quid I spent on PatioMagic.
Like you, I followed the instructions to get the mix right and waited for the right conditions and sprayed 3 test slabs.
Over a week later there was no discernible difference between the treated and untreated slabs.
So, I got the pressure washer out and now I have a bright and clean looking patio.
FYI and IMO - pressure washing is so much more satisfying than spraying chemicals.
I no longer use a pressure washer and use Wet and Forget instead. It gets rid of algae/green quite quickly but requires longer to clean the slabs in combination with rain. It then keeps the slabs algae free for up to 18 months i find. Ground in dirt does need a PW though.
Just done mine, used both.
We use Patio Magic,and have found it very good. Gets rid of the algea, easy,twice a year,great stuff.
Brilliant review, thanks very much
I'm a professional patio cleaner and i call myself Pat.E. O'Cleanagh which works well for business here in Ireland !
I use the Patio Magic on the picket fence around our holiday caravan after the worst of the winter to get rid of the green mess that accumulares and found it quite good. That might be because they are vertical and we may have had some rain a day or so after application which may have washed away the green mess.
These are a good pre treatment to a pressure wash. Applied a few days before hand, they help to lift any grime and make the pressure washing easier and quicker.
I still prefer the pressure washer method ( just clean water, no additives ), I don’t want any chemicals whatsoever in my garden, I’ve always thought that these cleaning products are cash cows and not garden /wildlife friendly ( soil has a micro eco system and any man made chemical will upset the natural balance ) . Besides, in the garden a few natural blemishes are beneficial in my opinion, an established garden shouldn’t look man made perfect. I like a bit of moss algae lichen for that natural established look on brickwork concrete etc . Great video as always Stuart 👍
Hi Stuart, I would never of doubted the power of the jet washer, but would you use any of the cleaners as a preventative for the algae after jet washing? Cheers 👍
Informative video - cheers for this!👍
Very useful - you have just saved me a few quid! I have several sections of herringbone brickwork (one is 80x15 ft!) and I guess a re-mortgage might have been in order. I'll stick to the pressure washer and a couple of days off work instead eh?!
I think the chemicals just kill off the algae and such. I used something similar on my crappy old wooden deck that had turned green and stank of algae in the parts that routinely see shade; it killed off everything and left a grayish surface on the wood, which was the dead algae. It obviously can't just vanish - just die and dry up. Next step is still going to be the pressure washer (carefully) and then breaking out the Wagner sprayer and painting the whole shebang white. But yeah, on stone like this - a patio washer that attaches to the pressure washer is no doubt the way to go. Those have jets of water (and maybe brushes, don't have one tbh, due to no stone patio) that scrub the stone while washing. Solid investment I think if you have a stone patio. Oh - and it might just be an idea to first clean the stone with a patio cleaner attachment or just the pressure washer, and then spray a layer of your chosen product. It should form a surface that makes it much harder for the algae to come creeping back, as a preventative measure.
We have an absolutely massive stone patio in Wales that gets green as hell every year, just taken me 2 weeks of 3 hours a day to get it clean with a k5 karcher pressure washer. What I can say is we used the patio magic through the winter period a couple of years ago and it hugely reduced the green we had the next spring, all we were doing was washing the dirt off then which was a lot quicker.
We didn't use it this winter, and I really wish we had now.
