Good to have you back hope you had a nice break.See your back on the soft washing as you have said in the past you had a bad experience and stoped doing it. Any chance you can give us all a good look at your softwash set up? If you want to keep it a secret fair play. Great channel keep it up! M
Hey Matt, this is a vintage video from 2016 that I came across on my laptop having a clear up this morning. I don't do roofs and such anymore as too busy on the windows. If you look at the conservatory cleaning video that shows the machine used for this job. Cheers.
Green Pro Clean Ltd what a shame its an oldie! Seen the video your talking about which was great but left me wanting more of an in depth look of the total set up. To many over complicated set ups on you tube. Any information you can give on this subject would gratefully be appreciated. Can you give us a link to the machine you used as im struggling. Cheers M
matthew calder same same any info on your set up would be great! I currently use window cleaning equipment to apply softwash........ not ideal. Also you say you use algo but have you tried using hypo mixing up yourself to the correct strengths for different jobs? Thanks in advance
Adam Gregory I have been asking Darren to give us more of a an in depth look at his soft set up but he says he doent do it any more as busy with the windows. I have asked for a link to the machine/ set up he used but never replied. Such a shame because he is such a good teacher and normally very helpfull but for some reason he shys away from the subject now. Think he had a bad experience with hypo so dosent want to share the knowledge. "Soz darren all said with respect mate" M
Excellent commentary on your method and setup. Thank you.
What was the time scale between the "before" and "after" at 3:04 and 3:05 ?
Many thanks.
About 30 minutes
Roof cleaning contractors who use sodium hypochlorite (chlorine bleach) mix it in high concentrations with other chemicals such as trisodium phosphate, also known as TSP.
They spray it on the roof and wait for it to dry and then re-apply it several times as needed. Stains and moss or lichens that don’t come off on the day of treatment may eventually come off with rain in the months to come.
Pros: The bleach method can be less expensive than other methods because the chemicals are inexpensive and the technicians generally don’t get on the roof to rinse or inspect after the application.
Cons: Strong chemical odor and results that may not be instant, particularly when moss and lichen colonies are involved. There is also a possibility of posing harm to people and pets if exposed to the fumes or fluids. The effects of bleach on landscaping can cause permanent damage to plants, trees, grass and shrubs. Contaminating bleach and phosphates can leak into waterways in watershed areas.
Tip: Roof cleaning contractors who use chlorine-bleach typically don’t advertise or divulge that they use bleach. If they need to wet down plants before, during, or after treatment or use a runoff recovery system or cover plants during the roof cleaning process, these are indicators that a harsh chemical such as chlorine bleach is being used
Some good info there Ash. We use a lot of SH in roof cleans, diluted to 2.5% strength, lower than most household bleaches. We also then add a surfactant, basically soap to help the SH 'cling' to the surface better.
We let all clients know EXACTLY what we're doing and how and so far no complaints.
The only secret to using any types of chemicals to clean any surface is to do so responsibly.
@@Darren-Green this is the thing if I was even to touch a roof I'd need to do a course or something along them lines even when cleaning gutters etc is rather take more time scrubbing than using chemicals 😅🤣🤣
@@ashjohnson8099 A tip for gutters is use Ubik 2000 - excellent on UPVc and pretty harmless to plants and animal life.
@@Darren-Green I've been told if you don't mix properly it'll turn plastic pink etc and could male the plastic run and betime you apply Chemicals you've already scrubbed
@@ashjohnson8099 you have been informed wrong sir. Ubik does not stain UPVc
Interesting debate mate on pressure washing tiles....hear so many different stories....couple of questions mate i assume you are applying SH....what mix do you use mate?....do you leave it on for like 20 mins then wash off...then apply a biocide? Where did you get your pole and softwash system? Thanks mate
Many customers just want clean. I found when offering biocides they have a sense that it's not worth it as it took 10 years for the roof to get that way to start with. But yes, SH at around 2.5% for 20 or 30 min tea break.
Hi love the vid, notice the solar pannels on roof , would sodium hypochlorite harm or effect the solar pannels in anyway , or would clean them too if they had moss on them ,
Clean them off too, no point to do half a job - as long as you rinse thoroughly there should be no harm to the panels
love your videos i watch them all
and im not in the cleaning game i like to do my owen dits after a week in the office
love your tip
im going to do my roof next week the hipo i get is 10per cent would i go 25 litres of hipo 25 litres of waters
or raw any help please would be recommended
I would start a 3 parts water to 1 part hypo 2.5% and use a few coats instead of trying to do it in one pass.
Great job
Great job 👍🏻
I have tried to do my roof today. I had no surfactant so used baby shampoo. I climbed up on to the roof using a cat ladder. I used a garden 5 l spray bottle. What type of surfactant do you use please ? What do you use to mask the smell. I was nervous about the over spray going on neighbours cars ? I asked them to move them. Would it damage the paintwork on the cars if oit did ho on them ? Thanks forcyour informative videos. Stay safe.
Thanks again
Hi mate , nice work.
Iv just started soft washing roofs,
may I ask what the name is of the protective surface coating you apply ?
Aslo what strength of SH did you use on this roof ?
Cheers.
Hi, thanks for the video. Have u ever tried taking the paint off an exterior wall with SH?
No logical reason that would work after all sodium hypochlorite is an ingredient used in bleach it's not a paint stripper.
@@Darren-Green Thanks for your reply. Loads of people don't bother
Very helpful thankyou
Hi,
I have been watching your video and want to clean my concrete roof. I was wondering what products you use to do the clean and can you help me out.
Thanks gary
Hi sir can you please tell me what amount of SH need for that 3 bed house. Thanks Roland
What bar of pressure you using mate
Most important is chemical and it's strength, Please me what chemical you used.
What was the magic coating?
Mostly a mix of SH and Fairy for stickiness
Do you still carry out this roof cleaning service as I can’t see it on your website
No mate as I now live in the Philippines
Did you deal with the lead flash round the chimney ?
No Scott, On all the jobs I have done I have noted that within around 10 days the flashing returns to a normal dull gray lead color from the brown caused by hypo so I do not bother -
@@Darren-Green sorry to say I haven't experienced this......
@@Darren-Green dint agree with that at all hypo can discolour the led flashing and should be either covered or kept wet or if it is discoloured still led x pro takes it back to its original state
Can you tell me what chemical you use please
read the words below the video geeez
So you rinse after the S.H treatments?
How long do you wait to rinse? After SH TREATMENT?
About 20 or 30 mins by then the SH isn't active anymore
What mix rate of sodium hypochlorite 15% do you use to get this result?
What I used on that day in those conditions is not relevant unless you are doing exactly the same job in exactly the same conditions - ever job is unique - start around 20 - 1 for light soiling and increase strength from there as required
Green Pro Clean Ltd brill, thank you for the info. Great video.👍
What equipment do you use to apply the cleaning agent?
An electric softwash machine - try Ben at Rutland Pumps
How long would that take roughly?
I allow 2 days for most roof cleans to do them properly -- your question is the classic how long is a piece of string - you have to allow for temperature, how dirty the roof and other factors --
Where can I buy your nozzle sprayer please?
Pressure tek website
What kind of nozzle are you using?
A custom made one
Interested on the pump you've used to apply the hypo. And where it can be gotten I power wash houses but looking at soft wash options
Talk to Ben at Rutland Pumps
👍👍👍
A job well done😅👍
Thank you.
How do you mix the solution and water and spray it without a soft wash system?
How do you make scrambled eggs and bacon without any eggs and bacon?
Ricky use a backpack. Mix it yourself and use a pump action back pack mate. You don’t have to buy a soft wash system.
@@theyoungottoman2678 thanks 👍
Ricky Singh I do pressure washing and soft washing myself. That doesn’t mean that I would withhold information for people who look for alternatives! Good luck veera! 🙏🏾 wahe guru
@@theyoungottoman2678 thank you, appreciate the suggestion and a nice response to a question. I did think about a backpack sprayer with weedkiller in, but Ive got to get a better shoulder strap for mine as it keeps coming off. On a smaller section of a roof I did try using patio magic solution as it's ment to get rid of moss. Used a watering can but didn't clear the moss away. Never went back to trying anything else. Will try it with a better moss killer solution. Thanks again veera, wjkk wjkf 🙏
Can you leave the solution on.
What is the name of the chemical Lance mate cheers
It's called Sodium hypochlorite
@@guts0113 what mix was it?
otherwise known as "bleach" (Sodium hypochlorite - yes really look it up!)
Are you using hypo for this?
Yes, in part
@Darren found it lol
Good Job
Great job
Thank you
