HA! I have the EXACT same faucet, but I cut that obnoxious spray nozzle "keeper/holder" off. I use a stainless steel spring to keep the sprayer out of the way, but it easily stretches so you can use it and It retracts out of the way after use.
I have a chrome chair i want to clean. It's a bertoia diamond chair, so the shape is an interwoven pattern. Do you have a suggestion on how to immerse something as big as a chair?
Caustic generally refers to alkalis like sodium hydroxide (caustic soda). Acids can be be very strong depending on what context you measure strength. A pH zero acid on the 0 to 14 scale would be one mole (molecular weight in grams) of say sulphuric acid, in a litre of water. For sheer destructive power, oleum is hard to beat. Additional Sulphur trioxide dissolved in concentrated sulphuric acid will suck the water out of flesh. A fearsome acid is Hydrofluoric acid that will dissolve glass, and Aqua Regia, a mix of Nitric and Hydrochloric acid, will dissolve noble metals like gold. The hydroxides of alkali metals like Lithium, Sodium and Potassium can all hit pH 14 and will dissolve a lot of metals, zinc and aluminium for example. Get them on skin and very quickly the oils and fats in your skin are converted to soap.
What is Ideal depends, there is enough water to dissolve all the ocalic acid added, so the difference here is the relative strength of the acid. You can easily get away with adding less, but it will take longer. Time is money :) If faster is worth the cost of wastage, then using 'too much' is better.
I've recently ran into some trouble with a failed caliper, and although everything is bow squared away I'm left with a rim thats covered in a layer of rotor shavings that have rusted. Would this be safe to use to remove the flakes from my rim without damaging the finish?
Just rinse off your hands afterward. The powder isn't bad, and won't burn you unless you just leave it on your hands for a long time. I don't think its considered a carcinogenic either, so you should be fine unless you have super sensitive hands. I have used floor degreaser that was FAR worse, and handled with much less care than this.
Oxalic acid is a weak organic acid, like acetic, tartaric acids. In it's powder state, it pretty harmless - don't eat it or sprinkle on your cornflakes - but when in solution, that's when it's acidic. It's not in the same league as sulphuric, nitric, hydrochloric or phosphoric for dangers. Caustic soda, sodium hydroxide, is a powerful alkali, again relatively safe when dry powder, but lethal when in solution. Sulphamic acid is the strongest solid acid. Oxalic acid works by dissolving the iron oxide and converting it to ferric oxalate. My preferred rust remover is dilute ortho-phosphoric acid with a dash of propanol as a wetting agent. The advantage of phosphoric is that the resulting ferric phosphate acts as a surface protection against further oxidation and can make mild steel go black finish.
@@philipslater5015 That's interesting. I know oxalic acid preferentially attacks iron oxide rather than raw iron, but if you let it go too long, it will indeed attack the iron as well.
Oxalic acid (solid) is becoming hard to source (UK) due to changes in legislation. Reputable chemical supply houses won't sell solid 99.9% oxalic acid to individuals, and will only sell 9.99% solutions as anything more than 10% has to be restricted to licenced individuals or companies. Something else on the banned list.
I have done citric acid bath for frame many times, chrome or painted, now I have set of Ukai steel rims, it has gold color chrome or (Anodizing) on it, would this method damage the gold color?? thank you

Glad I could help.
Nicely done!! I use this method every other day for bicycle parts! Best way in my opinion! Cheers
Awesome....I will use this method to restore a '61 Huffy Eldorado bicycle that belonged to my Daddy. Thanks very much for the demo and info.
Nice clip. cheers! You mention waxing when you're done. Using what?
Very nice work! I'll be trying a similar process on the inside of a motorcycle fuel tank.
Hi, I have set of Ukai steel rims, it has gold color chrome or Ano on it, would this method damage the gold color?? thank you
How do you dispose of the liquid? Can't be safe just down the drain right?

Well if that isn't a pleasant tune in the background. Great tip on cleaning chrome!

what will happen if we directly apply oxalic acid powder directly on the rusty area and rub it?.Is the powder cause harm to human body ?
Yes... th-cam.com/video/6Ux6JSyoOJs/w-d-xo.html
get it re-chromed or sandblast and powder coat it! there are a lot of processes that you can set up at home that are not too difficult to learn

I notice that you have a black sink; is this acid safe to use in this type of sink?
Way too much Oxalic acid is being used and therefore wasted. For that size tub you mention (1 liter), you could get by with a few tablespoons of OA.

It's also better to use HOT water.

Great video thanks! Music high spikes were killing me

can I use oxalic acid on my CPU heatsink? I think its made up of aluminum its Noctua NH-D14
I'd like to say it would be fine but I cant be positive. If in doubt, don't risk it.
tried it but it didn't remove the stain :(
