Thread: Cleaning of bore water stained windows

hydrochloric acid from the hardware store diluted in water. used to wash my underground ute with this, its the only thing that would get the brown stains off the glass and paintwork...

Hey Radz,

You could try "CLR clear" (Calicum, Lime and Rust remover).

You can get it from Bunnings. Never used it, but the adds look good.

Cheers

Thanks guys for the replies so far. Will drop down to Bunnings and give the CLR stuff a go for a start.

It might do the trick.

Cheers, Radz

Be careful of anything with hydrochloric acid as it will damage paintwork. The best I have found is silvo or even brasso and you can get it at woolworths. Watch the trim though can be hard to get off rubber and plastic. CLR is useless and does not live up to their adverts.

Go to Bunnings or your local trady type hardware and get a bottle of granulated Oxalic Acid. Mix according to the directions and put it in a garden spray bottle. Spray at low pressure then wash over with a sponge. Wait for it to disappear then rinse with a hose then wash with detegent to neutralize any acid.

DON'T USE HYDROCHLORIC!!!!


EVER!!!!!

Sent from my backyard TeePee using smoke signals.

Again my thanks for the time to pass on some tips guys.

No doubt there will be others with the same problems so will put up how I go.

Noted the remarks on hydrochloric acid.

Cheers

haha yeah hydrochloric is a bit extreme but works very well!! would bring up the filthiest brown stained landcruiser sparkling white and make the windows crystal clear... I never noticed any damage to the paintwork but I guess it was a bit hard to tell as they were covered in mud daily and stained brown again within a week... never buy an ex underground mining vehicle!!!!!

What most panel beaters use is a hydrofluoric based acid wash to clean mining vehicles. We have just had our fast attack done and brings it up a treat. You do need to know what you are doing as hydrofluoric acid if gotten onto the skin is absorbed into bone and basically destroys calcium and at this point if you are lucky will just lose the limb, if not well it saying hello to the worms. There are a few products around you can buy off the shelf, but get the msds and follow ppe directions to the letter and ensure every crevice is rinsed. I personally would also have a tube of Calcium Gluconate Gel on hand should you splash any on your skin.
Even these products do start to damage paint work and should not be used too often as it does peal away protective layers. Is very very good for cleaning aluminium.
Hydrochloric acid works to a certain degree in hydrochloric acid or hypochlorite solutions but does stain and damage paintwork. Have seen it many times.
