Acid wash concrete deck

[MJuric]

We have an in ground pool with liner. The concrete is rather stained, algae etc. I did a test area where I used muraitic acid and a wire brush and it looks shiney and new. However I'm concerned about getting the acid on the metal portion that holds the top of the liner. It looks like painted aluminium and I'm guessing the acid would damage it. Is there a good way to protect this part of the pool when I'm cleaning the deck?

Thanks

Not a good idea. Acid will damage the deck. I recommend a pressure washer or apply bleach and allow it to thoroughly dry before rinsing it off. Don't get bleach on the aluminum.

In what way? Every stain and dye I've looked at recommends to etch the deck prior to staining. You use muraitic acid for etching.

Acid eats up cement. You're going to eat up the cement and leave exposed aggregate, which will be horrible to walk on.

The guy who did my deck told me to use simple green mixed 1 part SG to 2 parts water. Then use a lite pressure washer mainly to wash the Simple green off.
