Correct solution for acid washing

[eemueller]

What would be the correct percentage of muriatic acid to water for acid washing my pebble sheen pool? Thanks.

I can't help you with that, but perhaps if you explained why you need to do it you might get a more detailed answer. And of course any pics showing the problems! We love pics!

I know a lot of people that will use straight Muriatic acid and just leave the hose running so you can rinse it quickly. After a few minutes you'll get an idea of how long it needs to sit on the surface before you rinse. If it's a newer pool surface then I'd try a 50/50 mixture just to limit the damage.
