Thread: Muriatic Acid Stained Pool Deck

    Muriatic Acid Stained Pool Deck

    Had a leaky bucket when I put acid in my pool and unfortunately spilled some acid on deck of the pool.
    Is it permanently stained, or is there something that will cut the acid and bring back the natural color of the cement.

    My deck's natural color is a light rose/tan type of color - where the acid spilled darkened it.

    Acid doesn't stain, it eats. Time might bring it back closer, but it's not going to scrub off. By natural color, do you mean the concrete itself is colored or is it a coating? If the color is in the concrete, pressure washing "might" help, or even acid washing the whole deck, but I wouldn't try it without having a concrete pro have a look.

    Yes, the color is in the concrete and not from any paint or stain.

    I may try some power washing. It's tough to do because it's so close to the pool.

    You sure it didn't etch your deck?
