Pb Plans To Use Muratic Acid To Clean Exposed Liner

[Waterworks]

We have a product for cleaning the waterline of pool liners called GrimeAway. It is sulfuric acid, hydrocloric acid and phosphoric acid I think. Even still, while I sell that product, I normally recommend baking soda or vinegar to clean most pools. I don't make any money this way, but it seems to work better for the customer, so what the hell.

I stopped PB from using acid on liner. But he wants to clean the fiberglass steps with it. Should I stop him? He has already cleaned the concrete that splattered on the outside edge of the steps, and it (cleaning agent) left white spots on the concrete deck where the cleaner(acid?) dripped. He does not want to wash the concrete deck with muratic acid, (says it will ruin concrete) but wants to use acid to clean the steps on the inside of the pool. Is something strange here?

Can the concrete be acid washed? If so, how? Would the coping and steps and so forth need to be taped off, so the mixture would not damage them? Thanks again.

It's OK to use muriatic acid on the steps. We've done that with no problems, and it cleans them great.

PB says that he used water and rag only to clean the excess splattered concrete off the deck side of the steps and spa. However, I find that hard to believe, because there are white areas on the concrete deck that look kind of like they are bleached out or whiten by whatever dripped on it. He claims that water dripping on the concrete, within the first 8 hours of a fresh pour, will leave white areas. As a result, I have white spots all the way around the steps and spa where they are set in concrete deck. If what he says is true, I wish he would have let water drip on the entire deck, because it would have removed the red stains. I can understand that water would affect the finish, but to make it look so white I find hard to believe. Does anyone know if what he is claiming is true?
