Pb Plans To Use Muratic Acid To Clean Exposed Liner

[doggie]

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?
