We have a pool with ceramic tile at the waterline that is getting badly covered with hard water scale. How can we remove the stuff most efficiently? This page
says that you can use muriatic acid in a spray bottle to help clean it, but I don't want to be spraying undiluted acid at basically eye level! What dilution can you use to loosen the stuff, and do you want to let it set or scrub immediately? Also, what tool is best to use for scrubbing? That link mentioned a putty knife, in other places I've seen a pumice stone recommended. Any other tips would be very helpful.
