First time pool owner, and love the site! i have followed this site to the tee and everything has been perfect, minus yesterday when I tried to clean off the white stains from my tiles with MA as my PB suggested, and now my plaster is stained terribly. It appears that some of the tile grout was dissolved by the acid, and has fallen to the bottom and sides of the pool. We just went to vacuum it up to find that it has stained all the plaster!! there are some large dark brown stains, but thousands of tiny little stains in the texture of the plaster. It looks like sand was dumped all over the place.

taylor 2005 kit, 18k white plaster with blue quartz 30%.
I tried vacuum, brushing, brushing under water with a hand brush, all with no effect. Is there anything I can do to remedy this? So frustrated!!
