Do not hijack another's thread for info on your pool. Please, start a new thread as it causes confusion to the OP when discussing two pools in one thread. Casey~
I have an old pool (replastered 20 years ago) and the plaster is discolored, especially just under the tile under the coping. Does not feel different than the rest of the pool Does not brush off. Can be rubbed off (slowly) with a pumice stone. I tried a puck and a vitamin C tablet and neither did much. If a puck and vitamin C do not do it, what are the possibilities?
Thank you
Looks like either organic staining or metal staining. You can check in 2 ways. If it's organic, a puck will lift the stain. If it's metal, a Vit C tablet will lift it.
