Hi. I have areas of my plaster pool that have calcium deposits on it. Nothing serious, but little tiny pebbles (maybe the size of a pinhead or maybe slightly larger).
I tried the wire brush that I got with the pool, but that does not do anything. I bought pumice stones online, but maybe I bought the wrong ones, but they seem to disintegrate in the water as I am scrubbing (is that normal)?
What other type of stone can I use to get the calcium off but will not harm the plaster? Thanks
