How Do You Remove The White Stains From Swimming Pool Tile?
Over time, calcium deposits will slowly build up on the tiles that line your pool, turning them white. This is usually caused by filling your pool with hard water (which has calcium dissolved in it), but it can also happen when rainwater runoff that enters your pool carries calcium from the soil with it.
Regularly removing this calcium buildup from your pool tile is important. It improves the appearance of your pool, and it also prevents large deposits from blocking your pool filter.
