pH Balanced Pool Service offers tile cleaning and acid washing for your swimming pool . The offseason (October – April) in Arizona is the time of year when you can remove the eyesore of calcium buildup/scaling along the waterline of your tile. We will take care of the draining, tile cleaning, and startup chemicals. We also offer an acid wash process that will clean up surface staining. If your pool hasn’t been drained for a couple of years, then it’s highly likely that a tile cleaning and acid wash is just what your pool needs to look beautiful going into the next swim season!
