How to Clean Pool Plaster Dirt Stains
- 1). Tackle the dirt stain on your pool plaster with a pumice stone. Plaster is a tough material that can handle the use of a pumice stone when removing stains. Rub the pool's surface with the stone to "erase" the dirt stains.
- 2). Dilute the cleaner trisodium phosphate in water. You only need a small amount of trisodium phosphate to make a strong cleaning solution.
- 3). Scrub the pool plaster using a stiff brush. Again, plaster can handle quite a bit of abrasion.
- 4). Rinse the pool plaster, and examine the dirt stains. Repeat the process until the stains are gone.
