How Do You Acid-Wash A Swimming Pool?
If your swimming pool looks something like the “Black Lagoon,” an acid wash may be the only way to return its former gleam. An acid wash literally removes a layer of plaster from the walls, so it’s not something you should consider as part of your annual pool maintenance. However, if you can’t see the bottom of your pool or you are fighting continuous, persistent algae blooms, an acid wash may be your best option. Drain the water from your pool. While the water level drops, scoop out any leaves and debris and scrub the sides with your pool brush. Once the pool is empty, put on protective clothing, chemical goggles and rubber boots. You should also have a breathing mask to protect you from acid fumes. Mix one gallon of muriatic acid with one gallon of water in a pump sprayer or a garden watering can. Always add the acid to the water–never pour water into acid. Spray the pool walls with your garden hose and pour the acid/water mixture down the side of the pool. Wait about half a minute
