WHAT IS AN ACID WASH?

Acid Washing is done by emptying the pool and spraying it with a small, diluted amount of special acid. This acid will remove a thin layer of pool plaster and the mineral buildup that is coating the top of the plaster to reveal a bright, new layer of plaster underneath. This process is quite safe when done by an experienced professional swimming pool technician but the process can be very destructive to your pool if completed incorrectly.

Make sure that whoever you choose to acid wash your pool knows what they are doing. The most common problem that inexperienced pool technicians have is over acid washing your pool and spa. This occurs when the technician either leaves the acid on the pool walls to long, the weather it too hot or they use too strong a concentration of acid. The result of over acid washing can be as small as an undesired color in the plaster or pebble-tec or it can be as severe as flaking or chipping plaster which is noticeable a week or two after you have refilled your swimming pool.
