Also called a drain & clean, an acid wash may become necessary if the pool hasn’t been used for some time and algae has taken over. If you notice creatures splashing around out back or foliage that you didn’t plant, it’s probably time to drain & clean.
Our general rule of thumb for determining whether or not to drain and clean the pool is whether or not you can see the bottom of the pool. If you can see the bottom of the pool (the floor) then you can bring it back to life with chemicals, labor and filtering. If the floor is not visible, the cost of the chemicals and labor will generally be greater than the acid wash charge, and take much, much longer. Also, if you have an extensive amount of algae blooms, it will stain plastered pools, making an acid wash preferable.
An acid wash is, put simply, stripping away a layer of plaster, exposing the fresh plaster beneath. Therefore, we do not recommend making this an annual tradition as it will accelerate the need for re-plastering. Most plaster coats (sometimes called whitecoat or marcite) are more than a 1/2″, so a few select acid washes should not hurt.
You may also decide on an acid wash not because of swamp conditions, but just to bring out a brighter, whiter finish. If your pool suffers from mineral stains and/or deposits, chlorine stains, even dirt stains…an acid wash is a dramatic aesthetic improvement.
If your pool has had years of algae blooms, and if your pool seems to grow algae with little to no effort, changing the water and acid washing the surfaces that algae attaches to can give you an algae free summer.
Acid is a dangerous substance. Our personnel are specially trained in its application and wear protective clothing and breathing apparatus during the acid wash. To protect our environment, the acid/water waste is always neutralized prior to its being pumped to a safe location.
