The process of removing a thin layer of plaster or pebble finish from a swimming pool using a diluted muriatic acid solution is commonly known as acid washing. This procedure effectively eliminates stubborn stains, algae buildup, and mineral deposits that regular cleaning methods cannot address. The visual result of this process is often a brighter, cleaner pool surface, restoring its original appearance.
Undertaking this resurfacing technique offers several advantages, including extending the lifespan of the pool’s finish by preventing deterioration caused by accumulated contaminants. It can also significantly improve water quality and reduce chemical usage by removing embedded organic matter that consumes sanitizers. Historically, this method has been employed as a means of deep cleaning and restoration for pools that have experienced significant neglect or staining.
