We suggest doing proper research before treating your swimming pool stains. For example, this picture shows what bad advice can do to a pool surface. This person added a granular chlorine product to his pool that caused the surface to turn black within a few hours. His pool shop misdiagnosed the stain and the wrong treatment made it much worse within hours.

Also, some pool advice websites give advice that is not only damaging to your pool but also very dangerous to your surface. Following this advice (such as pouring pure acid down a pipe) can harm the surface permanently. This means that even if this process does remove the stain that there will be a streak left behind from the acids.

Don’t drain your pool to remove stains

These days there are other options for stain removal that do not require the pool to be drained or acid washed. These treatments can work effectively with the water still in the pool. Conversely, pool shops will often recommend acid washing because they do not know how to remove the stain using other methods. So we would encourage you to investigate these options before draining your pool.

Stain removal specialists such as The Pool Stain Removers may be worth considering if you have stains. They specialize in treatments that remove stains without draining the water.
