However, swimming in a dirty pool can put a damper on the fun and keep people out of the pool. Stains occur naturally in a pool and require regular maintenance to keep them out. Sometimes, it can be fairly easy to get rid of stains, but other times, those hard-to-remove spots can take a bit more than a simple scrub. Pool stains on the wall or floor of a swimming pool can be caused by metals in the pool water, or by an organic material left in the pool.
