For a common stain that occurs often on the plaster of a pool such as metal the following cleaning methods can help. A metal stain can come from a ponytail holder, a pop top, soda can or coin that falls into the pool. When left without being noticed for a period of time a metal stain will occur.

The second method involves using a concentrated amount of granular chlorine on the affected spot. To effectively do this you must turn off the pools filter and pump. The water should be still. Place the granular chlorine in nylon or some material that will allow it to flow through and dissolve on the stain. It should work as a bleaching agent and within a few hours of the pack sitting on the stain the chlorine will be gone and the stain should be removed.
