How to Clean Pool Stains on Vinyl Liner
Keeping a pool clean requires ongoing upkeep and maintenance. In addition to checking the chemical balance of the water on a regular basis, it is important to keep your water free from heavy metal build up such as iron, copper or calcium. Each of these metals can leave stains on your pool liner. The only way to combat this problem is to reduce the metal content in the water. This can be accomplished using a couple different chemical options. Does this Spark an idea?

Tips & Warnings
Pool supplies such as test kits, pool brushes and metal sequestering agents can be purchased at a local pool supply store or at online retailers (see Resources below).
Metal Gone and other metal sequestering chemicals will lower the pH balance in your pool. Test your water and adjust pool chemicals accordingly. Swimming in a pool with an improper chemical balance could be harmful to your health.
