How to Remove Blue Green Copper Stains From a Toilet

It is not uncommon for stains to appear in toilet bowls. Mineral build-up--such as copper, calcium and lime--is a typical cause of toilet bowl stains. Blue-green marks located in your toilet bowls are the result of copper stains. Blue-green stains will cause your toilet to look dingy and dirty. Toilet bowl cleaners, which are available at local department stores, can easily remove copper stains. Alternatively, use household items to successfully remove copper stains from toilet bowls.
