Rust stains in toilets are a common problem that can be caused by a variety of factors, including hard water, iron pipes, and old plumbing. Rust stains can be unsightly and difficult to remove, but there are a few simple steps you can take to get rid of them.
One of the most effective ways to remove rust stains from a toilet is to use a commercial rust remover. These products are typically made with a strong acid, such as hydrochloric acid or muriatic acid, which will dissolve the rust. Be sure to follow the directions on the product label carefully, and take precautions to protect your skin and eyes from the acid.
