Remove Rust Stains
Rust is formed when iron begins to corrode and creates an ugly brown surface on bathroom fixtures. It is important to remove these stains at first sight, because if you accidentally rub up against them they will leave a tough stain on your clothes.
Rubbing with a cut lemon can remove many sink and tub rust stains. Just rub the half lemon directly on the stains and they should start to come off.
