Lime and mineral deposits removal

You can remove lime and other mineral deposits by using a commercial cleaner that contains organic acids, designed specifically for this purpose (stay away from products that contain hydrochloride salts). For a homemade alternative, try making a paste of cream of tartar and hydrogen peroxide or cream of tartar and white vinegar. Scrub the paste lightly into the stain and allow to dry. Rinse thoroughly and buff dry.
