Many appliances get rusty spots at some time or another. Refrigerators, stoves, dishwashers, washers, dryers and other household appliances are all prone to rusting. Although appliances have a protective coating that prevents rust, if this coating wears away or there is damage to an appliance, rust may form. The best line of defense is to treat the rust stains when you first notice them and to dry out areas that are prone to rust.
Scrub off the rust. Take a kitchen scrubbing pad or steel wool and scrub the rust stains. Clean off the area with a sponge or cloth. For surface rust or small stains this may be all that is needed.
Apply mineral oil. Using a scrubbing pad apply a small amount of mineral oil to the rust stains. Allow the mineral oil to settle into the rust. Ten or fifteen minutes later, scrub at the rust with steel wool or scrubbing pad. Use soap and water to wash off the rust and the oil residue. Dry the area.
Make a rust removing paste. Mix one part lemon juice with two parts borax to make a paste, then apply it to the rust stain on the appliance. Use a scrubbing pad or paper towel to do this. Let the mixture remain on the rust stains for 10 to 30 minutes, depending on the size of the rust, then scrub the stains with a scrubbing pad. Wipe the area clean to remove the rust and the paste. Wipe dry. Use this paste for stubborn rust stains.
