You can give old bathtubs a fresh look by using cleaning solutions found in your kitchen cupboards and eraser pads that fight stubborn stains. Bathtub surfaces dull over time from abrasive cleaners and scrubbing brushes that etch and scratch into the enamel. Dirt and soap scum become trapped within the scratches and fade the bathtub's finish. Using certain products help to bring the newness back to an old bathtub.
Put on rubber gloves to protect your hands.
Mix a solution of one part water and one part white vinegar, and pour into a spray bottle. Spray the solution onto the old bathtub and allow it to sit for 15 minutes.
Spray more of the vinegar solution onto the tub and scrub it with a nylon brush. The vinegar eats through any mildew, mold and dirt stains, and the nylon brush loosens the stains from the tub surface.
Rinse the grime away with warm water and a clean rag.
Form a paste by mixing three or four drops of water into a handful of baking soda. Apply the paste to any leftover stains in the bathtub and leave it on for two to three hours. Scrub the tub clean with the nylon brush, and rinse the baking solution away.
Apply a cleaning eraser pad to the old bathtub. Wet the eraser pad, and wipe it over the surface of the tub. Rinse the tub after using the eraser pad. Eraser pads remove stubborn stains on a tub's enamel.
Mix a solution of one part bleach and four parts water, and sponge it onto the entire tub surface. Allow the bleach solution to remain on the tub for 30 seconds to one minute, then rinse it away thoroughly with cool water.
