Oxidation is caused by sun exposure and can affect almost any material, such as plastic, car paint, metal and aluminum. Oxidation causes the surface of the material to become dry and chalky. If left untreated, it will eventually eat through the material. Removing oxidation before that happens is fairly easy and can be done with a rubbing compound followed by a coat of polishing wax. The wax will bring the shine back to the surface of the material and also protect it from future oxidation.
Things You'll Need
- Mild detergent
- Rubbing compound
- Boat wax
Fill a bucket with warm water and add a mild detergent. Thoroughly wash the shutters with a sponge, removing any dirt or other buildups. Rinse the shutters with clean water and dry them with a towel.
Apply rubbing compound to the oxidized areas and lightly rub directly on the oxidation in circular motions until the surface is smooth to the touch. Do not rub through the paint; just remove the oxidation. Rinse the shutters with clean water and dry them.
Apply a boat wax or polish to the shutters and let it dry. Buff the wax into the shutters using a clean rag. This will seal the surface of the paint to protect it from the sun as well as leave a nice finish on the shutters.
