The Best Methods to Remove Oxidation From Plastic

By Rose Kerr

Plastic exposed to the sun turns dull and ugly after prolonged use. When this happens to the accessories of your car – in particular – the plastic has a worn-out look. Some examples of plastic car parts that get oxidized (and ugly) over time are the car’s plastic bumpers, the side mirrors, and the dashboard. One solution would be to change the accessories, which could be costly. The same applies to fiberglass boats that after a while lose their shine and look old and neglected because of plastic oxidation. You can, however, regain the original shine and bring look of the plastic at a fraction of the cost of replacement.

Miracle Coat

The Miracle Coat is a solution that instantly restores plastic of fiberglass products to their original sheen and luster. The product costs about $22 for a 2-ounce bottle, at the time of publication. It can be used to remove oxidation as well as buffable scratches. You need a micro-fiber cloth applicator (included with the product) with which you will apply the product and buff it just like you would with wax. You will need to re-apply the product every six months to restore the shine.

Vertglas GelCoat Restoration System

Priced at approximately $27 for a 16-ounce bottle, at the time of publication, the Vertglas GelCoat oxidation remover promises to restore the plastic part to its original looks. The product can be bought separately or part of the Vertglas GelCoat Restoration System that costs about $79 and includes products that removes, shines, protects and maintains the plastic parts. The product comes with a money-back guarantee and impressive testimonials as mentioned on its website. Four steps are required to restore the shine. Use Vertglas oxidation remover to remove the oxidation; wash with Vertglas anti-spotting agents; apply Vertglas co-polymer sealer; and buff for shine. The shine is designed to last the year, no matter what weather to which the plastic/ fiber is exposed.

Back for Good

Back for Good is a kit that contains cleaner, application pad, disposable gloves and the Back for Good solution. The product is priced at about $25 for 4 ounces, at the time of publication, and promises to wipe away the oxidation from any type of plastic, especially car accessories. The product will restore the plastic’s shine no matter what type or color of plastic or how long or how badly oxidized. The restoration process consists of two steps – washing the plastic and coating the plastic piece with the Back for Good solution. It is especially recommended for bumpers, window trims and wiper arms -- though it says it restore any faded plastic.

Home Remedy

A tried and tested home remedy is peanut butter. Wash the plastic with soap and water to remove all dirt and grime from its surface. Let it dry naturally. Take the peanut butter and spread generously on the surface. Let it rest for about 15 to 20 minutes. Wipe with soft towel thoroughly. It restores the shine and color to any type of plastic.
