Plastic polishing is one of those projects that many people assume you simply cannot do because the material is easily damaged. In most circumstances, polishing is reserved for products made out of metal. Plastic polishing can be done, however, and it is important if you wish to keep your pieces looking great.

You will find plastic everywhere you look, from bathroom sinks to the handles on your stove or refrigerator. Plastic can become scratched or stained quite easily and plastic polishing can restore it to its former glory. Plastic manufacturing companies have their own methods of polishing that cannot be copied at home due to the fact that they use very harsh chemicals, but the article below will share with you some very simple and basic ways to make plastic polishing an easy chore.

Toothpaste

This works on minor surface scratches. You can use toothpaste for plastic polishing on everything from counters to CD discs, and any toothpaste will work. You simply need to use a cotton pad with a very small amount of toothpaste on it. Scrub the area to be polished and then rinse it off with cool water. This works because toothpaste is a mild abrasive.

Banana and Glass Cleaner

You will need a banana with the peel for this method. Like toothpaste, this plastic polishing strategy is meant for smudges and minor scratches.

Peel a banana and cut off a chunk. Then, rub the plastic with the cut end of the banana in a circular motion; do not use enough pressure that you crush the banana. After the banana has been applied wrap the banana peel around your finger and wipe the plastic surface with it. You can use a clean towel with medium pressure to remove the banana residue, moving in a circular motion on the plastic surface for several minutes. Lightly spray the plastic down with the glass cleaner and wipe off to restore shine.

Liquid Metal Polish

Any brand of liquid metal polish will do and is great for removing deeper scratches as well as restoring the shine to plastic. Don't forget; when working with any chemical, it's important to handle with care and use protective gloves.

Shake the bottle very well and put a drop of the polish on a clean rag. Dab it on the plastic and then rub it on in a circular motion. You will need to scrub the plastic in this fashion for up to 20 minutes, depending on the depth of the scratch, while the chemical actually removes the top layer of the plastic. Rinse the plastic off with cold water and buff it clean with a lint-free towel.

Sanding

This plastic polishing method should only be used on plastic in very poor condition. You'll need 400-grit, 800-grit, 1000-grit, and 2000-grit sandpaper, as well as plastic cleaner and plastic polish. You'll want to use wet sanding, so soak the sandpaper in water prior to using it. Lightly sand the surface with the lowest grit sandpaper, working toward the highest, sanding for several minutes apiece. Buff with a soft towel afterward, rinse, then buff with the plastic polish and rinse again.
