How To Remove Oxidation From Plastic Chairs: a Useful Guide

Jul. 20, 2021

Preparing the garden for spring and summer is a daunting task. Before you can properly enjoy your outdoor living space again, there is a long list of chores you need to do, from raking to weeding, from scrubbing to tidying. If you have plastic furniture in your garden, then you may notice that over time, it will begin to fade, with white residue appearing in the patches.

This chalky color is caused by oxidation. Therefore, we will look at the reasons for it and two methods of how to remove oxidation from plastic chairs so that you can breathe a new life into your patio furniture.

What causes oxidation?

The oxidation you see on the plastic chair outside is basically like rust on the plastic version. Exposure to the air and sunlight is the culprit, because the chemicals contained in the plastic will react with oxygen in the air, coupled with ultraviolet radiation from the sun, which will cause photo-oxidation.

This will cause the plastic to degrade over time, as the compound loses electrons during the oxidation process. More modern plastics contain additives to help them stabilize. Although this does not protect them from the oxidation process, it will slow down the oxidation process.

How to remove oxidation?

There are some methods you can use at home to restore plastic. But first, you must prepare the surface.

1. Wash off any dirt

The first thing you need to do is to wipe the chair thoroughly. Take a bowl of soapy water and wipe the plastic chair clean with a sponge or cloth. Do not use detergents as they will scratch the plastic surface and make it look worse. Rinse the soapy water with the clean water in the hose.

2. Kill the mold

The next thing you need to do is to remove the mold with vinegar and water solution. Add a quarter cup of white vinegar per quart of water and spray it on the chair. Let it sit on the chair for 15 to 20 minutes before taking a piece of cloth to the chair.

Soak the cloth in white vinegar to wipe off the mold spots you see. Rinse the chair thoroughly with the hose again.



3. Remove stains

Baking soda and wax

If you want to use baking soda and waxing method, then you can work directly on a clean and damp chair.

Step 1: Moisten the sponge in a bowl of warm water and sprinkle baking soda on it. Gently rub the chair with a sponge, rinse, and add more baking soda as needed to cover the entire chair.

Step 2: Rinse the chair with clean water from the hose, use a towel or let it bake in the sun for a while, and dry the chair completely.

Step 3: Take a car paste wax (similar to carnauba paste wax) and apply it on the chair with a rag. Keep it for about 5 minutes, then polish it with a clean soft cloth.

Plastic furniture renewed

Putting your plastic chairs away when they are not in use will certainly help slow down the oxidation process, but to some extent, you will have a choice in front of you. Spend money on brand new patio furniture, or spend some time repairing them.
