How to Clean and Care for Plastic Garden Furniture

Last update: 15 December, 2022

If you don’t quite know how to clean and take care of your plastic garden furniture, we invite you to read this article to the end to learn what you can and can’t do. We know that this furniture is a favorite when it comes to choosing patio furniture, as it’s very durable and requires little maintenance.

The most common models are the white plastic ones, which are often placed near a pool, on a terrace, and in other outdoor spaces. However, during the winter, they’re often not used much, so they tend to accumulate dirt and grime.

If they’re not cleaned often, they get damaged and even seem to have changed color. Bearing this in mind, let’s review how we can restore them to like-new condition.

Why clean plastic?

During the spring and summer, garden furniture stays clean because we use it often. However, when the days get colder, we stop using it. Therefore, we often don’t clean them regularly.

It’s during this time when the dirt accumulates and we have to do a deeper cleaning.

Also, because it’s made of plastic, this type of furniture is very resistant to different weather conditions and ultraviolet (UV) rays. However, when it’s exposed to the sun for a long time, it can crack and discolor.

That’s why we suggest that you protect it when it’s not in use.

Finally, remember that plastic is a porous material that causes this type of furniture to accumulate germs. They will proliferate thanks to the remains of organic material, such as food waste.

The best tips and methods to care for plastic furniture

Now we’ll dive into the best ideas to protect your plastic furniture. You will be able to enjoy your furniture for a long time if you follow these tips.

Method 1: Detergent, acetone, and baking soda to clean plastic garden furniture

This trio is infallible when it comes to deep cleaning. Each one does its part, and together they will make your plastic furniture look as good as new. You will need 100 ml of dishwashing detergent, one tablespoon of baking soda, and 100 ml of acetone.

Mix the three ingredients in a bowl well. Then, we suggest you place the preparation in a container with a spray bottle to make its application easier and more effective.

Next, spray the furniture with this liquid and rub the surface with a rough sponge. Once the sponge has been wiped over all the nooks and crannies of chairs and tables, rinse with plenty of water.

If there are stubborn stains, leave the mixture on for 15 minutes before removing the product. Similarly, if they don’t come out, moisten a cotton swab with acetone and wipe it over the stain.

This can always be done with white plastic furniture. If yours are a different color, first do a test on an inconspicuous area, just in case.

Method 2: Coconut soap, baking soda, and hydrogen peroxide

In this case, we are going to replace the detergent with coconut soap and the acetone with hydrogen peroxide. As you will see, baking soda is a constant, and you can’t do without it. Why? Because its granulated texture works as an excellent exfoliant in addition to being a good whitener.

The proportions are the same as in point 1, as is the preparation method. In this case, leave the product to act for half an hour before rinsing.

Method 3: White vinegar, baking soda, and dishwasher

For this third alternative, you will use 100 ml of detergent, 100 ml of vinegar, 100 ml of water, and one tablespoon of baking soda. The way to apply is the same as the two previous methods. Remember that the sponge that you use must be rough.

Method 4: Ammonia

In this case, you’ll dilute ammonia in warm water and add detergent. It’s important not to mix products such as bleach, alcohol, or ammonia, but use them separately.

Regardless of how you choose to clean the furniture, it’s essential to wear gloves and safety goggles, if necessary.

Plastic furniture benefits by the action of baking soda thanks to its bleaching power.

Method 5: A high-pressure cleaner

This method never fails, because the pressure exerted by the water on the furniture helps to remove virtually all traces of dirt. If you notice that the dirt and stains don’t come off, you can first try some of the previous methods and then remove the details with this machine.
