How to Clean White Plastic Chairs

Plastic chairs are a popular choice for outdoor seating because they are lightweight, inexpensive, and weather-resistant. However, white plastic chairs are especially prone to showing signs of wear, including dirt and discoloration, due to their light color.

White plastic chairs are durable, practical, and easy to clean. They’re ideal for outdoor use as dining chairs, around pools and other wet areas, or as seating on patios and decks.

We all love the look of a beautiful white deck chair or plastic chaise lounge on the patio, by the pool, or in the backyard. Unfortunately, like a lot of things that bring us pleasure, white plastic chairs have a tendency to get dirty and lose their luster.

But don’t fret, because, with just a little bit of know-how and some common household products, you can restore your outdoor white plastic chairs to their former glory…

8 Ways to Clean White Plastic Chairs

Plastic chairs are a wonderful thing for those of us who like to entertain outdoors. They’re lightweight and easy to move around, and they don’t rust. However, because they’re white, any stain or speck of dirt stands out. Keeping plastic chairs clean can be a challenge since dirt tends to cling to the surface.

Here are 10 ways you can keep your chairs in tip-top shape.

1. Use a nylon scrub brush with dishwashing soap

A nylon scrub brush with dishwashing soap can loosen up any grime or dirt that’s clinging to the surface. Once you’ve given the chair a good scrubbing, rinse it off with water, dry it, and it will be as good as new.

If you need to spot clean your chairs, use liquid dish soap mixed with water. Dish soap is effective at cutting through grime and grease, making it ideal for cleaning plastic chairs that have been exposed to the elements over time.

Apply some of the dish soap to a soft cloth, wet with warm water, and wipe down your chairs for an easy cleaning solution with no harsh chemicals needed.

2. Use baking soda

Baking soda is great for removing stains on plastic surfaces, but you’ll need to make a paste first.

Method1: Mix equal amounts of baking soda and water until it reaches a thick consistency. Scrub the mixture into the chair using a sponge or soft cloth.

Method 2: Sprinkle baking soda over the surface of each chair and allow it to sit for five minutes. Scrub the chairs with a soft brush dipped in warm water before rinsing away the residue with more warm water.

3. Use bleach (the right way)

If you have stubborn stains that won’t come off with baking soda or dishwashing soap, then consider using bleach (but only if the chairs are safe for bleaching). Combine 1/2 cup of bleach for every gallon of water.

Remove Mildew With Bleach

If your white plastic chairs are stained with mildew, use bleach to remove it safely and easily. Fill a spray bottle with undiluted bleach and spray it liberally over all parts of each chair, including both the seat and backrest areas. Allow the bleach to sit for 15 minutes before rinsing it off thoroughly with clean water

4. Try a Magic Eraser

Mr. Clean’s Magic Eraser (Available at Amazon) is a cleaning product that erases stains from many surfaces, including white plastic chairs. It’s water-based and contains no harsh chemicals or abrasives, so it’s safe on all types of plastic surfaces.

You should test the product in a small area before using it on your entire chair, especially if the chair has a different color than white.

5. Use Paint Thinner

Use paint thinner on stubborn stains or marks on your white plastic chairs if other methods don’t work well enough for you. Apply paint thinner to an old rag, then rub down your chair to remove the stain or mark. Rinse the chair off after using paint thinner and set it out to dry in the sun so that there is no residue left behind from the paint thinner fumes.

6. Use olive oil or baby oil for stubborn stains

If you have stubborn stains on your white plastic chairs, try using olive oil or baby oil to remove them successfully. Use an old rag dipped into some of the oil and rub down your chair to remove the stains. This works best for older stains that have been sitting around for some time.

7. Clean with Soap and Water

This is the simplest method and may be all you need if the chairs aren’t badly stained or soiled. Mix some dish soap with warm water in a bucket. Dip a soft cloth into the solution and wring out most of the water. Wipe down each chair with a damp cloth until all of the dirt is removed.

Rinse the cloth often in clean water as it gets dirty. Wash off any remaining soap residue with clean water and dry with a towel.

8. Clean With Vinegar

Vinegar can remove stubborn stains from white plastic chairs that don’t come off with soap and water alone. Fill a spray bottle with undiluted vinegar and spray it liberally over the chair seats and backs.

Let the vinegar sit for about 15 minutes before scrubbing each chair with a brush dipped in warm water to remove stains, mold, or mildew from the surface of the plastic. Rinse the chairs well with cool water when you’re finished, then wipe them down with clean cloths to dry them.

Use vinegar as a whitener

To whiten your white plastic chairs, try using a solution of half vinegar and half warm water to clean them. Then, rinse down the chairs thoroughly with cold water after cleaning them. This will remove most stains, as well as kill any bacteria that may be present on your plastic chairs.

Vinegar is also good for removing soap scum from your plastic furniture if you don’t like using harsh chemicals such as bleach around your home.

In summary, Cleaning outdoor furniture is moderate work, and it can be done with the right tools.

Spray the chairs liberally with a garden hose to remove dirt and debris from the surface. If you’re dealing with mold or mildew, set your water pressure too high so that you can blast away any spores that might be clinging to the chair.

Fill a bucket with lukewarm water and add 1 tbsp of mild dish soap for every gallon of water in the bucket. Mix up suds by hand with a soft-bristled brush.

Dip the brush into the soapy water and scrub each chair thoroughly, paying careful attention to any stains, mold, or mildew spots on the chair backs or seats. Rinse the brush frequently to keep dirt from being re-deposited on the chair as you attempt to clean it
