How Do I Clean Plastic Surfaces?

Plastic surfaces are everywhere in our homes, from kitchen counters and furniture to kids' toys and even outdoor patio furniture. While plastic is durable and versatile, it can get grimy fast. Grease, stains, scuffs, and that inevitable build-up of grime are all part of the package when it comes to plastic. The good news? It’s super easy to clean if you know the right tricks.

As someone who runs a house cleaning business, I've cleaned all kinds of plastic surfaces—indoors and out. Over the years, I've learned which methods work best for a deep, thorough clean that makes plastic look brand new again. Whether you're tackling scuffed-up chairs or sticky kitchen surfaces, Here are six go-to methods for cleaning plastic surfaces: warm soapy water, baking soda paste, vinegar, rubbing alcohol, a Magic Eraser, and finally, hydrogen peroxide with sunlight.

1. Warm Soapy Water

I always start with the basics. Warm soapy water is your best friend when cleaning plastic, especially for general maintenance or light cleaning. Sometimes the simplest methods are the most effective, and this one definitely fits the bill for day-to-day cleaning.

How to Do It:

1. Fill a bucket or sink with warm water. Add a few squirts of dish soap (nothing fancy required).
2. Wipe down the plastic surface. Use a sponge or soft cloth, dip it in the soapy water, and wipe down the entire surface.
3. Rinse and dry. Once the surface is clean, wipe it down with a cloth dampened in clean water to remove any soap residue. Then dry the surface with a towel.

This method is perfect for plastic patio furniture, outdoor toys, or even your kitchen cutting boards. One time, I had a client with a backyard full of plastic furniture that had been sitting in the sun and rain for months. After scrubbing it down with some soapy water, it looked nearly new again—no special products required.

2. Baking Soda Paste

Baking soda is a powerhouse when it comes to cleaning, especially for plastic surfaces that have scuffs or stubborn stains. It’s mildly abrasive, which means it scrubs away grime without scratching the plastic.

How to Do It:

1. Make a paste. Mix baking soda with a little water until it forms a thick paste.
2. Apply to the surface. Use a soft cloth or sponge to rub the baking soda paste onto the stained or scuffed areas. Apply a little elbow grease to really get in there!
3. Rinse and dry. After scrubbing, wipe away the paste with a damp cloth, and then dry with a clean towel.

Personal tip: I once used this method on a client’s white plastic lawn chairs that had scuff marks all over them from being dragged around the yard. After a good scrub with the baking soda paste, they were back to their original bright white. Baking soda has saved me more times than I can count!

3. Vinegar Solution

Vinegar is one of my go-to cleaners because it’s natural, safe, and super effective at cutting through grime, especially when dealing with greasy or sticky plastic surfaces. If you're dealing with plastic in the kitchen—like fridge shelves or food containers—vinegar will be your best friend.

How to Do It:

1. Mix your solution. Combine equal parts white vinegar and water in a spray bottle.
2. Spray and wipe. Spray the solution directly onto the plastic surface and wipe it down with a cloth or sponge.
3. Rinse and dry. Like with other methods, follow up with a clean, damp cloth and dry with a towel.

Pro tip: Vinegar is fantastic for cleaning plastic containers that might have lingering odors from food. I once cleaned a client’s collection of plastic food storage containers that had absorbed odors from everything from garlic to curry. The vinegar wiped out the smells almost instantly!

4. Rubbing Alcohol

If you’ve ever struggled to remove stubborn sticky residue from a plastic surface—like old price tags or adhesive from labels—rubbing alcohol is the solution. It cuts through glue and grime while disinfecting the surface at the same time.

How to Do It:

1. Apply rubbing alcohol. Soak a cotton ball or cloth with rubbing alcohol and apply it to the sticky area.
2. Let it sit. Allow the alcohol to work for a minute or two, loosening up the adhesive.
3. Wipe away. Use a clean cloth to wipe away the residue. For extra-sticky spots, you may need to repeat the process.

This trick has saved me so many times when cleaning items with leftover sticker residue! A while back, I was cleaning out a playroom and spent hours removing stickers from plastic toy boxes and furniture. A little rubbing alcohol made all the difference—it’s my secret weapon for stubborn stickiness.

5. Magic Erasers

When plastic surfaces are heavily scuffed or have tough stains, I always reach for a Magic Eraser. This sponge-like cleaner is incredibly effective at scrubbing away stains, grime, and scuffs without damaging the plastic. It’s like the heavy-duty version of a sponge.

How to Do It:

1. Wet the Magic Eraser. Dampen it with a little water—no soap needed.
2. Scrub the surface. Gently scrub the plastic, focusing on scuffed or stained areas.
3. Rinse and dry. After scrubbing, wipe down the surface with a clean, damp cloth to remove any leftover debris, then dry with a towel.

I once used a Magic Eraser to clean up the plastic siding of a client's outdoor playhouse, which had been covered in mud, scuffs, and who knows what else. The Magic Eraser took off every mark, and it looked brand new by the end of the day. These things work like a charm!

6. Hydrogen Peroxide and Sunlight: For Whitening Yellowed Plastic

Over time, white plastic can start to turn yellow, especially when exposed to sunlight or high heat. This happens often with things like plastic electronics, appliances, or patio furniture. Luckily, hydrogen peroxide can reverse this yellowing effect when combined with sunlight.

How to Do It:

1. Coat the plastic in hydrogen peroxide. Use a sponge or cloth to apply a generous layer of hydrogen peroxide to the yellowed surface.
2. Cover with plastic wrap. This step helps keep the hydrogen peroxide in place while it works.
3. Set it in the sun. Place the item outside in direct sunlight and leave it there for a few hours. The sunlight will activate the hydrogen peroxide and help lift the yellowing.
4. Wipe and dry. After a few hours, remove the plastic wrap, wipe down the surface, and dry thoroughly.

Personal anecdote: I once had a client with an old, yellowed plastic garden bench that had been sitting in the sun for years. After treating it with hydrogen peroxide and letting it soak up some sunlight, the transformation was incredible—it looked almost like new!

Tips for Maintaining Clean Plastic Surfaces

After you’ve cleaned your plastic surfaces, it’s a good idea to take steps to keep them clean and prevent future stains. Here are a few tips that have worked well for me over the years:

• Regular maintenance. Wipe down plastic surfaces regularly with warm soapy water or a vinegar solution to prevent grime from building up.
• Avoid harsh chemicals. Plastic can be sensitive to some cleaning products, so avoid using bleach or ammonia, as these can degrade the material over time.
• Use a protective cover. For outdoor plastic furniture, use a protective cover when not in use, especially during bad weather. This helps keep them clean and prevents discoloration.

Plastic is a versatile and durable material, but it does need regular cleaning to keep it looking its best. Whether you're dealing with outdoor furniture, kitchen containers, or kids' toys, these six methods will help you tackle any mess and leave your plastic surfaces sparkling clean. From soapy water to rubbing alcohol and even hydrogen peroxide, each method has its place depending on the type of grime you're facing. With a little patience and elbow grease, you can keep your plastic surfaces looking fresh and new for years to come!

Happy cleaning!
