Outdoor plastic chairs are a staple of patios, decks, and gardens around the world. They’re affordable, durable, and weather-resistant – making them perfect for enjoying the great outdoors. However, constant exposure to the elements inevitably leads to dirt, grime, mildew, and stains. Knowing how to properly clean your outdoor plastic chairs will not only keep them looking their best but also extend their lifespan. This comprehensive guide will walk you through the best methods, from simple washes to tackling stubborn stains, ensuring your outdoor seating remains inviting and comfortable.
Understanding the Enemy: Identifying Common Types of Dirt and Grime
Before diving into cleaning techniques, it’s helpful to understand what you’re up against. Identifying the type of dirt and grime on your plastic chairs will allow you to choose the most effective cleaning method.
Dirt, Dust, and Pollen
These are the most common culprits, accumulating on outdoor furniture from wind, rain, and general outdoor activity. They’re typically easy to remove with a simple wash.
Grime and Grease
Grime often consists of a combination of dirt, dust, and airborne pollutants that cling to the plastic surface. Grease can come from food spills, sunscreen, or even oily residues from plants. These require a more targeted cleaning approach.
Mold and Mildew
Humid environments foster the growth of mold and mildew, which appear as black, green, or grey spots on your plastic chairs. These can be unsightly and potentially harmful, requiring a cleaning solution specifically designed to kill these organisms. Mold and mildew should be addressed promptly to prevent them from spreading and causing further damage.
Stains from Leaves, Berries, and Beverages
Spilled drinks, fallen leaves, and squashed berries can leave unsightly stains on plastic chairs. These stains can be challenging to remove, especially if they’ve been left to sit for a long time.
The Basic Cleaning Method: A Gentle Wash for Everyday Dirt
For regular maintenance and removal of light dirt and dust, a simple wash is often all that’s needed. This method is gentle on the plastic and effective for keeping your chairs looking fresh.
Gather Your Supplies
You’ll need a few essential items: a bucket, warm water, dish soap (a mild formula is best), a soft-bristled brush or sponge, and a garden hose. A microfiber cloth is also helpful for drying.
Prepare the Cleaning Solution
Fill your bucket with warm water and add a squirt of dish soap. Stir the mixture to create a soapy solution. Avoid using excessive amounts of soap, as this can leave a residue.
Wash the Chairs
Dip your brush or sponge into the soapy water and scrub the chairs thoroughly. Pay attention to areas where dirt tends to accumulate, such as the legs, seat, and backrest.
Rinse with Water
Use a garden hose to rinse the chairs thoroughly, removing all traces of soap. Ensure no soapy residue remains, as this can attract more dirt and grime.
Dry the Chairs
Wipe down the chairs with a clean microfiber cloth to speed up the drying process. Alternatively, you can allow the chairs to air dry in the sun.
Tackling Stubborn Grime: Stronger Cleaning Solutions
When a simple wash isn’t enough, you’ll need to employ a stronger cleaning solution to tackle stubborn grime and grease. Several options are available, each with its own advantages and disadvantages.

Covering the Chairs
When not in use, cover your chairs with waterproof covers to protect them from the elements. This will prevent dirt, rain, and UV rays from damaging the plastic.
Storing the Chairs
During the off-season or periods of prolonged inactivity, store your chairs in a shed, garage, or other sheltered location. This will protect them from harsh weather conditions and prevent them from becoming excessively dirty.
Avoid Placing Chairs Under Trees
Avoid placing your chairs directly under trees, as falling leaves, sap, and bird droppings can quickly soil the surface.
Maintaining Your Chairs: Prolonging Their Lifespan
Proper maintenance is key to prolonging the lifespan of your outdoor plastic chairs. By following these tips, you can keep your chairs looking great for years to come.
Inspect Regularly
Regularly inspect your chairs for signs of damage, such as cracks, chips, or fading. Address any issues promptly to prevent them from worsening.
Tighten Loose Screws
If your chairs have screws or bolts, check them periodically and tighten them as needed. Loose screws can weaken the structure of the chairs and make them more susceptible to damage.
Apply UV Protectant
Apply a UV protectant spray to your chairs to help prevent fading and discoloration caused by the sun’s harmful rays.
By following these cleaning and maintenance tips, you can keep your outdoor plastic chairs looking their best and enjoy them for many years to come. Consistent care is the most effective way to maintain the beauty and longevity of your outdoor furniture.
What cleaning solutions are safest for outdoor plastic chairs?
For most outdoor plastic chairs, a simple solution of dish soap and warm water is remarkably effective and safe. Avoid using abrasive cleaners or scouring pads, as these can scratch or dull the plastic surface. For tougher stains or mildew, consider a mixture of white vinegar and water. This natural cleaner is gentle yet powerful, helping to lift dirt and grime without damaging the plastic.
Always test any cleaning solution on a small, inconspicuous area of the chair before applying it to the entire surface. This precaution ensures that the solution doesn’t cause discoloration or any other unwanted effects. Additionally, remember to thoroughly rinse the chairs with clean water after cleaning to remove any residue from the cleaning solution, which could attract dirt.
How often should I clean my outdoor plastic chairs?
The frequency of cleaning your outdoor plastic chairs depends on your local climate and how often they are used. Generally, cleaning them once a month is a good practice to prevent the build-up of dirt, pollen, and mildew. If you live in a particularly dusty or humid area, or if the chairs are used heavily, you might consider cleaning them more frequently, perhaps every two weeks.
Regular cleaning not only keeps your chairs looking their best but also helps prolong their lifespan. By removing dirt and grime regularly, you prevent these elements from embedding themselves into the plastic, making them harder to remove later. Addressing stains and spills promptly also prevents them from becoming permanent.
What’s the best way to remove stubborn stains from plastic chairs?
For stubborn stains, create a paste using baking soda and water. Apply the paste directly to the stain and let it sit for about 15-20 minutes. The baking soda acts as a mild abrasive, helping to lift the stain without damaging the plastic. After the waiting period, scrub gently with a soft brush or cloth and rinse thoroughly with water.
Another effective method involves using a solution of bleach and water, but exercise extreme caution when using bleach. Dilute the bleach according to the product’s instructions and always wear gloves and eye protection. Apply the solution to the stain, let it sit for a few minutes, and then rinse thoroughly with water. Ensure the chairs are completely dry and that no bleach residue remains before using them.
Can I use a pressure washer to clean plastic chairs?
While a pressure washer can seem like a quick and easy solution, it’s important to use caution when cleaning plastic chairs with one. The high pressure can potentially damage or warp the plastic, especially if the chairs are made of a thinner material. If you choose to use a pressure washer, select the lowest possible pressure setting.
Always test the pressure washer on an inconspicuous area first to gauge its impact on the plastic. Maintain a safe distance between the nozzle and the chair, and use a wide-angle nozzle to distribute the water pressure more evenly. Avoid focusing the stream on one spot for too long, as this can lead to damage. Rinse thoroughly after cleaning to remove any loosened dirt and debris.
How do I prevent mildew from growing on my outdoor plastic chairs?
Preventing mildew growth starts with proper cleaning and ensuring the chairs are completely dry after each cleaning. When drying, avoid stacking the chairs on top of each other until they are thoroughly air-dried, as trapped moisture can encourage mildew growth. Positioning the chairs in a well-ventilated area or under direct sunlight can accelerate the drying process.
Consider using a mildew-resistant cleaner or adding a mildew inhibitor to your regular cleaning solution. Regularly wiping down the chairs with a damp cloth can also help prevent the build-up of moisture and organic matter that mildew thrives on. Covering the chairs when not in use can further protect them from moisture and debris, reducing the likelihood of mildew growth.
How do I clean textured plastic chairs?
Textured plastic chairs require a bit more attention due to the grooves and crevices that can trap dirt and grime. A soft-bristled brush is essential for getting into these hard-to-reach areas. Dip the brush into your cleaning solution (dish soap and water or vinegar and water) and scrub gently to loosen the dirt and debris from the texture.
After scrubbing, rinse the chairs thoroughly with clean water, paying particular attention to ensure all soap or cleaner residue is removed from the textured areas. A garden hose with a spray nozzle can be helpful for this. To ensure the chairs are completely dry, consider using a clean, dry cloth to wipe down the textured surfaces, preventing water from pooling and potentially attracting dirt or mildew.
How do I protect my plastic chairs from fading in the sun?
Prolonged exposure to sunlight can cause plastic chairs to fade and become brittle over time. To help protect them from fading, consider applying a UV protectant spray specifically designed for plastics. These sprays create a protective barrier that shields the plastic from harmful UV rays. Reapply the spray periodically, following the manufacturer’s instructions.
Another effective method is to simply store the chairs in a shaded area or under a patio cover when they are not in use. If you don’t have a covered area, consider investing in furniture covers to protect them from the sun and other elements. Regularly cleaning the chairs also helps to remove any dirt or grime that can exacerbate the effects of UV radiation.
