How Do I Clean Plastic Outdoor Furniture

How to Clean Plastic Outdoor Furniture

Plastic outdoor furniture offers a durable, weather-resistant, and relatively inexpensive option for patios, decks, and gardens. Its inherent properties, however, do not render it immune to the accumulation of dirt, grime, mildew, and other environmental debris. Regular cleaning is essential to maintain its appearance, extend its lifespan, and prevent the growth of undesirable organisms. This article provides comprehensive guidance on cleaning plastic outdoor furniture effectively.

Preparation: Assembling Supplies and Preparing the Area

Before commencing the cleaning process, it is crucial to gather the necessary supplies and prepare the surrounding area. This proactive step streamlines the cleaning operation and minimizes potential mess.

The following supplies are generally required:

Cleaning Solutions: Mild dish soap, white vinegar, baking soda, and commercially available plastic cleaners are all effective options, depending on the severity of the soiling.
Water Source: A garden hose with a spray nozzle provides efficient rinsing capabilities. A bucket of clean water is a suitable alternative if a hose is unavailable.
Cleaning Tools: Soft-bristled brushes, sponges, microfiber cloths, and old toothbrushes are essential for scrubbing and wiping down surfaces.
Protective Gear: Gloves protect hands from harsh cleaning solutions and potential irritants. Eye protection is recommended when using spray-based cleaners.
Optional Equipment: A pressure washer can be used for heavily soiled furniture, but caution is advised to prevent damage to the plastic.
Drop Cloth or Tarp: Laying down a drop cloth or tarp protects the surrounding area from spills and splatters.

Prepare the area by moving the furniture to a well-ventilated location, preferably outdoors. This allows for adequate ventilation during cleaning and facilitates easy rinsing. Clear the area of any obstacles, such as plants or personal belongings, that could be damaged during the cleaning process.

Basic Cleaning: Mild Soap and Water Approach

For routine cleaning and the removal of light dirt and grime, a simple solution of mild dish soap and water is typically sufficient. This method is gentle on plastic surfaces and avoids the use of harsh chemicals that could potentially damage or discolor the furniture.

The process is as follows:

Mix the Solution: In a bucket, combine warm water with a few drops of mild dish soap. The ideal ratio is approximately one tablespoon of soap per gallon of water.
Apply the Solution: Using a sponge or soft-bristled brush, apply the soapy water to the entire surface of the furniture. Ensure that all areas are thoroughly wetted.
Scrub Gently: Gently scrub the furniture to loosen dirt and grime. Pay particular attention to areas that are heavily soiled, such as crevices and joints. An old toothbrush can be used to reach tight spaces.
Rinse Thoroughly: Rinse the furniture thoroughly with clean water to remove all traces of soap. A garden hose with a spray nozzle is ideal for this purpose. Ensure that no soap residue remains, as it can attract dirt and leave streaks.
Dry the Furniture: Allow the furniture to air dry completely in the sun. Alternatively, wipe it down with a clean, dry microfiber cloth to expedite the drying process.

Addressing Stubborn Stains and Mildew

For more persistent stains, mildew growth, or discoloration, more aggressive cleaning methods may be required. Several effective solutions are available, each with its own set of advantages and disadvantages. It's important to test these solutions on a small, inconspicuous area of the furniture first to ensure they do not cause any adverse effects.

White Vinegar Solution: White vinegar is a natural disinfectant and cleaning agent that can effectively remove mildew and break down stubborn stains. To use vinegar, dilute it with water in a 1:1 ratio. Apply the solution to the affected areas, let it sit for 10-15 minutes, then scrub and rinse thoroughly.

Baking Soda Paste: Baking soda is a mild abrasive that can help to lift stains and remove mildew. Mix baking soda with a small amount of water to form a paste. Apply the paste to the stained areas, let it sit for 15-20 minutes, then scrub and rinse thoroughly.

Commercial Plastic Cleaners: A variety of commercially available plastic cleaners are specifically formulated for outdoor furniture. These cleaners often contain stronger detergents and solvents that can effectively remove tough stains and mildew. Always follow the manufacturer's instructions carefully when using these products. Wear appropriate protective gear, such as gloves and eye protection, and ensure adequate ventilation.

Bleach Solution (Use with Extreme Caution): Bleach is a powerful disinfectant that can effectively kill mildew and remove stains. However, it should be used with extreme caution, as it can damage or discolor some types of plastic. Always dilute bleach with water in a ratio of 1:10. Apply the solution to the affected areas, let it sit for only a few minutes, then scrub and rinse thoroughly. Never mix bleach with other cleaning agents, such as ammonia, as this can create toxic fumes. Wear appropriate protective gear, including gloves, eye protection, and a mask.

Pressure Washing (Use with Caution): A pressure washer can be an efficient way to clean heavily soiled plastic furniture. However, it is important to use caution, as the high pressure can damage or warp the plastic. Use a wide nozzle and a low pressure setting. Test the pressure washer on a small, inconspicuous area of the furniture first to ensure that it does not cause any damage. Keep the nozzle at a safe distance from the furniture (at least 12 inches) and move it in a sweeping motion. Avoid focusing the nozzle on one area for too long, as this can cause damage.

Protecting and Maintaining Plastic Outdoor Furniture

Once the plastic outdoor furniture has been thoroughly cleaned, taking steps to protect it from future soiling and damage can significantly extend its lifespan and maintain its appearance. Regular maintenance and preventative measures are key to preserving the furniture's integrity and minimizing the need for frequent deep cleaning.

Protective Coatings: Applying a UV-resistant protective coating to the furniture can help to prevent fading and discoloration caused by prolonged exposure to sunlight. These coatings create a barrier that shields the plastic from harmful UV rays. Choose a coating that is specifically formulated for plastic outdoor furniture and follow the manufacturer's instructions carefully.

Regular Cleaning Schedule: Establishing a regular cleaning schedule can prevent the buildup of dirt and grime. A quick wash with mild soap and water every few weeks is often sufficient to keep the furniture looking its best. This also helps to prevent the growth of mildew and other undesirable organisms.

Storage During Off-Season: During the off-season, when the furniture is not in use, storing it in a covered or enclosed space can significantly reduce its exposure to the elements. This helps to protect it from dirt, grime, mildew, and extreme temperatures, which can cause cracking or warping. If storing the furniture indoors is not possible, cover it with waterproof tarps to shield it from the elements.

Avoid Harsh Chemicals: Avoid using harsh chemicals or abrasive cleaners on plastic outdoor furniture, as these can damage or discolor the plastic. Stick to mild soap and water or specialized plastic cleaners. When using commercial cleaners, always follow the manufacturer's instructions carefully and test the cleaner on a small, inconspicuous area of the furniture first.

Promptly Address Spills and Stains: Addressing spills and stains promptly can prevent them from setting in and becoming more difficult to remove. Wipe up spills immediately with a clean cloth or sponge. For stubborn stains, use one of the cleaning methods described above.

By following these guidelines, individuals can effectively clean and protect their plastic outdoor furniture, ensuring its longevity and maintaining its aesthetic appeal for years to come. Consistent cleaning and maintenance are essential for preserving the furniture's value and enjoying its benefits for an extended period.
