How To Clean Outdoor Plastic Furniture and Fixtures

Outdoor plastic furniture and fixtures offer durability and affordability, making them popular choices for patios, decks, and gardens. However, prolonged exposure to the elements inevitably leads to the accumulation of dirt, grime, algae, and other unsightly residues. Regular cleaning is essential not only to maintain the aesthetic appeal of these items but also to prolong their lifespan and prevent permanent staining or damage. This article provides a comprehensive guide to effectively cleaning outdoor plastic, covering various methods, cleaning solutions, and preventative measures.

Before embarking on any cleaning process, it is crucial to identify the type of plastic material being cleaned. Different plastics have varying sensitivities to cleaning agents. For instance, some plastics may be prone to discoloration or damage when exposed to harsh chemicals. A general rule of thumb is to start with the gentlest cleaning method possible and gradually increase the intensity of the cleaning solution and scrubbing action as needed.

Preparation and Safety Precautions

Prior to commencing the cleaning process, gather the necessary supplies. These may include a garden hose, buckets, soft-bristled brushes (such as a toothbrush for tight corners), sponges, cleaning cloths, and appropriate cleaning solutions. Consider wearing gloves to protect the skin from prolonged contact with cleaning agents and to prevent potential irritation.

Choose a well-ventilated outdoor area away from sensitive plants or pets for the cleaning process. Move the plastic items to a space where water runoff will not cause damage or staining to surrounding surfaces. If using a pressure washer, exercise caution and maintain a safe distance to avoid damaging the plastic. It is also prudent to test the cleaning solution on an inconspicuous area of the plastic furniture or fixture before applying it to the entire surface.

Basic Cleaning Methods

The simplest method for cleaning outdoor plastic involves a combination of water and mild soap. A garden hose can be used to rinse off loose dirt and debris. Subsequently, a solution of warm water and dish soap can be applied to the plastic surface using a sponge or soft-bristled brush. Gently scrub the surface, paying particular attention to areas with stubborn stains or grime. Rinse thoroughly with clean water to remove all traces of soap residue.

For more persistent dirt and grime, a slightly stronger cleaning solution may be required. A mixture of water and vinegar can be an effective alternative to dish soap. Vinegar's mild acidity helps to break down dirt and mildew. Combine equal parts water and white vinegar in a bucket and apply the solution to the plastic surface. Allow the solution to sit for a few minutes before scrubbing with a brush or sponge. Rinse thoroughly with clean water.

Baking soda is another versatile cleaning agent that can be used to remove stubborn stains from outdoor plastic. Create a paste by mixing baking soda with a small amount of water. Apply the paste to the stained area and let it sit for approximately 15 to 20 minutes. Scrub gently with a brush or sponge and rinse thoroughly with clean water. Baking soda is generally safe for most types of plastic, but it is still advisable to test it on an inconspicuous area first.

Addressing Specific Stains and Issues

Outdoor plastic is susceptible to various types of stains, including mildew, algae, and rust. Each type of stain requires a specific approach for effective removal.

Mildew, a common problem on outdoor furniture, thrives in damp environments. To remove mildew from plastic, a solution of bleach and water is often effective. Mix one part bleach with ten parts water and apply the solution to the affected area. Allow the solution to sit for a few minutes before scrubbing with a brush. Rinse thoroughly with clean water. It is imperative to wear gloves and eye protection when working with bleach to avoid skin and eye irritation. Furthermore, bleach can damage certain types of plastic, so it is essential to test the solution on an inconspicuous area first and avoid prolonged exposure.

Algae growth is another common issue, particularly in shaded or damp areas. A pressure washer can be effective for removing algae from plastic surfaces. However, it is important to use a low-pressure setting to avoid damaging the plastic. Alternatively, a mixture of water and oxygen bleach (sodium percarbonate) can be used. Oxygen bleach is generally safer for the environment and less harsh than chlorine bleach. Mix the oxygen bleach with water according to the manufacturer's instructions and apply the solution to the affected area. Let it sit for the recommended time before scrubbing and rinsing thoroughly.

Rust stains can occur when metal objects come into contact with plastic surfaces. To remove rust stains, a commercial rust remover specifically designed for plastic may be used. Follow the manufacturer's instructions carefully and test the product on an inconspicuous area first. Alternatively, a paste of lemon juice and salt can be applied to the rust stain. Let the paste sit for a few hours before scrubbing and rinsing thoroughly. Lemon juice's acidity helps to dissolve the rust, while the salt acts as a mild abrasive.

Sunscreen stains are also a common problem on outdoor plastic furniture. These stains can be challenging to remove due to the oily nature of sunscreen. A degreasing dish soap can be helpful in breaking down the oil. Apply the dish soap directly to the stain and let it sit for a few minutes before scrubbing with a brush or sponge. Rinse thoroughly with clean water. For more stubborn sunscreen stains, a commercial stain remover specifically designed for oily stains may be necessary.

Deep Cleaning and Restoration Techniques

Over time, outdoor plastic can become heavily soiled and discolored, requiring a deeper cleaning approach. For heavily soiled plastic, a multi-purpose cleaner can be used. These cleaners typically contain stronger detergents and solvents that can effectively remove stubborn dirt and grime. Follow the manufacturer's instructions carefully and test the cleaner on an inconspicuous area first.

In some cases, outdoor plastic may develop a chalky or faded appearance due to prolonged exposure to sunlight. This chalking is caused by the degradation of the plastic surface by ultraviolet (UV) radiation. To restore the color and shine of faded plastic, a plastic restorer product can be used. These products typically contain oils and polymers that penetrate the plastic surface and restore its original appearance. Apply the plastic restorer according to the manufacturer's instructions.

For particularly stubborn stains or discoloration, professional cleaning services may be considered. Professional cleaners have access to specialized equipment and cleaning solutions that can effectively restore severely damaged plastic furniture and fixtures.

Preventative Measures

Preventing dirt and grime from accumulating on outdoor plastic is just as important as cleaning. Regular maintenance can significantly reduce the need for intensive cleaning and prolong the lifespan of plastic furniture and fixtures.

Covering outdoor plastic furniture when not in use can protect it from the elements and prevent the accumulation of dirt, dust, and debris. Use furniture covers specifically designed for outdoor use, ensuring they are waterproof and UV-resistant. Store plastic furniture indoors during the off-season to minimize exposure to harsh weather conditions.

Regularly wiping down outdoor plastic surfaces with a damp cloth can help prevent dirt and grime from building up. A quick wipe-down after rain or windstorms can remove loose dirt and debris before they have a chance to adhere to the plastic surface. Avoid using abrasive cleaners or scouring pads, as they can scratch the plastic.

Applying a protectant spray specifically designed for outdoor plastic can help to repel dirt, water, and UV rays. These protectant sprays create a barrier that prevents dirt and grime from adhering to the plastic surface and protects against fading and discoloration. Reapply the protectant spray periodically according to the manufacturer's instructions.

Ensuring proper drainage around outdoor plastic furniture and fixtures can help to prevent the accumulation of water and the growth of mildew and algae. Avoid placing plastic furniture in areas where water tends to pool or where it is constantly exposed to moisture. Regularly clean gutters and downspouts to ensure proper water drainage.
