Cleaning an outdoor bench made of recycled plastic is surprisingly simple—if you know the right approach. Unlike wood or metal, recycled plastic is durable and resistant to rot, but it can still become dull or scratched if you use harsh tools or chemicals. Here’s how to keep it looking like new without causing damage.
Start by rinsing the bench with a garden hose to remove loose dirt, dust, and debris. This step prevents scratching when you start scrubbing.
Next, mix a gentle cleaning solution: warm water and a few drops of mild dish soap (like Dawn or any biodegradable brand). Avoid bleach, vinegar, or abrasive cleaners, as these can dull the plastic's finish or cause discoloration over time.
Dip a soft sponge or microfiber cloth into the soapy water, then gently scrub the bench in circular motions. For stubborn stains—like bird droppings or tree sap—let the soapy water sit for 5–10 minutes before wiping. Never use steel wool or hard-bristled brushes; they will leave permanent micro-scratches.
Rinse thoroughly with clean water from the hose. Make sure no soap residue remains, as it can attract more dirt when it dries.
For an extra touch, you can apply a specialized UV-protectant spray designed for plastic outdoor furniture. This prevents fading from sun exposure and keeps the bench looking vibrant for longer. Just spray on a dry bench and wipe with a clean cloth.
Finally, allow the bench to air dry completely before using it. Avoid leaving it in constant standing water—if your bench is near a sprinkler or pond, tilt it or move it occasionally to prevent moisture buildup on the base.
By following these simple steps—soft cloth, mild soap, and a gentle hand—you can keep your recycled plastic bench clean and beautiful for many seasons. No harsh chemicals, no damage, just a fresh outdoor space.
