Plastic lumber has become a popular choice for urban benches due to its durability and low maintenance requirements. However, proper cleaning and maintenance are still essential to keep your benches looking their best and extend their lifespan. Here's your complete guide to caring for plastic lumber benches.
For routine cleaning, start by removing loose debris with a soft-bristled brush or dry cloth. Mix a mild soap solution using warm water and a few drops of dish soap or a dedicated plastic cleaner. Avoid harsh chemicals, abrasive cleaners, or solvents that could damage the material. Use a soft cloth or sponge to gently scrub the surface, then rinse thoroughly with clean water. For stubborn stains like bird droppings or gum, use a plastic putty knife to carefully scrape them off before cleaning.
For deeper cleaning needs, create a solution of one part white vinegar to four parts water. This natural cleaner effectively removes tougher stains and mineral deposits without damaging the plastic. Apply with a soft brush, let sit for 5-10 minutes, then rinse completely. For mold or mildew in shaded areas, use a solution of one cup bleach per gallon of water, but test on a small area first and rinse immediately after application.
Maintain your plastic benches by performing routine cleaning every 2-3 months, or more frequently in high-use areas. Avoid using pressure washers, as the high pressure can damage the surface texture. Never use steel wool, abrasive pads, or harsh chemical cleaners that can scratch or degrade the material. To protect against UV damage in sunny locations, consider applying a UV-protectant spray designed for plastics every 6-12 months.
With proper care, your plastic lumber benches will maintain their appearance and structural integrity for years, providing comfortable seating while resisting rot, insects, and moisture damage that typically affect traditional wood benches.
