Seeing greenish mildew or algae spots on your recycled plastic park bench? Don't worry - this common outdoor issue is easily manageable with some simple cleaning techniques. Recycled plastic furniture is prized for its durability and sustainability, but like any outdoor surface, it can develop organic growth in damp, shaded conditions.
For light to moderate mildew or algae, start with this effective DIY solution: Mix equal parts white vinegar and water in a spray bottle. Vinegar's natural acidity helps break down organic growth without harming the plastic. Spray the solution generously over affected areas and let it sit for 10-15 minutes. Use a soft-bristled brush to scrub the surface, working in circular motions to lift the stains. Rinse thoroughly with a garden hose.
For tougher stains, create a paste using baking soda and water. Apply this paste directly to stubborn spots and let it sit for 20 minutes before scrubbing. Baking soda acts as a gentle abrasive that won't scratch your bench's surface.
When dealing with persistent growth, consider using oxygen-based bleach (not chlorine bleach, which can damage plastic). Mix according to package directions, apply to the damp bench surface, and allow it to work for 15 minutes before scrubbing and rinsing.
Always test any cleaning solution on a small, inconspicuous area first. For routine maintenance, simply washing your benches with mild soap and water every few months can prevent future buildup. Proper cleaning will keep your recycled plastic benches looking fresh and beautiful for years while maintaining their eco-friendly benefits.
