Keeping your thermoplastic-coated outdoor benches looking great for years is easier than you think! This durable coating is designed to withstand the elements, but a little regular care goes a long way. Here’s your simple guide.
For routine cleaning, all you usually need is mild soap and water. Mix a few drops of dish soap in a bucket of warm water. Use a soft cloth, sponge, or a soft-bristle brush to gently wipe down the entire bench. This removes everyday dirt, pollen, and bird droppings. Always rinse thoroughly with a hose or clean water to remove any soapy residue, as this can attract more dirt if left to dry.
For tougher stains like mildew, tree sap, or grease, a stronger solution may be needed. A mixture of white vinegar and water (one part vinegar to three parts water) is excellent for mildew. For sticky residues, a little rubbing alcohol on a cloth can work wonders. Always test any cleaner on a small, inconspicuous area first. Avoid harsh, abrasive cleaners, steel wool, or power washers, as these can damage the thermoplastic coating's protective surface.
The best care is preventative. During harsh winter months or long periods of non-use, consider covering your benches with a breathable, waterproof cover. While the coating is weather-resistant, this extra step minimizes exposure. Periodically check for any scratches or chips in the coating. If you find any, a touch-up with a matching thermoplastic paint can prevent rust and protect the underlying metal.
With this minimal, consistent care—simple cleaning a few times a year and prompt attention to spills—your benches will remain a beautiful, low-maintenance spot to relax in your garden for a long time.
