What cleaning agents are safe for maintaining WPC outdoor armchairs without causing degradation?

Maintaining WPC (Wood Plastic Composite) outdoor armchairs requires careful selection of cleaning agents to prevent degradation. Harsh chemicals can damage the material, so opt for mild, non-abrasive solutions. A mixture of warm water and mild dish soap is highly effective for routine cleaning. For tougher stains, a diluted vinegar solution (1 part vinegar to 3 parts water) can be used without harming the WPC surface. Avoid bleach, ammonia, or abrasive scrubbers, as they can break down the composite material over time. Rinse thoroughly with water after cleaning to remove residue. Regular maintenance with these safe agents will keep your WPC armchairs looking new and extend their lifespan. For added protection, consider applying a UV-resistant sealant annually. Always test any cleaner on a small, inconspicuous area first to ensure compatibility.
