1. WPC is a durable and strong material. You don't have to maintain it like solid wood flooring. It will stay like new for a long time. So it can eliminate your maintenance costs. 

2. If there is dust and other stains on the wpc floor. Just use a brush to clean them. For wpc fence, you can wipe it with a damp cloth.

3. How to clean dirt like grease stains after cooking? If you are using co-extruded WPC flooring, you can simply rinse it with water, as co-extruded WPC has an outer layer to protect it from oil contamination. If you use classic wpc flooring, you must clean it with detergent.
