WPC Maintenance
Is your decking maintenance-free?

COOWIN decking requires far lower maintenance than wood decking, but does require some maintenance to keep it looking good throughout the years, much like washing your car. So a periodic cleaning with a jack wash and soap water is recommended, which is necessary to maintain the beauty of your deck.

Is your product stain-resistant?

All COOWIN composite products are stain-resistant with warranty (see COOWIN warranty for details). Most stains commonly encountered such as mustard and ketchup will wash away easily within 7 days. More stubborn stains can be washed off with the mild cleaner.

Dose your decking need regular maintenance?

COOWIN composite decking is designed for a low-maintenance experience. But to keep your deck to look great, you are advised to clean your deck at least twice a year by jack wash with mild soap and water.

How do I clean my deck?

For general cleaning, sweeping with broom, or jack washing with mild soap water works. For pollen, organic debris, dirt or stains, mild household detergent dilluted with water is recommended. Always keep your deck from chemicals.

Can I use salt to melt ice on my decking?

Most products with calcium chloride or rock salt can be used to melt ice and snow on COOWIN composite decking. These products may leave a white residue which can be cleaned by brushing with mild soapy water. Care should be taken when removing snow or ice from your deck to avoid damaging the deck surface.

We recommend to use plastic shovels, instead of metal or shar edged tools. Do not use ice melt with an added colorant, for the dyes can stain your composite decking. Never use sand on COOWIN composite decking, because sand abrasion can grind into the decking and permanently damage the surface.

Do I need to place something on furniture legs to protect my decking from scratches?

Yes. We recommend to use protective plastic, rubber, or felt leg pads on furniture and other items to help protect the surface of your deck. COOWIN composite decking is scratch-resistant, but these easy extra steps can provide additional protection.

What if my decking gets scratched?

In the same way that wood decking materials can get scratched, the surface of composite decking can also be scratched. COOWIN composite products are of superior scratch resistance, but not scratch proof. If scratches do occur, we recommend allowing normal wear marks to disappear gradually.

How can I prevent mold from growing on my deck?

To minimize mold on the decking, clean the deck periodically with at least twice a year . In some situations, you may need to repeat the cleaning process multiple times until you are no longer able to see any “shadows” of the spots on your deck while it is wet. You would also want to apply a mold inhibitor to retard future growth.
