How to Clean Dirty Poly Lumber Furniture

Poly lumber furniture is made from High Density Polyethylene (HDPE), which is a product with pores, and on certain colors like white or yellow, if dirt settles into the pores it is almost impossible to remove. This is part of the nature of the material and is not considered a manufacturer's defect.

To remove dirt from your poly lumber furniture, spray the furniture thoroughly with Super Strength Mean Green cleaner and allow it to soak for approximately 5 minutes. Scrub the furniture using a brush with medium-stiffness bristles. Rinse furniture with warm, clean water.

If this doesn't clean the dirt completely, again, spray the furniture with Mean Green cleaner and wash the furniture extensively using a pressure washer. Do not get the tip of your pressure washer to close to the furniture, or it may actually tear into the material. Keep the pressure washer approximately 8-12 inches away from the poly material. You may need to repeat this action several times, but this may help in cleaning your furniture.

Poly lumber furniture will not rot or splinter, and it contains an added UV protective agent to resist fading. Poly furniture is not affected by most corrosive substances, and will not promote bacterial growth. To maintain the beauty of your furniture, clean it regularly with soap and water. Use only nonabrasive soaps. Do not place flower pots or any items on furniture that will leave stains. Do not place hot items directly onto furniture to avoid melting. All hardware is stainless steel and virtually maintenance-free under normal conditions. However, in coastal areas, hardware will need regular rinsing with fresh water to eliminate rusting. If you properly care for it, you will be able to relax in your fine piece of poly furniture for many years!

You can leave your furniture out in the winter and they do not need to be covered, but there may be some heavy cleanup in the spring. Snow sometimes leaves residue when it melts that will leave a dirty film on your furniture. The choice to cover or store the pieces is yours. It isn't necessary as the pieces will not be harmed by the weather, but they will get dirty.
