We often are asked by our customers, how they can clean our resin wicker patio furniture. Well, first off, the materials used are very durable and resistant to the elements. The aluminum used for the frame is rust-free. The wicker itself is made from resin fibers and again, water and UV resistant.
So, you can simply hose the furniture down if you have tree debris or bread crumbs stuck in there. Loosen heavy dirt by using a soft brush, then vacuum it off.
In addition, you may want to cover the set when not in use for a longer period of time, e.g. for winter. You will prevent dirt from collecting on your outdoor furniture and keep it easier to maintain.
