Keep wicker furniture away from harsh weather conditions. Bring it inside if it is raining as excess moisture will cause molding to occur.
Wash wicker furniture with warm water and a mild detergent every few months. Allow to dry outside on a breezy day. Disregard this step if you own wicker furniture made of paper fibers.
Create a mixture of bleach and water to prevent darkening of furniture. Use 1 part bleach to 3 parts water. Allow furniture to dry completely before sitting on it.
Dust wicker furniture on a regular basis. Brush hard to reach areas with a toothbrush, and use the brush attachment on your vacuum to suck away dust from entire furniture piece.
Use seat cushions to prevent discoloring in seating areas. Match seat cushions to decor of your home.
