How do you clean wicker funiture?

Start with something like Fantastic, or some household cleaner. Spray it on the wicker, and blast it with the hose. I don't know where you live, so I don't know if you have strong sun this time of year. Let the wicker dry in the sun, if you can, or wait till the summer to clean the furniture. It must be dry completely before you store it away.

Is it white wicker? If it has been discoloured due to time and weather, then it will not be possible to "restore" it with cleaning only. It will have to be cleaned, dried, then repainted.

To clean dirty wicker that's made of bamboo, rattan, or willow, brush off or vacuum as much of the surface dirt as you can. Then wash it with a soft brush and soapy water to which you've added one or two teaspoons of ammonia. Rinse well and let the piece dry outdoors in the sun.
