An effective all-purpose cleaning solution for outdoor wicker furniture is 1/4 cup of liquid dish soap and two cups of warm water. Wipe the wicker with a soft cloth or sponge, then rinse away the soapy suds with a garden hose. For mold and mildew removal, add one cup of white vinegar to the solution.

Because your chairs are having your chairs are having white spots come through you may have to spray paint your furniture

Might I suggest covering an old real hair brush, or soft scrub brush with either and old sweat sock or wrapped in microfiber. The bristles won’t scratch but will give you some gentle scrubbing power where it’s needed, between the “strands”.
