You didn't bring the outdoor furniture inside for the winter, or even cover it. Now, your chairs and patio table, even the umbrella, look plug ugly. No need to panic, though. Just give them a good cleaning, maybe even new paint, and they'll look fresh as spring.
WICKER
To clean woven furniture, you'll need to get into and around those intricate weaves. And that requires a variety of brushes -- a new, rather than used, toothbrush (stiffer bristles); a small paintbrush with bristles cut down by half, to make them stiffer but not sharper; and a bristle brush with medium bristles. Some experts recommend sharpening a dowel to pick out bits of dirt and debris, but the best tools are already sharpened -- the wooden skewers used to make shish kabobs.
After you've gotten the gunk and grime out of the weaves, vacuum a wicker piece thoroughly. Then wash, using minimum amounts of a solution of two tablespoons of ammonia to two gallons of water. Clean in sections from top to bottom, then dry the wicker quickly to prevent it from warping. Lay the piece on a clean canvas dropcloth; tip it so the tighter weaves are on top and the looser on the bottom, so the moisture runs down and away quickly. Keep the weaves straight, so they don't shrink.
If mere cleaning isn't enough, sand and repaint (follow manufacturer's suggestions). Depending on the piece, spray paint may give better coverage in less time.

Grab a plastic scrub brush and dishwashing detergent at full strength and then scrub, scrub, scrub. Rinse thoroughly, then let dry.
