Dust the woven seat with a natural-bristle brush or vacuum it with the brush/hose attachment. Blow dust out of the nooks and crannies with canned air.
Wash the furniture with a sponge dampened with soapy water. A soapy toothbrush cleans the weave. Wipe the cushion dry immediately. Let the seat air dry overnight before painting.
Paint the woven seat with a thin coat of spray lacquer. Keep the spray can's nozzle 10 inches away from the seat. Paint it in even rows with long, steady, side-to-side movements. Overlap each row slightly.
Let the layer dry for time recommended by the lacquer's label before handling the cushion. Add a second coat if desired after drying. Do not let anyone use the seat for at least 48 hours.
