Wicker outdoor furniture can be cleaned using a hose or pressure washer on the lowest setting. Simply remove the cushions and spray off dirt and spills. If the wicker is especially dirty, use a sponge, mild soap and cold water to wash. Allow the furniture to dry completely. Then apply a paste wax to the frame to keep it shiny and water-resistant. Some types of wicker are weather-resistant, making care easier. Store cushions indoors and keep frames covered during the off-season.

Wooden outdoor furniture that's been coated with an exterior-grade varnish can be cleaned using soapy water. Be sure to completely rinse the furniture with clean water. Wooden furniture, with the exception of teak and cedar, should be stored indoors during the winter.

Aluminum, wrought iron and steel frames require cleaning with water and mild soap. Many modern metal frames are rust-resistant or rust-free. If your metal furniture isn't, use paste wax or naval jelly to keep it from corroding or rusting.

Resin furniture requires the least amount of care. Simply spray off with clean water and allow to air dry. If scuff marks are present, use a gentle abrasive to remove. Mildew can be removed using a mixture of 1 cup of bleach, 2 cups of detergent and 1 gallon of water.

Acrylic Cushions
Acrylic cushions should be removed from the frame before cleaning. Spot-clean using a sponge, mild soap and water. Rinse with clean water. To prevent mildew, allow to dry completely before using or storing. Some types of cushions are mildew-resistant, but if you have a problem with mildew, use a solution of 1 cup of bleach, 2 cups of detergent and 1 gallon of water to clean. Mix thoroughly and spray on the entire cushion. Allow it to soak for 30 minutes. Scrub with a sponge or clean rag. Rinse with clean water and allow to dry completely.
Cloth Outdoor Furniture
Machine wash canvas covers and hammocks on the gentle cycle. Add bleach for white items. Hang outside to dry. To avoid shrinkage, stretch back over the frame before the fabric is completely dry. Frames should be cared for based on the material. Store fabric furniture indoors during the winter.

Umbrellas require maintenance after being in storage. Covers need washing and umbrella frame joints need oiling. Wash covers using a soft-bristled brush, mild soap and cold water. Use a spray lubricant on the joints of a wire-frame umbrella. If you have a wooden-frame umbrella, use paste wax to restore its shine. Always follow the manufacturer's instructions when caring for your outdoor furniture. Keep the instructions in a safe place for easy access.
