...AND regular maintenance to keep looking good, due to exposure to the elements. The MSL article, called "Freshening Up Outdoor Furniture", breaks down the info into 5 frequently used outdoor materials.
We pulled a few good tips from the article for cleaning & maintenance from each section:
Wicker: Clean with a dust brush vacuum attachment or a dry paintbrush followed with a mild soap solution; a recipe is included in the article - 1 cup of Ivory to 1 gallon of warm water.
Wood: To remove rust stains or bird droppings, use fine grit sandpaper.
Restain or seal every 1-3 years.
Metal: After cleaning and touching up paint, apply a coat of paste auto wax to help protect the finish.
Fabric: Clean outdoor upholstery often, as some fabrics can be discolored by suncreen.
Plastic: for tough stains or mildew: make a solution of 10parts water to 1 part bleach.
