Of course, prevention is better than cure, so waterproof furniture covers for your wooden furniture keep tables and chairs safe from their biggest dangers sun and rain. The first thing to do when restoring your outdoor furniture is to clean it with soap and water. Be sure that the surface is dry before doing any more work. A toothbrush and toothpaste work well at removing many stains or marks on the furniture! If your furniture has a finish to it, clean it with mineral spirits on a rag. Wipe off the excess spirits and then brush on an outdoor varnish or a coat of brightener. Let this dry before treating the wood with teak oil (made for all types of wood) to prevent weathering. This treatment will not only restore your furniture, it will also feed the wood and give it a rich finish.

You should avoid standing wood legs directly on grass as the moisture from the ground may rot untreated wood over time. If you can''t avoid this, at least give wood legs some extra protection by standing table and chair legs in saucers of wood preservative for several hours, so that as much solution as possible gets soaked into the wood. When cleaning up wet spills, be sure to dry the furniture completely, never assume that the sun will do it. The wood may take all day to dry out, and in that time, airborne dirt such as pollen may have formed an invisible yet sticky film on your table.
