Restoring wood furniture means cleaning off the grime from the top of it to start with. You can easily do this with plain water and soap, but weathered wood takes a bit more elbow work. You can use teak oils or natural oils to condition your wooden furniture before putting them out for the summer. These treatments help to weather-proof those pieces against rainfall. If the finish is dull, you might need to resand and reseal them. This job is labor-intensive, but it's well worth the final look you get. You can redo the varnish on tables that just need that extra coal of sealant on them to protect them from the elements.Metal Furniture
The first thing you'll need to do with metal furniture is a warm water rinse with soap. Rub it down thoroughly to clean it, then rinse off the suds. Let the furniture dry completely and if there's still visible dirt, redo the process. Glass-top metal tables can benefit from a solid window cleaning solution. If it got really dirty in storage, do a first-pass with a paper towel to get the heavy gunk off before starting on it with your window cleaner solution. If you really want to seal and protect it from the elements, a thin coat of car wax is a brilliant solution to look into.Resin Furniture
Resin is resilient and doesn't pick up grime that easily, making it one of the most straightforward bits of furniture you'll have to clean. You'd use the same wash and rinse process as you did with your metal furniture pieces. A bristle brush (preferably soft) and some warm water with dish soap added in is all you need. Avoid harsh chemicals since those could damage the finish on your resin furniture. If you have extremely stubborn stains, using a melamine sponge will get them out quickly.Continual Care is Key
if you want your Franklin & Ben furniture pieces to keep their finish through their outdoor life, regular care is critical. Most people think that outdoor furniture is indestructible, but that's far from the truth. They need good care as much as any other furniture you have. Wiping down your furniture regularly with a dry cloth is the start of upkeeping it. If you don't take care of it, it'll succumb to the climate and weather just like any other furniture left outside.
