Dry furniture until it has less than 15 percent moisture content (approximately three to five days in dry weather).
Remove loose dirt with a clean, dry cotton cloth or soft bristled brush.
Clean dry furniture using a stiff bristle brush and a mild wood cleaner. Let it dry overnight.
Sand in the direction of the grain with medium grit paper to open the wood's pores to allow for greater penetration of the oil. Follow with finer grits, if necessary, depending on the condition of the wood's surface.
Use a clean, dry cotton cloth to remove sanding dust.
Stir oil before, and occasionally during, application. If more than one batch is needed, blend together prior to application.
Once the wood is clean and dry, use a clean, dry cotton cloth, soft natural bristle brush, or lambswool applicator to apply the oil with the grain in even strokes. One coat may be sufficient, depending upon the product used. Refer to your product's documentation for specific coat instructions.
If multiple coats are suggested, allow the oil to dry a minimum of one hour between coats. Use fine or extra fine grit sandpaper to sand between dried coats, if necessary.
Let dry 24 to 48 hours, depending on the number of coats applied.
Use mineral spirits to clean brushes. Soak cloths in a sealed, water-filled metal container to prevent spontaneous combustion. Dispose of empty cans or unused portion in accordance with local, state and federal regulations.
Reapply every one to two years, depending upon sun exposure and wear.
