Do not put teak oil on your teak furniture.

Most people put teak oil on their teak patio furniture because they want to preserve the golden color and prevent the teak from developing its gray patina. Not only will the oil darken the color by a few shades, but it will also, if not constantly maintained, attract mold and mildew. Teak oil turns your teak furniture from an easy-to-care-for piece of outdoor furniture to a high maintenance hassle.

* I should mention that if you have your own yachting crew or a house maintenance staff that can reapply the teak oil every season and keep a watchful eye over it, then you can ignore this advice.
