Teak oxidizes and turns gray quickly, and while some people find this attractive, others prefer the honey-tan hues of fresh teak. You can often restore weathered teak just by sanding it, but if the discoloration goes deep, or if there is a surface layer of mold, it may be easier to scrub it with a cleaner.

Can you sand teak indoor furniture?
To refinish teak, sand it down with an orbital sander. This uses fine-grain sandpaper and will gently sand away the old gray layer. Don't push down too much with the sander as this can damage the furniture. You can also use small pieces of sandpaper to sand down teak by hand.Jan 8, 2010
