Nordicare Teak Oil (525 ml) - Wood Oil for the Entire Indoor Area - Revives the Original Color of Wood - Premium Teak Oil Wood Care Oil with Stain Protection - Natural Silk Matt Finish-Made in Denmark

I have always used "teak oil" sold for the care of Scandinavian teak and other wood furniture. Periodically gently scrub the piece with 4-0 steel wool dipped in the oil (removes grime and spills) and wipe off the excess with a soft cloth. That's all it takes.
