We use Semco sealer than teak oil. We have been told that teak oil is actually not good for teak.

we used to oil our (indoor) teak furniture, then shed it all to our children setting up their homes, no idea what they do. our outdoor furniture we've let go to grey and its holding up great.

Be prepared with Teak furniture! Unless you like weathered, silver, gray old looking teak after a year, you will have endless hours of scrubbing and getting rid of mildew every year. NEVER AGAIN. Can't wait to get rid of my teak.
