We recently purchased a used 8 piece teak furniture patio set. The set is in great condition, slight graying. Did research online for refurbishing ideas. Too many differing points of view so decided to visit a teak furniture store. Harbor Teak is nearby our home so we made the trip a few hours ago. Store owner Justin was so helpful and knows teak woods very well. Justin focused on our needs and wants. We showed him photos of the teak furniture targeted for restoration. He walked us through steps to take, and steps to avoid. So glad we stopped in. Ended up purchasing teak oil, but will hold off on applying it after cleaning until springtime as suggested. Evidentially mold spores are attracted to oil in outdoor humid environments. Our newly acquired 8 piece outdoor furniture is too large to store indoors. Even with a patio roof, high humidity in Washington State during fall and winter is normal. We didn't see the yellow flag with snake mentioned in another review, but asked about it. Justin collects all kinds of flags, even old military flags with "don't tread on me" meanings. Coming from a military family myself, I got a kick out of someone misunderstanding the flags meaning. Just ask Justin, he has lots of interesting stories! read more
