The interior of our 1985 Catalina-30 has teak that has never been varnished and we've never put teak oil on it, a former owner may have, but that's been 10+ years ago. It looks ok, but every spring we spend too much time cleaning the mildew off the teak. We don't mind cleaning the fibreglass surfaces - that goes quickly and it's easy to do. But the bleepin teak seems to take forever. The question I ask is a simple one: what is the easiest and/or best way to seal the teak to minimize future "extended" spring cleaning? We're not looking to creat more brightwork to have to refinish every few years - so we don't want the high gloss "Bristol" look just nice smooth teak surfaces that are not "mildew farms."
