teak swim platform

Power wash, strip and sand as needed. Boiled linseed oil is all I've ever used.

Mine had a finish on it, sounds like the same thing you had. I went with a stripper and scraped off what was loose. Then went with the power wash, let it dry out for a couple of days in the sun. Last, same as everyone else, a lot of coats of teak oil until it wouldn't soak in any more. Mine turned out looking very nice.

Removing each board will probably make getting all the poly off more complete, just remember how to put the watch back together.

Thanks guys! Do you suggest using any sort of stripper on it?
Or do you think that would damage the teak?
Also was thinking about removing each board.
Or is that over kill?

Welcome!!!!You are heading in the right direction, poly is bad news. Strip and a light sand, not too smooth or it gets slippery again, and then lots of coats of teak oil, first ones a day apart, then every few days until it stops soaking in. I use a course sponge to apply, there is less waste and dripping. I keep the sponge in a zip-lock in the garage and give it another coat about three times a summer. I touch it up on the boat, but removed it for the initial work to keep the teak oil off the fiberglass, and allow coating all sides.
