Teak wood

[nipper]

I have always taken all teak off the boat. Then apply the teak cleaner with a stiff brush, let it sit for a bit, then power wash it off. Comes out looking brand new. Then sand down any nicks/scratches. Its very important to let the teak dry for several days. Then I use Cetol. It is expensive (around $35 a quart) but a quart goes a long way. 2 coats of Cetol should do it. The cetol will last for years.
