I wipe uncoated teak with a terry cloth and acetone or lacquer thinner to remove oils. I turn the cloth frequently and use a new one if it gets discolored with oils. Never had a finish fail using these simple techniques.

I use Cetol natural and sometimes Cetol gloss. IMO, it's the easiest, most robust teak finish to apply. But I will admit to a sigh when I see the glass finish on a Hinckley's teak.
