Depends on how You seek to maintain the teak AFTER getting it clean?
If "A", I'd use "purple stuff" a green citrus based product that leaches enough of the oil
from the wood that a following a reasonable sanding
w/no finer than 100grit & wipe down with tack cloth, You're ready to begin.
If "B" I'd use "Simple Green", less oil
from the teak leached out, also does a great job, a 'green' product as well.
Both should be given a few minutes to work, have water
available for rinsing, and Scotchbrite Green pads are the ticket, along with rubber gloves (especially for the 'purple stuff', as it leaches the oils from Your skin as well...You'll be peeling like a snake the next day otherwise).
Whatever you do, DON'T PRESSURE WASH the teak if it can be avoided. Teak is a SOFT wood and pressure washers (especially on boatyards) are notoriously very high pressure rated and not "adjustable". They'll drive the soft wood between the grain right out of Your teak; once it's gone, it's gone forever. Both products are safe for gelcoat
as well, which should be a consideration for any other product as well.
Any "boat soap" will do the job too, just more "scrubbing" and less "almost instant" results.
