I think the secret here is the acetone, (not a very nice solvent to be using in
close confines of your cabin BTW), it acts a degreaser and strips the
natural oils from the surface of the teak and lets the cetol get a 'grip'.

yep. The bleach water mix is to get the sanding dust off and to brighten the
wood a bit for better color. Acetone really drys out the upper surface and teak
is naturally oily wood. Works great, looks good and lasts and lasts.
Unless you're dumb like Doug!
