Had blowboater on the GB over the weekend. He commented that he uses a
dishwashing powder detergent called "Electsol" to clean the teak decks on
his 37' sailboat. The deck on our GB has darkened considerably despite
regular washings with regular boat soap, so I decided to try the Electsol,
per his instructions.

I saturated the deck with fresh water, sprinkled a very small amount of the
Electsol powder on it and then scrubbed away with a coarse boat brush. When
I rinsed it, I couldn't believe the amount of black "mud" that was washing
away.

The next morning, after the deck had dried, the teak looked brand new and
several shades lighter, other than a few darker places that I had missed
with the brush. Don't know if it's bad for the deck or not, but it works
better than anything else I've used other than a pressure washer (which I
use only on teak furniture .... never on a boat deck). According to the
sailboater, Electsol and other types of dishwashing detergent have a very
small amount of bleach in it ... not enough to damage the wood.... which
apparently makes a big difference.
