Soap (Dawn), water, and a soft brush should get it nice and clean. Many folks use an oxalic acid based teak cleaner but it is harsh and care should be exercised to rinse quickly and very well as soon as the teak is clean. Then, rinse again.
Finished or clean unfinished teak and other bright work (mahogany) will look beautiful for a long time if it is protected from the elements and especially from the UV of sunlight as much as possible.
