You can also buy soda ash from a pool supply store, used to increase
the ph of pool water.
Both are sodium carbonate. Baking soda is sodium bicarbonate.

Its sort of like baking soda but is much stronger and has a high pH.
You should wear gloves, make sure it doesn't sit for too long, that
is, rinse pretty quickly. The instructions say not to use on
fiberglass or aluminum, but I never saw a problem. Old teak turns
golden with just a light scrub, and them you hose it off.

Please pardon my ignorance, but what is washing soda ?

Thank you,

Washing Soda works surprising well - once I discovered that I never
used another product on unfinished teak. A little light scrubbing
(and I really mean just a little) and the teak turns golden brown.

Of course, then I saw the light and bought a boat with no exterior wood!
