In most teak cleaners
Part A is usually a caustic such as TSP (TriSodiumPhosphate)
Part B is usually oxalic acid
You can buy these in a hardware or paint store at a FRACTION of the
cost from a 'boat store'.

Most caustics will dissolve the oil from you skin. Oxalic will rapidly
absorb through your skin, then accumulate and do great cumulative harm
to you kidneys ... so wear gloves when working with part B

Part A will dissolve the UV destroyed (grey) surface layer of wood
cells but leave the 'fresh' cells intact. Part B neutralizes part A
..... and the excess part B bleaches the teak.

Does anybody know the ingredients of TEKA A and B?

I am wondering a bucket of what I should have ready to
quickly rinse off / flush away spills of TEKA A when
cleaning trim. (Soapy water? Vinegar solution? Sth. else?),
and also what protection is appropriate. (Rubber gloves?)

Thanks!
