I have read that deck cleaners are basically Oxalic acid. Being the
cheap-skate that I am does anyone know where can I buy Oxalic acid to
clean my deck?


Oxalic acid is a wood bleach and is toxic-posinios. Requires special
handling.
I would not recommend it.
Go to a paint store they will carry a cleaner which I believe is
called Tri-sodium
Sulphate or phosphate. They will know which. It is an exellent cleaner.
