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?
Paint store, or paint dept at Home Depot or Lowes.
Toxic stuff, so read and heed the warnings.
Entirely different mode of action from chlorine bleach others are
suggesting.
