We should also recognize that it is not approved for use in many areas. Oxalic acid is indeed an oxidizing agent and it must be handled carefully. It is not for human consumption. Oxalic acid dihydrate is the stable crystalline (dry, powder) form of oxalic acid (incorporating 2 water molecules for each molecule of oxalic acid in order to make a stable crystalline form) and thus is the form that is most commonly available. Anhydrous (no water in the crystal) oxalic acid could possibly be procured but has NO particular advantage over the previous form (and it would likely be more expensive). Oxalic acid is in the LEAVES of the rhubarb plant (which are NOT consumed). Oxalic acid is an oxidizing agent that is commonly used to "bleach" out rust stains, for example but is not a danger if used properly. One should also consider whether this is legal and ethical to use in their own local area as well. Off-label applications could potentially be dangerous and should not be pursued with the exception of research institutions charged to do so.
