I am curious, can any one tell me what the active ingredient(s) is in the Diggers Stain and Rust Remover, is it only Oxalic acid and what concentration? I am a little concerned it may be corrosive or set up dissimilar metals for corrosion. I have never used it.
I just found a MSDS for a similar Oxalic Acid product, it can be 7% to 18 % Oxalic Acid. Also it is very corrosive Class 8 and also very dangerous to eyes, so be careful. I would also lookout for it causing corrosion especially if it gets washed behind checker plate or in cavities and in contact with bare steel, aluminium and zinc.
