I'm looking into anodization, and all the people doing it seem to have sulfuric acid as their first choice electrolyte, while others use sodium metabisulfate. Having simple access to exactly neither of these, I was wondering.
- Why is sulfuric acid important?
- Can I use more accessable (and safer) electrolytes such as vinegar or sodium bicarbonate instead?
- How much of a difference would it make?
