Initially I was trying that, but 98% sulfuric acid and 40% hydrogen peroxide needed like 3 days to etch plastic (with like 10 fresh "mixes"). Now I can try that

Initially I was trying that, but 98% sulfuric acid and 40% hydrogen peroxide needed like 3 days to etch plastic (with like 10 fresh "mixes"). Now I can try that with higher concentrations, would be great if It could lower temperature.
