I used to use 30% H2O2 for digesting epoxy. That stuff was VERY reactive.

So where do you get 30% H2O2?

That’s a new one on me. I never would have thought of it being useful on polymer type materials, at least cured ones.

I mostly used 30-40% in a process for cleaning gold jewelery. Had to combine it with another chemical that is also now highly regulated, but it worked like magic.
