Homebrew PCBs

Another thought is possibly oxi clean . it is basically hydrogen peroxide although maybe a bit stronger than the 3% stuff you buy at the drug store

Read the MDS. It is pretty safe stuff. About a million years ago I was a Lab Tech and HCl was used to wash ink off our hands.
Beauty shop peroxide is about 30% and over $30 per gallon. The drug store stuff works and $1 per Qt. I wash all wounds with the $1 peroxide and some people use it for mouth wash.
It also leaves bleach dot on you clothing.
