What takes off that 'residue' left behind from the toner using inkjet paper?

2006-02-11 by braincambre500

Hello all,

My toner method is coming along real fine, and want to thank all the
ones who have taken time to help me through the process.

I now got it down pat!

The only thing of concern is that filmy coating left behind on my PCB,
after I scrubb off the inkjet paper from the board. I tried
alcohol/WD-40/household oil/and even an eraser...now the eraser works
pretty fair...but I sometimes scrub off bits of the toner also. I am
wondering what substance is this 'filmy' stuff made of? That way, I
can buy a certain chemical that will attack it.

Any has knowledge in this area?

Thank you again for all the help!

Patrick
