The process simply involves heating the peroxide to the point that bubbles and mist appears, and let it go until a 50% volume reduction is achieved (for 6% solution).
There is a video somewhere on YouTube that shows the simple process.
Keep your H2O2 in a closed bottle, and as full as practical, since peroxide quickly gives up its extra oxygen molecule, and looses strength, eventually turning back to plain water.
Thanks

Toner Transfer Paper Problems
hi,
I use a flux I got at radio shack,I use just enough to coat the copper on the board any excess gets the board sticky,I sometimes heat the board with a heat gun this levels the flux and dries it out and it's not sticky anymore now the traces can be soldered and won't corrode and it's cheep,lol.
