Hi sudek, I think you can use a stronger dilution of peroxide (15% or even 50% - but peroxide is kinda DANGEROUS at that dilutions, it may BURN your skin and stuff, therefore BEWARE! I'd go for the other SAFE way...) and add some more to fully convert iron(II) to iron(III) in your sensitizer solution w/o diluting it too much. I think adding just enough peroxide (not more than enough) will totally revive the solution w/o compromising it. BUT, I'd really prefer to purchase dry FO and mix a fresh iron solution. Mix small batches that you'll use up within a couple of months max...

mitch, sudek's problem isn't bronzing, it's the other way around.

Regards,
Loris.
