I have read debates about this on many sites and many magazines...so I ask Queen Kat Designs .
They told me ...
"Hi Tina. Yes, it's ok to use Stazon on clear stamps (real acrylic stamps, not the pressed plastic) It is NOT ok however to use Stazon Cleaner on them. The cleaner will eat your stamps faster than you can buy a new set! The cleaner will break down the chemicals and your stamp will turn into mush. I found out the hard way with an expensive CTMH set and when I started making stamps, I experimented with it. HTH."
So I figured I should pass this on.
