Photopolymer is a plastic that goes through physical and chemical changes when exposed to light.

You may use your Stampin' Scrub (126200) and Stampin' Mist (102394) just as you would with any stamps. If they ever get dusty or lose their stickiness, you can wash them in mild soap and water. If you use them with Stazon, you can also use Stazon cleaner (109196) on them. But, use it sparingly and make sure you do not leave traces of the cleaner on the stamps after cleaning.

Photopolymer stamps are more prone to staining. Basic Gray and red inks seem to be the worst. Make sure you clean your stamps promptly after use to avoid any staining or damage.
