For the most thorough cleaning, and to preserve and protect your clear stamps, use Technique Tuesday Clear Stamp Cleaner. Our cleaner contains no harsh abrasives or alcohol that can damage your clear stamps. Use it on the back of the stamps to restore the stamp's stickiness. It can also be used to clean the clear blocks and the back of the storage sheets where the stamps are stored. It is packaged in a 2 ounce spritzer bottle and works best when spritzed on the Technique Tuesday Clear Stamp Scrubber.
