Someone asked me if I have used Simple Green on a cleaning pad or just directly onto my stamps, and I have only used it directly onto my stamps not a cleaning pad. I found that the cleaning pads when used in the past (not with Simple Green), that it would leave little fuzzies on the stamp and that is just irritating. However, once I do spray onto the stamp I let it sit for a second or two then take a soft bristled brush to the stamp while running under slightly warm water. Hope this helps :)! Will let you know how the Simple Green wipes work out :D!
