Scraperite Products
Scraperite double-edged plastic razor blades are great for scraping and cleaning wherever a metal blade would be inappropriate. Try some out, you'll be amazed how well they work. They'll never rust or corrode and they are non-conductive and non-magnetic. Not to mention you won't cut yourself... or anything else.
