Do you have one of those handy 3M lint rollers laying around? I was cleaning the lint off my coat the other day and I had a light bulb moment... this might just work to clean up those little "leave behinds" on my cricut mat. You know those nagging little tiny pieces of paper that are a pain to remove? Try this method, I think you'll like it. I think you can get a 5-pack of these for about $15 at Amazon and it might be even cheaper at Costco or Sam's club when they have them.
