How to Make Cricut Mat Sticky Again - by Laurie. (Works for Scan-N-Cut mats too.) Wash the mat with warm water, foaming soap, and a kitchen scrub brush. Let dry. Sometimes this is all you need to do. If the mat still isn't sticky enough, mix 1 part Alene's Tack-It Over & Over with 1 part water. Use a foam brush to apply all over the grid part of the mat (not the edges). Let dry an hour or more. Pat it down with clean hands to condition it so that it isn't too sticky.
