How do I remove adhesive spray from my self healing cutting mat?
There's also a manual solution to this problem: Sticky tape.
It may seem counter-intuitive, but putting sticky tape on the mat and pulling it back off has a chance to pull the adhesive residue off as well. The glue on tape bonds with the adhesive residue on the mat. When you pull the tape off, the adhesive has only 2 choices:
either stick on the mat or stick on the tape. If the glue on the tape is strong enough (like duct tape or wire insulation tape) it will pull the adhesive away from the mat.
To do this, cut a strip of tape roughly as long as your hand is wide. Hold both ends of the tape together, sticky side out. Now dab the tape onto the mat and pull it away again repeatedly. If this methods works, you'll notice the adhesive residue on the tape. Once the surface of the tape is covered with residue so much that it doesn't stick well anymore, discard the strip of tape and cut a fresh one.
