I have an olfa and love it. Since it can be washed/soaked in water (Olfa's love water) the self healing mats. I just put mine on the dining room table on top of a towel and used a small amount of dish detergent and water and a soft veggie brush and lightly scrubbed and then clear water after that. Let it dry. Used a cutting mat sander and went over it and it's like new.
