I have green Olfa cutting mats and I just cleaned them but don't feel like I got them really clean. I wiped them off with a rag, then used a lint roller (got tons of thread, fabric, dust bunnies) and then a clean wet rag. I feel as though there is a better way and was hoping someone could tell me what I could do differently. I am cutting Kona solid white fabric and am so afraid of it getting dirty. Any help would be greatly appreciated. Thanks in advance!
