I use a white eraser on it's flat side to clean my cutting mat after I have been cutting squares of batting on my mat . The fibers get stuck in the mat ! I rub the flat side of the eraser over the surface and the fibers just roll up and the mat is fuzzless again! I would NOT use a pink eraser as it may leave pink streakes .

thank you for sharing your tip with us (also one of those nylon scrubbers work)

That is what I use a nylon scrubber I got a couple with the little handels on them and keep it on the cutting table
