I appreciate the tips. Thank you for all of the advice on cleaning my mat. I'll have to give these suggestions a try and see which one I like the best.

I wish I had known this in July! LOL I have the heavy glass from our old Clear View windows that were in the farm house. I use them for shelves at our quilt show. We put 2x4's under them and can store extra pies there so that we can see them as we serve the pies that are lined up on top of the glass.
I also have written a "Tip" for our quilt club list that includes: Never let your cutting mat near anything hot; that includes your iron, hot water, your coffee cup, your hot car nor the sun from your window.

I have gently used very, very fine sandpaper with a block of wood, with paper wrapped around it. I have also used those rubber scrubbers that do not scratch the surface.

The pot scrubbers crocheted from nylon net do a great job of removing the fuzzies from a cutting board.

I simply clean my mat with my lint roller. That works just fine and I seldom need to use that. What are you guys cutting that make such a mess?

Thanks for the info, quiltstringz.

I use a mat smoother soak it down in the tub

I use the sticky lables that come on fat 1/4 's to rub over and pick up the threads and fibers that get caught in the mat. For a bigger than normal , I use a nylon pot scrubber, and soak in water.

Thanks for the great advice.

I do as susie-susie-susie does....I have a sticky lint remover that I roll over my mats when they need cleaning...they work great!
