Hello from Betty
Thanks for the quick reply...it was the warm & natural that got stuck in the mat so I will see what helps..you gals are great..I'll remember you when I have another problem...Happy Quilting

That's funny, just this week I had to clean the warm & natural off of my mat. I wiped it first with a damp rag & after it dried I used the lint roller, then the damp rag again. It worked great. The batting really got stuck in those grooves.

I wondered what Warm and Natural was. Now I know. I've never cut batting on my mat or with a rotorary cutter. I just use scissors for that. However some fabrics can gum up a mat too.

Several years ago I bought some sandpaper called jewelers cloth. It's very, very fine grit and I use it to clean off all that gunk that gets caught in the cracks. It's like whet stone used to sharpen knives. Check at Home Depot or Lowe's or Ace Hardware.

If I am just trying to remove the little pieces of scrap materials, then I a 6x6 piece of batting. I simply just swipe it across my cutting board and it picks up all the pieces of materials/loose threads. If it needs to be cleaned, then I use a soft rag dipped in water/vinegar solution mix and wipe over my board. You might tend to think this would make the board smell like vinegar but it doesn't!! :)

There is a little tool like a sander,I haven't looked in a couple yrs. but Clotilda had them for sale. My sister bought one and I used it on my self healing cutting board and it worked pretty good. Also on the plate the needle goes thru. forgot what it is called :oops: But you take it off if you have a drop in bobbin. :-D I f your needle ever hits the plate and you have a little gouge,Ihave done this before when I was learning,my needles were wrong size or I had shifted the needle position left it there the needle would hit plate and gouge a little nick. Clotildas also had some kinda of sand paper for metal and it smoothed out the nicks super good. I keep a small sheet of it on hand just in case. But am now more careful when I am adjusting from one thing to another. BillsBonBon

Through a chance attempt, I have found that by rubbing a fine sandpaper all over the mat (that is the white one) it is almost as good as new. As a tole painter, I understand how fine sandpaper will smooth wood so I thought, what the heck, and gave it a try. It is wonderful! Does a great job and DOES NOT remove the lines or printing. Removes all those annoying burrs too.

a board scraper.

I use a plastic pot scraper I found at (I think it was ) Bed Bath and Beyond.

How about some poly batting. It surely picks up a lot of lint and threads on mine, dust too.
