This is what I found on the internet.
Heat – It is best to store self-healing cutting mats flat, not near heating or direct sunlight and not too cold as they may become brittle. The mats are heat sensitive. They will warp from heat and improper storage - keep them flat. Well I learned that the hard way: put a freshly filled teapot on the corner of a mat, which has never been the same since.
Cleaning – Use warm water and mild detergent. Avoid abrasive cleansers. A nylon net scrubber can be used to loosen any stubborn dirt. I always use a lint roller to remove lint and tiny pieces of fabric - not just on the mat.
The cut marks can be seen but only cutting in the same place again and again gives wider marks. But usually they last for years.
Thank you Mops, I will do what you wrote. I learned the hard way also that they need to be stored flat. Will the lint roller take the fabric fuzz out of the cuts? H&*.
Go to www.cutting-mats.net at bottom of page.Don't use anything that will scratch.
My dear, it sounds like you have some great answers and I wouldn't have known what to tell you - I just opened the question to learn - so here is a *4U. Love!
U have quite a few answers here dlmds. Mine is self healing & so far has no cuts in it. I have no idea how to repair one but notice one of the QTs says their is a tool so perhaps that will help u. *
Yes lbrow, I am going to check into it when I get to town (40 mile round trip for me). H&*.
I'm trying to remember what the tool is called, but it scraps the mat to remove the dents. You'll find it at Jo-Ann's or Hancock's next to the cutting blades. Sorry I can't be more specific.
There are self-healing mats, and others. If it does not say self-healing, my guess is that the cuts will remain. They were probably made using a heat process, but I have no idea of how to heat them up to repair them. They might give off noxious fumes if heated, so be careful, whatever you do.

Heating them makes the mats curl up , I once put a teacup on top of my mat, so I know.
I don't know but I do know the prices of everything has gone up when I was in JoAnn's & Hancock the other day. Mines has a few also but I don't use it much ;D *2U
This price thing I do not understand. So many people out of work and companies are laying off more all the time. Yet it seem gov. keeps raising taxes and companies keep raising prices. It is the raises in gro. prices that upset me the most, most other things we have a choice whether to purchase or not. H&*.
I thought they were self healing but I don't use mine that much. Sorry.
I thought so too, until I got some cuts on mines. However; they claim the newer ones today are better ;D *2U
I believe the green ones are self-healing. This one is the white quilters board. I have 3 boards now, would not like to try to purchase another. H&*.
Mine is not green but it is a self healing mat. Just check to see what the label says.
