I have 3 Olfa mats in various sizes and have not had any problems with any of them. They all get used and the rotary cutter hasn't left any marks on them. I do keep them clean and pretty lint free. Wiping them down with a damp cloth at the end o the day seems to do the trick for me.

I have an Olfa...but it is a mess. I cut a lot of fleece on it, and think I need to wash and scrub it! My sister also left an iron shinny spot on it...not the mats fault. I use the back side for all the fleece!

Martelli mats and rotary cutters are by far the best thing out there. One quilter/sewer's opinion. Have used both for years and want buy anything else.

I HEARD olfa HAS A LIFETIME WARRANTY, SO GIVE THEM A CALL, THEY WILL SEND YOU A NEW ONE, THEY WILL WANT A PICTURE OF YOUR MAT.

I bought the big mat (I think 30x60 or maybe bigger?) from Martelli when they had it for 1/2 price. It is the type that repairs itself. I really like it. I also have a 36x50 (I think) mat that is out of that really hard plastic or whatever it is called that evidently came from a quilting store. I really like that one too. If you sign up to receive Martelli newsletters, they will let you know when they have their 50% off sales.

I have a Martelli mat and one thing I have found is don't cut batting on it. My mat is now fuzzy. So I too need to find a way to clean it up.

I have a June Taylor that I use a lot. No problems. Also have an olfa but not used as much. Both of these mats are old. Maybe they changed the way they are made now.

I learn so much from this board.....I had no idea cutting boards need to be soaked. I have olfa in 6 different sizes, including the large rotating one. The first two I purchased in 2008, I have never had any problems with them. Should I soak them?

Olfa can be soaked, not sure of the others. always check first.

I have only one large one for 12 years and use it all time! I think a lot of things are not as good as they used to be!
