Cutting mat problem and looking for answer....
Hello there fellow quilters -
I'm looking for a possible cause of a problem with a cutting mat - my friend washed hers per manufacturer's directions and laid it flat to dry.
Now, every time she cuts on it, the blade of her rotary cutter rusts (overnight). The mat is completely dry, and at six months since washing it, the blade still rusts. She does not have this problem with the same brand of blade on a (non washed) mat of the same brand.
The manufacturer of the mat has not been helpful at all, blaming the blade as defective (in spite of the rust only happening on this washed mat)
I was querying a possible residue of soap on the surface of the mat.... she doesn't think that's the case. In fact, she can cut on the other side of the mat without any rust occurring..
So, seeking your thoughts on cause of the rust and possible solutions as the problem side is the one with the markings on it, of course.....
