You may recall my post Is your Self Healing Cutting Mat Smelly?" from about a week ago. At that time I had just bought an 35" X 70" (3-24"X36" mats that clip together) Olfa cutting mat which was giving off a strong chemical odor. After reading reviews about this and seeing it mentioned on the Olfa website I was concerned about whether or not I would be able to get rid of the strong odor. Well I decided to forgo the vinegar/water bath tub soak suggestion that was recommended by others and the Olfa website and instead directly called Olfa to inquire about a remedy to the problem. Well I talked to a nice lady who gave me a couple of suggestions to try. Now at first I must admit that I wasn't sure if any of these treatments would work. But after 2 separate times of soaking my mats in a bathtub of cool water and lemon dishwashing liquid overnight, rinsing them and allowing them to air dry (both outside in the evening air and in the garage) for a couple of days--- I'm proud to announce that the horribly strong smell has dissipated and I'm LOVIN' MY NEW CUTTING MATS! I've always loved using my rotary cutter and am happy I have a large enough cutting mat surface to do so!!!! Cutting fabric is my least favorite part of sewing so using my rotary cutter helps to speed things along. So I have to strongly recommend the Olfa 35"X 70"cutting mat, especially if you're looking for a large cutting mat for your sewing table. If your mat has a strong chemical smell, try soaking it and air drying it as suggested to see if you can remedy the issue:)
