I didn't realize when purchasing this mat that the "graphite" was so heavily coated. It's like having glitter everywhere. The mat was purchased for the entry door from the garage to the laundry room which is where we enter and exit our home and take the dog out. I have graphite in the laundry room that I am constantly sweeping up. I liked the definition of "clean scrape", however it's not a clean scrape. If I hadn't have thrown the box away, I would return this product.
