I got the white mat, and that may be where the issue lies. It got VERY dirty VERY fast, but it was like a greenish brown stain, not normal dirt color. It’s definitely small, but I knew that because I needed it for a small space. The threading fell apart quickly. It’s labeled as washable, but when I washed it, I think it made the stains worse. But it warped and the fabric hardened in place. Makes me wonder what the mat is coated in or made with.
