It removes the dirt
The product gets four stars because I think it's overpriced. After receiving the product I would probably only pay $5 for it. It has a really Pleasant sent that last a decent amount of time. I'm not sure how well it cleans any bacteria or germs from the actual mat but it does remove most dirt and residue. Afterwards my mat was more slippery and harder to keep a firm grip while using. It felt like it did when it was brand new so that's a good thing.
Rating: 4 stars
