The odor is caused by the self-healing materials and sometimes the odor can be very strong. There are some tricks to get the odor out:
- Wash the mat with a mild soap and let it air out. This may take a few weeks
- Spray Febreeze on the mat and let it air out.
Store the mat in a sealed container with some coffee beans or some crumpled up newspaper. Those two items help absorb any odor.
