What stinks should be inferior flannel. Just throw it away and replace it with a tasteless one.

The smell in the car for a long time will make drivers and passengers uncomfortable and affect driving safety.

Or if the odor is not very serious, it is recommended to take it directly to the sun for a few days, and the odor will dissipate. Just spray some medicine to get rid of the smell. If it is really impossible to remove the odor, it is recommended to replace it directly.
