I bought a hard plastic desk mat today, which has a pungent smell. Can it get rid of the smell in the sun?

If it is a transparent table mat that you just bought and has a pungent smell, you can clean it with laundry detergent, put it on the balcony, and disperse the smell through ventilation and drying. After a long time, the smell basically disappears.

If the transparent table mat gives off a pungent smell, it is mainly the smell of plasticizer. If the odor is serious and heavy for a long time, then use inferior plasticizer, which volatilizes slowly and it is difficult to remove the odor by cleaning. Suggest throwing it away. After all, it is harmful to the human body. When buying transparent table mats, try to choose products with big brands and good quality, so that the taste will be relatively small.
