I can vouch first hand that these work! A sippy cup of milk got left under my husbands car seat, it went sour, exploded, and left a terrible smell. One of these bags worked wonders. We’ve also used them in our basement to neutralize the “basement” smell. You charge them in the sun and can reuse them over and over. Amazon is running a Deal of the Day on a 5 pack ($20.99– reg. $45.99)!
