Once completed, allow the enzyme spray to settle in for 24-48 hours while the active enzymes go to work in literally eating through the odorous residues. After 1-2 days have passed, the enzyme moisture can be blot dried, leaving a freshened car interior behind. As a note of precaution, avoid using this enzyme formula on leather or suede automotive upholstery.

After sprinkling the carpeting over the smelly areas within the carpeting, provide 3-4 days for the baking soda to have it’s full effect before vacuuming or sweeping it out of the automobile.


5 Coffee Ground Trays

As another absorbent measure, coffee ground trays can work to pulling difficult automobile odors. Spread a cup of coffee grounds across two different cookie trays. Next, place the trays under the two front seats and allow them to remain the for 1-2 weeks. During this time, the grounds will work to absorb the residual milk odors and replace them with the subtle aroma of coffee beans.

If any smell remains after the an entire day within the sun, try placing your car out for a second or third day until it has become entirely freshened.
