Every late November, I have to deodorize my car. I drive anywhere from three to five high school football players home after practice or a game. Not to be rude... but my car smells like sweat, butt, and Axe (that awful stuff teen boys use to try to hide the smell). Anyways, any Febreeze product works well and you can use the one for cloth/carpets etc... If you want to go more “natural”, you can mix baking soda and water for a wipe down session. (I use this mixture on the leather seats with good results). If the spilled milk is on the carpeting, first make sure all the curds/wet stuff is pulled up with paper towels. You can then apply baking soda... let it sit for a few hours and vacuum it up. It wouldn’t hurt to leave the windows cracked a bit to let the air circulate. Hope this helps... milk does stink!
The vinegar wont’ stain will it?
