On my wifes van there is a shelf between the front seats. 4 days ago the wife went shopping and bought a gallon of milk among other things. The gallon of milk slid under the shelf and nobory notice, and it leaked 2 qt. on the carpet and sat there for 4 days. I used the van yesterday and because of the smell found the half empty milk jug . Today me and a buddy pulled out the seats and tried to clean the carpet with a carpet steam cleaner. We mixed up a solution and added oxyclean. we extracted , scrubed and extracted again , sprayed Fabrese, and other deo. The smell is still there. Im letting it dry over nite , and maybe a miracle will happen. Do you guys have any idea on how to get rid of sour milk smell.
