Help, a few days ago some milk was spilt on my car seat. Within 10 minutes I had cleaned it with some hot soapy water and breadsoda. But yesterday the smell started. It is dreadful. Its like some animal has died and been left to rot in my car. I have tried leaving some breadsoda in an open container in my car, but the smell is still there. I had to drive 200 kms in my car last night and had to stop and buy some airfreshner- the smell was that bad. I should say that the seats are not covered in cloth but are covered in mock leather. Any helpful tips would be gratefully received.
