I unknowingly left a gallon of milk in the back seat of my car and unfortunately some of it spilled last night. Woke up this morning and saw some of the runoff in my driveway. Does anyone know what's the best way to clean this? It went straight thru the seat wedge, down into the carpet(directly underneath the rear bench) and came out thru some hole underneath the car. Do I need to remove the rear seats to get to that carpeting?
