I have two types of stains in my car.. the color of my interior is taupe, which is fairly light. I spilled a double gulp (the 64 oz 7-eleven one) full of coca-cola and my ex gf spilled a giant jug of cranberry juice in the back seat on the floor as well. My question: can I ever get the carpets to look as clean as they did when i first got it? Any relatively inexpensive remedies? thx in advance!
