It's inevitable. My wife takes the car out and comes home with a soda spilled in it, ketchup on the carpet, or worse -- a juicy juice box leaks on the upholstry. Not only are stains like this difficult to combat, it's difficult to find a cleaner that wont change the color of the surface after the stain is removed. Perfecar's Stain Zapper is strong enough to allow a simple spray on and wipe off -- there is no hard scrubbing to get the job done. You can use it as a spot remover or even on the entire carpet as a cleaner.
