In my car, there is a cup holder on the left side of the steering wheel. While driving, my daughter knocked over her McDonalds large full soda which fell on the floor, driver's side under her feet. As soon as we got home, I pulled out my little green machine and sucked it all up. The attached sprayer worked wonders. It sprays while you are sucking up the liquid. Worked great, no sticky residue left either. So, I decided to use it on the back seat on a stain that my daughter made back in 2006. OMG, it almost took out the stain. You can barely see it where is was brown. I found myself wet vac the whole car. And to think that I bought this for the house with no auto in mind.
