This product is a rinseless car wash. Basically, two gallons of water should be enough to clean the entire car without a hose. Great for people living in areas with water restrictions, apartment complexes where there is no access to a hose, or in a warm garage during the cold winter months. I was skeptical at first, but after hearing rave reviews from members of autopia.org. I thought I would give it a try. Although I did not prerinse the car, I highly recommend it. Although I think I have proven that it is not 100% needed from the photos attached.
Basically you use two MF towels. One to wash the car, and the other to dry off. The dry towel should NEVER become dirty if done properly. The wash towel should be soaked/agitated thoroughly into the bucket to make sure the dirt and particals go into the water.
Before Photos. Notice all the dirt and salt from my friends at WVDOT.
Two cap fulls is all you need
and 2 gallons of water
