After you wash your car, it’s looks clean. However, even though all the dirt has been cleaned off the paint, there will almost always be dirt and contaminants in or bonded to the paint. This bonded dirt will reduce the gloss and shine of your car’s paint work.
The picture shows a car that was completely washed and dried. After we dried it, we sprayed a “fall-out” or “decontamination” product and it shows the reaction with the bonded dirt. After rinsing, we repeat the process until no further “bleeding” or reaction can be seen.
