Abstract
A spray clean stage of a pretreatment system for treating a product surface having contaminants includes a tank for holding a cleaning solution to clean the product surface. A solution applicator is in fluid communication with the tank through an applicator inlet. The solution applicator is oriented to spray the solution onto the product surface thereby removing the contaminants from the product surface. A partition at least partially covers the tank and receives runoff of the solution from the product surface being sprayed with the solution. The partition is oriented to direct the runoff of solution from the product surface into the tank at a location spaced from the applicator inlet to distance the contaminants removed from the product surface from the applicator inlet.
