An Iowa State DOT truck wash bay constructed for applying Salt-Away

The Salt-Away concentrate is diluted with water at 512:1 ratio in this 2500 gallon tank. The solution is pumped simultaneously to perforated overhead and undercarriage bars while the truck is slowly being driven into the bay and reversing out of the bay. This procedure gives the truck 2 applications of Salt-Away; front to back and top to bottom.
