Vortex High Pressure Detergent has been formulated for use in both manual and in-bay automatic car washing systems. The high volume foam and heavy concentration of VORTEX HIGH PRESSURE DETERGENT allows excellent foam stability at a very high rate of dilution. For normal cleaning, dilute Vortex High Pressure Detergent at the rate of 1 gallon of VORTEX HIGH PRESSURE DETERGENT per 500 gallons of water. For more difficult jobs and for higher foam volume, dilute 1 1/2 gallons of VORTEX HIGH PRESSURE DETERGENT per 500 gallons of water.
