FOAM GUN: Add approximately 4 ounces of REFRESH wash soap to the foam gun. Fill the foam gun with water to the manufacturer’s recommended instruction. Pre-rinse any heavy dirt and debris from the vehicle before applying the product. Spray REFRESH from top to bottom, working your way around the vehicle. Allow REFRESH to dwell on the surface for up to 30 seconds. DO NOT allow the product to dry on the vehicle. Rinse the vehicle from top to bottom, working your way around it. Dry the vehicle with microfiber towels or use an air blower for optimum results. Depending on the size of the vehicle, washing in sections may be ideal.
