You can buy Salt Flush from the retailers listed in "Purchasing Outlets" or order it online below.
Unscrew dispenser cup from the Salt Flush applicator and fill with Salt Flush concentrate. Replace the dispenser cup, taking care to ensure that the “O” ring is seated properly. Attach one end of the applicator to a garden hose and the other end to your hose trigger attachment. Commence spraying under your vehicle and start adjusting the knob on top of the applicator. Ensure thorough flushing throughout undercarriage and wheels. Use Salt Flush each time the vehicle comes in contact with salt or minerals to help prevent rusting and corrosion.
