During the winter months, vehicles are blasted by road salt, brine & ice melt causing metal parts and body panels to rust and corrode. Eastwood's Road Salt Neutralizer is a blend of inorganic acids, corrosion inhibitors and penetrants that neutralize the corrosive film left behind from salt & ice melters without harming painted or finished surfaces. To use simply mix 6 oz of Eastwood Road Salt Neutralizer with 1 gallon of warm water, spray or sponge on the solution and five minutes later hose off. One gallon of concentrate makes more than 21 gallons of Neutralizer. Ideal for any metal substrate exposed to road salt.
