Prestone® Super Radiator Cleaner is designed to remove heavy rust and scale deposits in neglected cooling systems.
These deposits can dramatically restrict coolant flow and reduce heat transfer, which may lead to possible overheating, breakdown or costly repair. A super chelating additive effectively removes heavy deposits by drawing metal oxides into solution. Though strong enough to help restore maximum cooling system efficiency, this non-acidic product is easy to use and safe for all cooling system metals. For more information, visit prestone.com.
