CRC Salt Terminator Engine Flush 1 Gallon, Dissolves Salt and Provides Non-Greasy Corrosion Protection

CRC Salt Terminator is a 1-gallon engine flush and corrosion inhibitor that dissolves salt deposits and leaves a protective film to help prevent rust and corrosion in marine and automotive systems.

Salt buildup and residual corrosive particles shorten the life of cooling systems, engine internals, and exposed metal on boats, RVs, and powersports equipment. CRC Salt Terminator is formulated to dissolve and remove salt and salt-related debris while depositing a non-greasy protective coating that inhibits future corrosion. It is suitable for both saltwater and freshwater environments and designed for routine maintenance to reduce the risk of costly, corrosion-related repairs.

How does CRC Salt Terminator remove salt from engines and cooling systems?

The formula chemically breaks down and dislodges salt crystals and trapped deposits inside heat exchangers, hoses, and engine passages so they can be flushed away. It works as a heavy-duty cleaner during a maintenance flush and is compatible with common engine cooling systems when used according to directions.

• Dissolves salt, mineral scale, and deposits to restore flow.
• Flushes cleanly from passages when followed by a water or coolant drain.
• Safe for use in both freshwater and saltwater-exposed systems when instructions are followed.

Will this product protect internal parts after cleaning?

After dissolving contaminants, CRC Salt Terminator leaves a thin protective coating on internal metal surfaces to help slow future oxidation. The coating is non-greasy and designed to provide short- to medium-term corrosion inhibition between maintenance intervals, not as a permanent seal.

• Deposits a corrosion-inhibiting film on exposed metal surfaces.
• Reduces immediate re-exposure damage from residual salt and moisture.
• Best used as part of regular maintenance cycles for ongoing protection.

Which vehicles and gear can I use Salt Terminator on?

CRC formulated this product for a broad range of marine and land applications where salt exposure is a concern. It is intended for cooling systems and internal engine passages, plus exterior metal parts and equipment that suffer salt contamination.

• Boats, PWCs, and outboard and stern drive cooling systems.
• RVs, trucks, ATVs, motorcycles, and industrial or heavy-duty engines.
• Trailers, fishing gear, patio furniture, and other salt-exposed metal items.

How should Salt Terminator be applied for best results?

Follow the manufacturer’s instructions specific to your engine type and cooling system for dilution, contact time, and flushing procedure. Typically it is introduced during a flush cycle, allowed to circulate or soak to dissolve deposits, then flushed out and followed by a rinse and coolant refill as required.

• Use the recommended dose and contact time for engine or part size.
• Circulate or soak to ensure deposits are loosened before flushing.
• Rinse thoroughly and refill with appropriate coolant or water after treatment.

Who is this for: CRC Salt Terminator is for boat owners, marine technicians, RV and powersports enthusiasts, fleet managers, and anyone who maintains equipment exposed to saltwater or de-icing salts. If you service engines, cooling systems, or metal equipment and want to remove salt deposits while leaving a protective film to reduce corrosion between services, this 1-gallon professional-grade formula is designed for routine maintenance and periodic heavy-duty flushing.

Note: Always consult your engine or equipment manufacturer’s recommendations before using chemical cleaners in cooling systems or on sensitive components.
