Non-acidic, fast-acting 20-minute radiator and cooling system cleaner

Use Radiator Flush and Clean as a complete cooling system flush to remove insulating built-up sludge and residue before changing the coolant in any cooling system. This procedure will ensure optimum heat transfer and efficiency of the entire cooling system. Whenever draining a cooling system, or changing brands of coolant, cleaning the system with Radiator Flush and Clean is always recommended.
Important: Never mix brands of radiator products and never under-treat with radiator products.
