Heavy-duty coolant cleaner • Effectively removes rust, scale deposits and oil contamination • Cleans the cooling system without leaving residues on the heat conduction surfaces • Does not damage metal surfaces, seals, hoses or plastics Contaminated cooling circuits prevent sufficient heat supply and can lead to engine damage. Once a cooling system is contaminated or blocked, it is impossible to resolve this by simply flushing it with tap water. Restore is a high-quality alkaline-based (acid-free) product that effectively combats silicates, plus oil contamination and solder joint corrosion.
