Rislone has developed two solutions to keeping your car running cool!


We refused to make just another radiator flush. If we couldn’t develop one worthy of the Hy-per Cool name, we wouldn’t put it in our product lineup. After several significant refinements to our product formulation, what emerged from our lab was Hy-per Cool, the highest-performing radiator cleaner and flush you can buy. Hy-per Cool Radiator Cleaner & Super Flush by Rislone is a professional-grade, proven formula that effectively:

  •  Cleans the entire cooling system
  •  Removes deposits and coolant gel
  •  Reduces overall operating temperature and improves performance of cooling system
  •  Instantly neutralizes acids that cause corrosion
  •  Helps prevent formulation of scales & deposits
  •  Finishes the cleaning job in 30 minutes or less, no special expertise needed
