The CPS Products 590260 Auto-Remarketing Cleaning Solution is designed exclusively for use with the MiST Ultrasonic Cleaning Machine (sold separately). The cleaning solution treats mold on contact and prevents new mold growth throughout a vehicle's HVAC system and passenger cabin surfaces. It is ideal for use with pre-owned vehicles, helping to restore the interior environment. The MiST system is aimed at improving the health of the driver and occupants, not the vehicle.
