Regular maintenance is required to maintain the cooling performance of a water cooling system. For this reason, Alphacool has developed the Core Loop Cleaning Liquid. Thanks to its composition, the concentrate has an antibacterial effect and can effectively remove residues. In addition, it protects copper, chrome, brass and nickel. The Core Cleaning Liquid should definitely be used for the next cleaning. Simple and effective! The concentrate should only be mixed with distilled water or Alphacool Ultra Pure Water without additives, not with tap water! Depending on the degree of soiling, the mixture runs through the water cycle until the desired result is achieved. Thereafter, the mixture is drained and the components are rinsed once more with distilled water. This removes all residues and protects the components over the long term. The circuit can then be refilled with any liquid. Mixing ratio: One bottle of Core Loop Cleaning (100ml) to 1 liter of distilled water. Note: The cleaning agent loosens dirt and deposits from the surface. However, they are not resolved. It can therefore happen that the loosened dirt gets stuck in the cooling fins and possibly causes blockages. It is recommended to thoroughly flush the radiators with distilled water. For a complete cleaning, it is also recommended to disassemble the cooler and clean the cooling fins separately with a soft toothbrush, for example.
