Can r404 refrigeration system be cleaned with carbon tetrachloride?

Reason 1: Although carbon tetrachloride is volatile and has considerable solubility, it is toxic, harmful to human health and will cause damage to the atmospheric ozone layer.

Reason 2: Carbon tetrachloride can dissolve rubber, and cleaning system pipes with this substance will cause very troublesome consequences for some refrigeration systems using rubber gaskets.

The best way to clean the refrigeration system pipeline is to blow with high-pressure nitrogen first, and then blow with the same new refrigerant.
