Removing scale and fouling from the plates of a heat exchanger

The plates should be put in water with qualified cleaning chemicals, and use a soft brush, or high-pressure cleaner with care.

There are two major rules to be strictly followed while chemically cleaning any heat exchanger:

1. Pay very close attention to the type of the chemical, it must be approved to be used with the material of your plates.
2. Never exceed the prescribed time of chemical circulation.

If the above rules neglected, plates may be damaged. Such cases are not so rare, unfortunately.
