Descaling
To wash the heat exchanger, which is completely dismantled from the gas water heater, you need to prepare a special cleaning agent. There are several options:

commercially available products intended for this purpose;
citric acid solution (100 grams of powder per 500 ml of water);
a solution of water with 9% vinegar in proportions of 1:5.
The heat exchanger is filled with a solution of vinegar or citric acid using a watering can and kept for several hours. The easiest way is to leave the unit to soak overnight. If scale removal is carried out with a special agent, then the proportions and holding time must be observed based on the instructions on the package. At the end, the contaminated solution is drained into the sewer, and the heat exchanger is washed with running water. For this, you can use a water hose from a shower with an unscrewed nozzle. The process is shown in more detail in the video:
