how to clean the water tank?

there are two ways to clean the water tank, one is manual cleaning, and the other is cleaning with scale cleaner.

At present, many car owners basically use high-pressure water guns to clean them manually, but this method is not accurate. What we see on the surface is not the water tank, but the covered condenser, so if we use a water gun to wash it, we will not only fail to clean the water tank, but will make the dirt on the surface enter it with the washing of the high-pressure water gun. The accurate manual cleaning method is to remove the water tank of the car, and then remove the scale from the water tank by hammer, scraper or shovel. This scale removal method is complicated and inefficient, and it is very easy to affect the water tank and suffer secondary damage.

there are two kinds of scale cleaning agents, one is common scale cleaning agent, which also needs to disassemble the water tank, and the scale removal effect is not obvious, and it will cause certain corrosiveness to the water tank. The other is a professional scale cleaning agent, which is more efficient and simple. It does not need to disassemble the water tank, but only needs to introduce it into the automobile water circulation system, let it soak for 2-3 minutes, finally discharge it, and add water to rinse it repeatedly to effectively achieve the purpose of removing scale.
