Suzuki swift warm air small water tank is blocked. Does coke work?

it doesn't work. Coke is a kind of drink, which contains corrosive substances such as sodium cyclamate. Suzuki Swift's small warm air tank is blocked and cannot be cleaned with coke. If it is used to remove the scale and rust in the water tank, it will cause metal corrosion in the water tank, which is not conducive to the use of the water tank, and it is also easy to stick the impurities in the water tank together, resulting in poor water flow in the water tank.
