Drum washing machine cleaning Many people know that the washing machine has two barrels, an inner barrel and an outer barrel. There is an interlayer of about two centimeters between the two barrels, which is also the place where dirt is easy to deposit. But it is impossible for us to clean the washing machine and dismantle it, and the easiest and most efficient way is to use special washing machine cleaning agent or descaling agent, which will only produce a small amount of foam, which can strongly remove the internal stains, bacteria, and odors of the washing machine without damaging the machine. . Be careful not to use ordinary washing powder or liquid detergent instead of washing, which not only has no effect, but may also cause foam to overflow and damage the machine.
