Haha! The operation steps are actually very simple. You must first prepare a washing machine tank cleaner. I personally recommend that you try Jiaan’s second generation washing machine tank cleaner. It is quite good. It has a patented technology called Li Polyester Core, which can kill Kills 99.9% of bacteria in the washing machine. Then take out one of the small bags. There are three bags in a box of Jiaan. Pour it into the washing machine, add water to the high water level, run the washing machine to allow the detergent to fully dissolve, and then you can play. After an hour, wash clothes as usual. The program, washing, rinsing, and dehydration are all run once, and the washing machine tank will be clean.
