Washing machine not cleaned after long use - dirtier than a toilet? Let me teach you a trick - no money needed, clean and bacteria-free

The washing machine is a household item we use all the time, but a washing machine that gets used every day will become very dirty if it is not specially cleaned. After all, the clothes we put in every day are not exactly clean - sweat aside, some have picked up quite a lot of dirt outside. During the wash cycle, this dirt disappears from the clothes, but some of it still remains inside the washing machine, and over time the washing machine becomes very dirty. Some people even feel that such a washing machine is not much cleaner than a toilet. So cleaning the washing machine is a very necessary thing to do, but how can you clean it thoroughly, quickly and easily? Let me tell you a method - just follow along and you will be fine, and it does not even cost any money!
The materials we need are also very few - one towel and one bottle of vinegar are enough. These things are basically in everyone's home, so there is no need to buy anything extra, and no need to spend money.
First we pour the vinegar into a basin, then throw the towel in to soak. This process is crucial - you must let the towel soak fully in the vinegar, only then can the washing machine be cleaned properly afterwards. Then we throw the vinegar-soaked towel into the washing machine.
After putting it in, we press the spin-dry cycle, and then this vinegar-soaked towel will roll around over and over inside the washing machine. When you open the washing machine again, you will find the towel has become very dirty, but the inside of the washing machine is already much cleaner! At this point add some water, rinse the washing machine clean, and it is done.
