Be sure to choose the right one, such as tide. I think good washing powder is the key.
As for how long to soak, the so-called scientific soaking time is 8 to 15 minutes, and I have no personal experience. The clothes were soaked for a day or two and didn't feel difficult to wash. It is the same.
But if you follow the fast standard you emphasized, it will take about 10 minutes. When washing like this, you don't need to rub hard. As long as you don't kill pigs and are not greasy, you don't have to wash them. If you are a working class or a student, it will be very labor-saving to wear clothes. I basically wipe it and it will be clean. I just need to take care of the neckline, knee cuffs and some places that are easy to rust. It's still easy to wash.
So even in winter, I never use the washing machine. I don't think washing clothes is that difficult.
If there are a lot of clothes to be washed, it is best to sort them when soaking. The first thing to pay attention to is to avoid soaking faded clothes with other clothes, especially white or other light-colored clothes that are easy to dye.
The second is that the coat and underwear should be soaked separately. If you want to save water, you can also wash your coat first and then wash your underwear with the rest.
Faded clothes must be washed separately. Don't wash other clothes with the rest of the water. If there is enough water, clothes can be classified and soaked separately.
Pay attention to washing with water after washing, and don't leave white foam of washing powder. In that case, light-colored clothes will show traces when they dry.
I have washed a lot of clothes together, a dozen large and small, but the whole washing process will not exceed 40 minutes.
If it is too much, you can wash it in batches if you are not in a hurry. Don't tire yourself.
