Can a washing machine without washing powder clean clothes?

Not only washing clothes can be like this, but bathing and washing vegetables can also be done. This invention has been invented for many years. Some people say, old Youdan, why don't you try washing it? I think I can dress up as an old oil Dan, not only can't use the washing machine, I think they may not even have seen washing powder! If you can't wash clothes several times a year, just rub them with plant ash, hit them with a wooden stick and wash them in the river. I remember hearing a joke many years ago. A lazy woman asked a neighbor who combs her hair every morning, sister-in-law! Doesn't it hurt to comb your hair every morning? I comb my hair once a year and it still hurts like hell! For many years, human society has been pursuing more and more civilized spiritual life, among which the biggest gap with foreign countries is sanitary habits. It's messy because it's dirty, and poor because it's messy. Cleaners in China use brooms to lift underground dust to the sky, which makes the pollution worse than not cleaning, so they import a number of road cleaning vehicles. Because there was too much dirt, they were blocked on the road, so people decided that this thing was useless at all! ! ! In this way, the world's most sophisticated cleaning car was put into the cold palace.
