How is it better to wash a sweater?

1. When cleaning, first check the trademark and how to clean it. Hand washing is the best way to clean all sweaters, followed by a washing machine and not through dry cleaning.
2. Pay attention to the water temperature control during cleaning, preferably around 30 degrees.
3. Try to use neutral detergent as much as possible. If the alkalinity is too strong, it will not only be difficult to clean the ingredients on top, leaving white marks, but also have a corrosive effect on the clothing, making it dry and hard, and losing the comfort of the sweater.
4. When cleaning, you can add some vinegar to the water, which makes it very easy to remove the chemical costs on it.
