Chapter 74 Shirts are best washed in cold water

Most people think that close-fitting shirts must be washed with hot water or warm water before they can be washed. In fact, the protein in sweat is a water-soluble substance, and the protein will be denatured after being heated. Between the fibers of the shirt, it is not only difficult to wash off, but also makes the fabric yellow and hard.

It is best to wash the sweat-stained shirt with cold water. In order to make the protein more soluble, you can also add a little salt to the water for better washing effect.

In addition to washing the sweat stains on the collar and cuffs with salt water, you can also use "washing collar" to wash, pour a little "washing collar" on the dirty collar, scrub or brush after a few minutes, and rinse with clean water after the dirt is removed.
