Milk stains are water-soluble stains. The newly stained milk stains can be soaked in cold water (1 degree) for 3-60 minutes, and then washed repeatedly with raw soap to remove them. When soaking, a little salt or ammonia water can improve the decontamination effect. Old milk stains are difficult to remove, and the following methods can be considered:

(1) After grinding radish or white radish, mix it with salt, smear it on the stain, rub it repeatedly by hand, and then rinse it with water. Because protein in milk meets amylase in radish, it will decompose, thus removing stains. ?

(2) It is also effective to scrub milk stains with ginger. ?

(3) Wash with detergent first, then with dilute ammonia water, and finally with water. Milk stains should not be washed with hot water. If it is too high, the protein in this kind of stain will be firmly combined with the fiber, which is more difficult to remove.

Extended data:

The shorter the stain stays on the clothes, the easier it is to remove. Sometimes different materials of clothes will also affect the removal effect of stains. Stains can easily penetrate into fibers to form stubborn stains, and it is difficult to remove stains if they are not handled properly. It's easy to wash as long as it doesn't stay overnight.
