Summary. The main ingredient of soap is sodium fatty acids, which in ordinary water quality, will produce white precipitates of fatty acid calcium and fatty acid magnesium because the water contains hardness components such as calcium and magnesium ions, commonly known as "calcium soap" or "soap scale". Since they are not water-soluble, they will coagulate, precipitate, or float up to form flocculent white spots attached to clothing.

It can be soaked in an appropriate amount of white vinegar water and washed again.

If the stains are not removed after 2 hours, take out the clothes, add white clothes to the basin (add 1 bottle cap per half basin of water), stir well, put in the clothes and continue soaking, and the cumulative soaking time does not exceed 6 hours.

2) White clothes of colored or other materials: put the clothes into the basin, the stain part is attached to the bottom of the basin, measure 1 4 caps (10 grams) of colored clothes and 1 4 caps (10 grams) of the collar with the color stain net (600g specification) of colored clothes, pour them on the stains, cover the stains with other non-stained parts of the clothes, prevent air drying, let stand for 2 hours, and rinse clean.

Summary. Soap stain, the composition is fatty acid calcium, fatty acid magnesium. The main ingredient of soap is sodium fatty acids, and this surfactant is not resistant to hard water.

When encountering calcium and magnesium ions in hard water, insoluble calcium soap and magnesium soap white precipitate will be generated, which is soap scale. The precipitated soap dirt is rubbed and crushed, and it forms powdery white ash. Therefore, soap is not a good thing for washing clothes, especially clothes made of natural fiber fabrics, such as silk and wool, and they are most afraid of soap forming soap stains.

Because these two fibers have the property of absorbing soap scale. To wash high-end clothes, you can use laundry detergent, or special detergents for silk and wool. These are detergents that are resistant to hard water.
