When chocolate gets on clothes, don't wash it with hot water until the chocolate stain is completely removed. First, remove chocolate solids from clothes to avoid expanding the contaminated area, and then rinse the contaminated area under the faucet. When the stain becomes lighter, apply a proper amount of laundry detergent to the stain. After five minutes, rub the stained area by hand until the stain is removed.
If there are deep chocolate traces on light-colored wool and silk fabrics, cotton balls should be soaked in warm (35 degrees Celsius) glycerin and wiped until they are removed. You can also soak in gasoline to remove all the grease on site, and then wipe it with ammonia solution with the concentration of 1%, and the ratio of ammonia to water should be 1: 5. When the chocolate stains on silk fabrics are difficult to remove, ammonia water (1%) 1, glycerol 2 and water 2 can be used to make glycerol ammonia solution, which can be dipped with cotton balls.
