1. Silk underwear needs to be changed and washed daily to keep it clean. Dirt is not only dirty on the surface, but also affects the ventilation, water absorption and heat preservation of the underwear, and sweat can damage the material and destroy its proper function. Therefore, every time you wash the clothes, try not to put them in the washing machine (if you put them in the washing machine, be sure to use a laundry mesh bag), it is best to gently rub and wash with your hands patiently.
2. When the water temperature is below 40°C, add a mild and easy-to-dissolve washing solution into the water. After the water is soaked, the lingerie to be washed is immersed in the water for 5-10 minutes. The amount of detergent should be appropriate, if it is too much, it will not be easy to wash off. First wash off the stains with clean water, and then use detergent to dissolve in water to wash a second time. Moreover, do not wash with used sewage in order to save water, so that the dirt attached to the underwear will make it even more dirty.
3. The detergent should be rinsed off. The detergent left on the lingerie is likely to cause discoloration, and the soaking time should not be too long, otherwise the chloride in the tap water will damage the inner material. Rinse thoroughly at the end. Once the detergent is not rinsed, the clothes will deteriorate easily.
