How to solve the oil drops on the sheets?

1. First, use warm water (the water temperature should not be too high) to dissolve and remove the colloid in the stain.

2. Decolorize with detergent (neutral or acidic). Note that ordinary household washing powder is alkaline. Don't use the washing machine when washing. Gently rub it with your hands, don't brush it, and finally rinse it with water and dehydrate it with a dehydrator.

3. After acid treatment (edible white vinegar can be used): pour the amount of water soaked in the bed sheet into vinegar (1 kg, about 1/4) and stir it evenly, then soak it in the dehydrated bed sheet for 5 minutes to increase the bright luster of the silk fabric, and then bleach it with clear water.

Note: move quickly and minimize the soaking time.
