1. Wash the stain with clear water, so that the impact of water can wash the stain away as much as possible;
2. Knead the laundry detergent and rice into a paste, pre-coat it on the surface of the stain, and gently rub it repeatedly to rinse the washed stain;
3. Wash regularly with laundry detergent.
Note: It is difficult to completely remove ink stains in calligraphy. Repeating the above operations can reduce stains.
If it is pen ink, you can try the following methods:
1. Rinse the stain with clean water to dilute the stain as much as possible;
2. Apply the stock solution of laundry detergent to the stain, completely cover the stain, let it stand for 5 minutes (gently scrub), and add laundry detergent for routine washing;
3. If the above method can't remove the stain, pour a small amount of water (about 0.5 liter) into the basin, add 600g of colored clothes bottle caps of blue moonlight (an upgraded version of blue moon color bleaching) into the water, and stir evenly. Soak in clothes overnight, and then rinse.
The amount of water should make the clothes just wet, and the net content of colored clothes and collars should increase or decrease according to the amount of water. If there are still stains after soaking for one night, the soaking time can be continued to be extended.
