There is a mark on the white dress. How can I wash it off

1. After the clothes are dry, pour alcohol (above 80% concentration) into the stain and dissolve it for 5 minutes;

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 methods can't remove the stains, put the clothes into the basin, and the stains will adhere to the bottom of the basin. Measure out 1/4 bottle cap (10g) with the blue moon colored floating bottle cap, pour it on the stained part, cover the stain with other stain-free parts of the clothes to prevent air drying, and let it stand for 2 hours before rinsing. If there are still stains after 2 hours, you can add appropriate amount of water to wet the whole dress and leave it overnight.

4. Wash the oil painting with turpentine, because it tastes great, you can also wash it with tasteless turpentine.
