How to remove traces after the whiteboard pen and ink on the sheets are washed clean?

Whiteboard pen stains on paper can be removed by the following methods:

1. After the sheets are dried, pour alcohol (with a concentration above 80%) 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 sheets into the basin and stick the stains on the bottom of the basin. Measure the color of the collar of 1/4 bottle cap (10g) and1/4g bottle cap (10g) with the blue moon color bleaching bottle cap, pour it on the stain, let it stand for 2 hours, and rinse it off. If there are still stains after 2 hours, you can add appropriate amount of water to wet the whole dress and leave it overnight.
