Water-soluble pen is a kind of marker pen that can keep its color under normal environment, fade in water and leave no trace. This pen is usually used as a temporary mark in cross stitch and embroidery. There are two kinds: one disappears when it meets water, and the other is immersion pen washing. You should use an immersion pen. To delete it, you can try the following methods:

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.
