How can I wash the blue and black pen water off the sheets?

Hello! There are steel ink stains on the paper, which can be cleaned by the following methods:

1. Rinse the stain with clean water to dilute the stain as much as possible;

2. Apply the stock solution of special laundry detergent for Blue Moon hand washing to the stain, completely cover the stain, let it stand for 5 minutes (gently scrub), and add Blue Moon laundry detergent for routine washing;

3. If the above method can't remove the stain, then

(1) Pure white clothes made of pure cotton, linen and polyester: every half basin of water (about 2 liters), add 1 bottle cap (40g) blue moonlight white clothes stain (600g specification), stir well, soak in the clothes for 30 minutes, and rinse off.

* If necessary, the soaking time can be extended appropriately. If the color stain is not removed after 2 hours, take out the clothes, put the white clothes into the basin (add 1 bottle cap to each half basin of water), stir them evenly, and continue to soak them in the clothes for a cumulative soaking time of no more than 6 hours.

(2) White clothes made of colored or other materials: put the clothes into the basin and stick the stained parts on the bottom of the basin. Dip the bottle cap (600g specification) with blue moonlight color clothes, and measure the blue moon collar of1/4g bottle cap (10g) and1/4g bottle cap (10g) stained with colored clothes. If the stain is still not removed after 2 hours, the standing time can be extended to overnight.
