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

2. Apply the blue moon hand washing or deep cleaning laundry detergent stock solution to the stain, completely cover the stain, let it stand for 5 minutes (gently scrub), and add the blue moon laundry detergent for routine washing;

If the above method can't remove the stain of the pen, pour a small amount of water (about 0.5 liter) into the basin, measure the stain-free caps of colored clothes and collar (each 1.5g) with blue moonlight colored clothes (600G specification), add them into the water, and stir them 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.

Caution: The blue moonlight stain on clothes is not suitable for faded clothes and dry cleaning clothes. Avoid touching metal buttons, zippers and metal ornaments on clothes.
