The sheets in my hotel are white. But now there are indelible yellow marks. What to do?

Hello, the yellowing of sheets is a color stain problem, which is difficult to remove with conventional detergents. Different materials and colors have different treatment methods, which requires skill.

The specific methods for removing yellow stains from bed sheets are as follows:

1, conventional machine washing or hand washing with blue moon brightening laundry detergent.

If the yellowing of the paper is still not improved.

2, "color dye immersion method" immersion

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

* If necessary, the soaking time can be extended appropriately. If the color stains are not removed after 2 hours, take out the sheets, put the white clothes into the basin (add 1 bottle cap to each half basin), stir evenly, put the sheets into the basin and continue soaking, and the cumulative soaking time shall not exceed 6 hours.

(2) White sheets made of colored materials: pour a small amount of water (about 0.5 liter) into the basin, measure the colored clothing colored stain clean (600g specification) and the collar colored stain clean 1.5 bottle caps (60 g each) into the water, and stir evenly. Soak the sheets overnight and then rinse them clean.

* The amount of water should make the sheets just wet, and the net content of colored clothes and collars should be increased or decreased 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.
