The main cause of moldy hats is moisture. It is recommended that the clothes be cleaned in time, dried thoroughly and stored in a dry place. Mildew is difficult to remove, so different colors and materials require different cleaning methods.

1. If it is a hat made of white cotton, linen, or polyester, you can use Blue Moonlight White Clothes Stain Cleaner to remove mildew spots:

(1) Use laundry detergent first Wash the hat;

(2) Add 1 bottle cap (40g) of Blue Moonlight White Clothes Color Stain Cleaner (600g specification) to half a basin of water (about 2 liters), mix well, and add Soak white clothes for 30 minutes and rinse clean. If there are still stains that have not been removed after soaking for 2 hours, take out the hat, add another 1 bottle cap of this product to the basin, mix well, put the hat in and continue soaking. The total soaking time shall not exceed 6 hours.

Note: Do not use the original solution directly.

2. For colored and white hats made of other materials, you can use Blue Moonlight Color Clothing Stain Cleaner combined with collar cleaner to remove mildew spots:

(1) Wash with laundry detergent first Net hat;

(2) Pour a small amount of water (about 0.5 liters) into the basin, and use the blue moonlight colored clothing stain net (600g specification) bottle cap to measure the colored clothing stain net, collar Add 1.5 bottle caps each (60g each) into the water and mix well. Let the cap soak overnight and rinse clean.

* The amount of water should be enough to make the hat just wet. The amount of stains on colored clothes and collars should be increased or decreased accordingly according to the amount of water. If there are still stains that have not been removed after soaking overnight, you can continue to extend the soaking time (mildew is more difficult to remove and generally requires soaking for several days).

Note: The stain remover for colored clothing is not suitable for clothes that are prone to fading or dry cleaning. If you are not sure about the fabric of the clothing, you can try it in a hidden part of the clothing first; and avoid contact with metal on the clothing when using it. Keep buttons, zippers, metal accessories, etc. away from direct sunlight.
