Before using your shoes in the morning - (do not apply the product to sweaty shoes) sprinkle one package into a pair of shoes. Make sure it disperses. You can use your shoes while the product is inside your shoes. Sprinkle a small amount of the product in different parts of the closet in the shoe cabinets - apply it to the inside of the shoes where the smell is intense. The effect will begin as soon as it is used on the shoes. You do not need to wash your sneakers and slippers. Get rid of the smell without having to wash your shoes. Wearing socks under normal conditions does not cause a decrease in the effect of the product. It is recommended that you apply the product before putting the shoes that will not be used for a long time on the shelf to remove the odor in the shoes and extend the life of the shoes.
