Mcm backpack is black, and the shoulder strap will fade in hot weather, but it will not fade when wiped with wet wipes. What happened? Mcm backpack is black, and the shoulder strap will fade in hot weather, but it will not fade when wiped with wet wipes, because the moisture of wet wipes can help dilute the dye and it is not easy to fall off. When the weather is hot, the part of the shoulder strap in contact with the skin will be rubbed and worn due to sweating, resulting in the dye falling off. When wiping with wet wipes, moisture can reduce friction and wear, thus reducing dye shedding. Wet wipes are a kind of paper products used for cleaning and disinfection, which contain detergents and disinfectants. They are widely used in all kinds of cleaning work in daily life, such as cleaning skin, wiping tables, furniture, electrical appliances and so on.
