1. It is best to wash underwear by hand. Because the fabric of underwear is very soft, some decorations are delicate but also thin and fragile, and the underwire of the underwear can be easily damaged and deformed if not taken care of well, so you should gently scrub or scratch it with your hands. The parts are easier to get dirty. You can put the cups together and rub them together. The water temperature should not be too high, and it can be below 40 degrees. Do not wash with hot water, which will seriously damage the fibers.

2. Detergent specifically designed for underwear should be used. Because the material of underwear is relatively soft, try to use special underwear detergent for cleaning. If you don't have it, don't pour other detergents directly on your underwear. You can dissolve the washing powder in water first, and then put it in the underwear for washing. Do not use chemical detergents such as bleach.

3. Wash dark and light colors separately. Even if you wash by hand, you should wash dark and light colors, underwear and outerwear separately to prevent dark clothes from staining light-colored underwear, and outerwear has more dirt. Wash them separately to prevent underwear from being stained with more dirt.

4. Be sure to use a laundry net for machine washing. If it is necessary to machine wash, you must use a laundry net, and it should not be filled too full, preferably half, and do not put it together with hard clothes to avoid squeezing and deformation.

5. Do not twist it with your hands when drying. After washing, do not twist it with your hands. First squeeze out the water with your fingers, then wrap it with a dry towel, squeeze and absorb the water in the underwear, then smooth the underwear back to its original shape and clamp it with a clip. Hang the underwear upside down to dry where there is no elasticity. Try to place it in a ventilated place to dry naturally. Avoid exposure to the sun, which will cause the fabric to turn yellow and fade and make the fibers fragile. You can also fold the underwear in half and dry it to keep the cup of the underwear from deforming.

6. Collection and maintenance of underwear. The fibers of underwear are relatively weak, so don't pull hard when wearing them, and don't wear the same underwear for a long time. You should change it every few days to give the underwear enough time to rest. Be sure to make sure the underwear is completely dry when storing it. Collecting it when it is humid will not only make the underwear moldy but also easily breed bacteria. Don’t just throw it away. Casual placement will deform the underwear. It is best to button the underwear. Well, the shoulder straps are placed in the cup, and the whole thing is spread out flat. For bras without wire rings, one cup can be folded into another cup, and the underwear can be rolled into a round bar for storage, which is convenient and saves space.
