At lingerie4two we recommend you wash you lingerie by hand. If using a washing machine for your lingerie place them in a mesh lingerie wash bag. This will protect all of your lingerie from being wrapped around the agitator. You should wash lingerie separate from your other clothing. When washing your bras, lingerie, panties or other delicates, it is suggested you use a delicate soda-based fabric wash. Regular detergents contain harsh chemicals that breakdown fabrics. Avoid putting your lingerie or panties in the dryer. The heat of the dryer breaks down the lycra, spandex and elastic, so you will find yourself replacing your lingerie, delicates more frequently. Rotate your bras. Bras do not need to be washed after every wear. This being said, you should avoid wearing a bra two days in a row. The bra will requires a day of rest after wearing, to return to its original fit and to breathe, wearing one bra constantly puts a lot of stress on the fabrics and causes it to rapidly stretch out of shape and to lose its fit. Replace your bras every six months. Most bras get worn out and do not function as they should after six months.
