To hand wash bras, let them soak in an alcohol-free detergent and hang to dry. Bras should be washed about every two to three wears, and replaced every 6 to 9 months.
Hand washing delicate lingerie, including bras, is recommended over machine washing. This ensures the garments keep their shape as long as possible.
Step 1: Prepare the washing solution
Fill the sink with lukewarm water. Add a gentle, alcohol-free detergent. Detergents specially made for baby clothes work well.
Step 2: Wash the garment
Immerse the bra into the detergent solution. Gently rub the fabric together to work the detergent in. Let the bra soak for an hour or so. Rinse well under cool, running water until the water is clear.
Step 3: Dry the garment
Never wring or twist the bra to remove the excess water. Instead, lay it flat on a towel and place another towel on top. Press gently to remove the water. After the excess water has been removed, hang the bra to dry completely. It should never be dried in a dryer, since the heat will break down the elastic and the bra will lose its shape.
It is possible to wash bras in a washing machine. Hook the bra's back and place in a lingerie bag. Set the machine on the gentle cycle and use a gentle, alcohol-free detergent. Hang to dry.
