Be sure to get all stained edges and areas, inside and out. Rub the bleach into the fabric, or use a toothbrush to scrub the area. Wash your hands when you are done. Color-safe bleach can be used on any bra: white, solid colored, or patterned. The active ingredient is hydrogen peroxide, which does not leach dye from fabric like chlorine bleach. This will give the bleach time to break down the stain and remove it from the fabric. You can leave the bleach on for up to an hour if the stains are severe. The detergent will help remove the bleach as well as the stains. Do not wring out the bra, but gently press the water out of it. Try gently rolling the bra in a clean towel to remove the excess water. The sun is an excellent bleaching agent, so this will help remove any lingering stains. Using a dryer to dry your bras can damage the fabric, including the elastic and underwire,  and leave your bras misshapen.
