Bleaching is unnecessary on a regular basis when reusable pads are properly cared for. However, there are a very few situations where bleaching is helpful. (For example, after a vaginal yeast infection.) Done properly and infrequently, it will not wear down your fabric. While we cannot guarantee your fabric will not fade, it is unlikely when bleaching is done correctly. To do a bleach soak, use a disinfecting bleach which has 5.25% sodium hypochlorite. Add 1 Tablespoon bleach to 1 gallon of cold water. Soak for only 30 minutes and rinse with hot water, then wash and dry as usual.
