One of the most general and effective uses of Vaseline is in helping to prevent chaffing-related rashes or irritation caused by clothes. Runners and cyclists will often apply a small amount of Vaseline to the insides of the thighs to avoid chafing during a long race. Some people move violently with nipple chaffing caused by certain articles of clothing or varieties of fabric. If you have a problem with chaffing, apply a defensive coat of Vaseline to the area to keep yourself moving.
