Your rash is probably a yeast infection. A friend of mine is head wound care nurse at a local hospital advised to place a tea bag, normal tea, in a glass bowl with 3-6 ounces of water, microwave for 30 seconds, allow the tea to sit for 6+ hours, then wash the area, fan dry and use Zeasorb powder.
Do this twice a day during breakout for 10 days. The tea just sets on my shelf, one dose lasts 3 days. The longer it sits the better to lower PH of the skin, retarding growth of yeast.
