H.S.
Try mixing 30 drops of Grapefruit Seed Extract (GSE) with 8 ozs of distilled water. Spray that on and let it air dry. It works great at keeping away my daughter's diaper rashes. You can get the GSE at Fruitful Yield or other health food stores for a good price b/c it lasts FOREVER. Spray it on several times a day. You may want to take the GSE internally too to get rid of the overgrowth of yeast in you. Just make sure to mix it with distilled water as it is used up trying to clean the tap water.
