I too had the same issues with the rash, infection, etc. in the folds of my "fat". My aunt used to work in a hospital and told me to go out and buy a bottle of BAN Roll On deodorant (unscented or regular) which currently comes in a lime green bottle and roll that on the infected area (under the fat on my stomach and under my breasts) and wow w/in few days, infection is gone, no more rash. I have been using BAN every day since after I get out of the shower in the morning and I am so happy now.... try it.
