I had a bad bout with rash last year. Found out that my wife had added Oxi-clean to the washer with my clothes to get the stains out. There is a resedue left in the clean clothes from the Oxi-clean that I must be aleargic to. Where ever sweaty clothes were on my body, my body looked like hamburg and it hurt soooo bad. Rewashed all my clothes with our normal laundry soap and haven't had a problem sence.
