Does sweat turn white clothes yellow around the area where sweating?
the reason it looks like sweat turns your clothes yellow is because that is where you had applied aluminum to your skin and it reacted with the fabric and turned it yellow instead of trying to fix the clothes after they turn yellow, try using a non aluminum deorderant [rock/bar/stick] and solve the problem before it happens these rocks last what seems like forever, does not harm your fabrics, makes it little black dress wearable, and is better for your pocketbook because of how much money you will save
