On my dress and polo shirts I noticed I developed stains from my deodorant in the armpits. Do you know of any deodorants or tips to avoid this?
I know the issue and I think there are no great solutions to the problem. I’ve tried those deodorants that are supposed to leave no stains, they haven’t worked for me at least. If you wear something under your polo/dress shirts that might help, it will absorb most fluids.
Also I found this at Permanent Style by Simon Crompton:
Put some extra detergent on the armpits, collar and double cuffs of a white shirt before you wash it. At least do the armpits on every other colour. Sweat stains are a poor excuse to rid of a shirt.
Might be worth a shot? Hope this helps, cheers!
