A few of my husbands shirts seem to be ruined by stains under the arms. On the light colored shirts, I can’t remove the yellow rings, and on the dark colored shirts, the area under the arms seems almost to be bleached. (Which I assume is caused by his deodorant.)
Are these shirts a lost cause? I’ve tried stain removers, and bleaching the whites, but the stains remain.
In the future, how can I prevent this? Is there some kind of treatment I could use in every wash?
