Dh's t-shirts all end up with really crusty armpits. He's replacing them with new ones and I want to know how to prevent it from happening. I've read bio detergent is good but he has sensitive skin and usually itches if we try a different detergent to the normal non bio one we use. Does a sensitive bio detergent exist?
Or does anyone have any other tips on preventing them from crusting up? He's reduced the amount of deodorant but that's not stopped it. Thanks!
