Ring around the collar is a common laundry problem that can be caused by a variety of factors, including hard water, deodorant, and sweat. It can be difficult to remove, but there are a few simple steps you can take to get rid of it.
The first step is to identify the cause of the ring around the collar. If you have hard water, you may need to use a water softener or add a vinegar rinse to your laundry. If you are using deodorant, you may want to switch to a clear or white deodorant. And if you are sweating a lot, you may want to wear an undershirt to help absorb the sweat.
