I don't know about removing under arm stains, they always have come out in the wash for me. As far as the cuffs go I would wet them with liquid laundry soap or resolve and scrub with your hands. That is what I used to do with my husbands shirt collars. I think the key to these kinds of problems is not to let them get that bad. My husband did hard manual labor out side with junk yard cars and put on clean clothes every day. I washed them as soon as he took them off. No problem.

The French cuffs would be treated like regular cuffs. I always used to use a pre-treat like Shout. Now that I discovered 'free and clear' type detergents with enzymes as well as 'free & clear' type oxygen bleach (Ecover), I don't use the Shout as often, unless I see cuffs that are really nasty.

If nothing else works, I would try soaking the cuffs only in a bucket of hot water with the detergent. If you use a liquid detergent that has enzymes, perhaps use that as a pre-treat for 5 to 15 minutes before washing. I've done this with Persil Color Gel on my dark garments, with great success.

I hit "post" before I meant to.

If you go to the bottom of this page, in the "Search" box enter the word deodorant. You'll get a lot of previous discussions that have solutions.

Pretreating and soaking with ammonia works on the buildup (if the fabric is hardened), and I've also pre-treated and soaked overnight with white vinegar for staining (don't mix the ammonia and vinegar). Followed by HOT water wash with a powdered detergent and oxygen bleach (I've had good results with Tide and Persil and use Ecover, too). It can take several cycles depending on how bad it is.

For the deodorant stains, there's a company called Carbona that makes laundry agents for all different types of stains--oil/grease, ketchup/chocolate, grass/dirt, etc. Their formula #9 is for deo/perspiration stains and it works like a charm. You can find them in the laundry aisle of your local grocery store or Wal-Mart.

Hope this helps!
