Of all the hassles of traveling -- long airport security lines, weak U.S. dollar, a snoring passenger in the adjacent airplane seat -- stinky clothes probably doesn't top the list.

But for fastidious travelers, it can be a concern. What should you do with your sweat-soaked socks from the hotel gym or that smoke-filled dress you wore to the hotel bar? How do you put the old clothes back in your suitcase without getting your clean clothes dirty?

You could always wash them by hand or track down a dry cleaner, but that can be a hassle.

Or you could stash them in a Universal Deodorizer -- a nifty garment bag, laundry bag or satchel -- to segregate the smelly clothes from the clean clothes. The charcoal-activated bags, made by Flat-D Innovations Inc., suck up perspiration and smoke odors in a few hours.

A test run of a sweat-drenched shirt from running shows that the product does remove a lot of smell. It's not pristine-clean the way it would be if you threw it in the washer, but much better than it was, after putting it in the 19-by-19-inch satchel ($29.95) overnight.

The Universal D is also available in bigger and pricier models, including a 39-inch-tall clothes-carrier garment bag for $69.95 or an 18-by-30-inch laundry bag for $49.95. Or you could just buy a bag of activated charcoal for $3.95 and stick it in a drawer or gym bag.

The bags are reusable if you store them in a plastic bag, so they aren't sucking odors from the open air. And you can wash them a few times.

The company won't say how many times you can use the bag, saying it depends on many factors, including how stinky the item was, how the bag was washed, etc. So you might have to figure out through trial and error if this handy bag is cost effective.
