Old sweat is smelly sweat, and nothing beats the ripe aroma of a day old T-shirt. The same goes for a suit coat with underarm stains. Get a fresh start every day by taking a shower and making sure your clothes are as clean as you are. One smart option is to install sweat guards on clothes you typically dry clean after multiple wearings. They install with Velcro fasteners, which makes them easy to remove for home laundering. You'll smell fresher and save money on your dry cleaning bills, too.
