If you're handling something with a strong scent, like cooking with fish or pungent vegetables (I'm looking at you, garlic), soap might not get the scent off your skin as well as you'd like it to. Add a tablespoon of salt to your hand soap and scrub for 30 seconds. The salt will help scrub off any residue and also neutralize the smell. Bonus: you can use this tip on smelly feet -- just use soap and salt to stop stinky feet in their tracks.
