5 Simple Tricks to Get Rid Of Smelly Food Odors on Your Hands
Lemon juice can help neutralize odors from pungent foods. This works especially well with fish because citric acid turns the amines that cause that fishy odor into ammonium salts that aren't as offending to your nose. Try rinsing your hands in a mixture of lemon juice and water after washing, or just rub half a lemon over your fingers and cutting surface.
Got a stainless steel pan or faucet? Rub your hands on it or wash a few pieces of stainless silverware to get rid of nasty smells. Or, you can buy a bar of stainless steel "soap" made specifically for this purpose. According to Wikipedia, "scientific evidence of its efficacy appears lacking," but a lot of home cooks swear by it, and it can't hurt to try!
This is one of my personal favorite, but it could just be because I love coffee. Just rub coffee beans or grounds on your hands until the smell is gone, and then wash them with soap and water.
If you're not a fan of the smell of coffee, though, you should pass on this trick. You may get rid of the garlic smell, but sometimes washing isn't enough to take care of coffee, so you'd just be trading one smell you hate for another.
What can't you do with baking soda? Not only does it make a great universal cleaner, it's also an excellent odor neutralizer. Add about a teaspoon to some hand soap and scrub as usual.
You can remove scratches from CDs and clean your headlights with toothpaste, and it turns out you can also use it to remove odors from your hands. Just wash your hands with the stuff, then once more with soap (unless you like that minty smell).
