Squeeze a little section of toothpaste — the kind that has baking soda in it is best — onto your hands and rub them together. After you’ve been rubbing them together for a couple of minutes, wash your hands off with clean water. Pour a small amount of salt into your hands and rub them together. You may want to moisten the salt with some water to improve its adhesion. When finished, rinse the salt away with water and dry your hands. You can also lather your hands up with dish detergent before sprinkling salt on your hands. Scrub them together to begin eliminating the odor, and rinse your hands with clean water once you’re finished. If you don’t mind your hands smelling like coffee, use coffee grounds to eliminate any odors. Cover your hands entirely with coffee grounds and then gently scrub your hands together in a bowl of water. As an alternative, you can also rub whole coffee beans together in your hands until the odor starts to disappear. Mix together 1 part baking soda with 3 parts water in a bowl to create a paste. Rub the paste all over your hands thoroughly for at least 1 minute. Rinse the mixture off with clean water afterwards.

Summary:
Squeeze toothpaste onto your hands to tackle the smell. Rub your hands together with wet salt to create a scrub. Cover your hands with coffee grounds for great-smelling hands. Make a paste of 1 part baking soda and 3 parts water.
