But lemon juice isn't the only citrus-based solution out there. You can also try using orange juice or grapefruit juice to eliminate the smell. The acidity in these juices will help break down the fishy molecules and leave your hands smelling fresh and citrusy. Just be sure to rinse thoroughly to avoid any sticky residue.
Another weird but effective method is to use toothpaste! That's right, the same stuff you use to clean your teeth can also be used to deodorize your hands. Just apply a small amount of toothpaste to your hands, rub it in, and then rinse with cold water. The abrasive particles in the toothpaste will help scrub away the smell.
