While regular smokers rarely recognize the lingering smell of brunt tobacco, non-smokers generally detect the scent easily. Smoking jackets and hats work well for protecting the majority of the body from cigarette smoke, but the fingers are often left exposed to the fumes. To rid your hands of this smell, all you really need is some soap, baking soda, and less than a minute of your time.
First, measure 1 teaspoon of baking soda and place the spoon near a sink. Turn on the faucet and set the temperature to warm. Rinse your hands. Pump a few squirts of hand soap onto the palm of one hand and use your free hand to add the teaspoon of baking soda to the soap. Rub both hands together to lather up the soap and baking powder mixture. Scrub around your fingernails and the area between your finger. Scrub your hands for at least 20 seconds. Finally, Rinse your hands with warm water and dry them on a clean towel. If you still smell smoke on your fingers after washing them, rub another teaspoon of baking soda on them and rinse them again.
