How to get a bad smell off your hands
Wash your hands with soap and cold water.
Always use cold water for this, as hot water can dilate your skin's pores and let the odor-causing oils and dirt penetrate further. Create a nice lather with the soap and scrub your hands together thoroughly before rinsing them with cold water.
Splash your hands with antiseptic mouthwash. In addition to neutralizing odor-causing compounds, mouthwash can kill the bacteria on your hands that can cause odor.
