This Is How You Should Be Cleaning Underneath Your Fingernails

Bustle recommended that a great first line of defense in keeping your fingernails clean is a good nail brush. It can help you sweep out the dirt and grime without damaging the nail bed or pushing germs further under your nails. That said, one study in The Journal of Hospital Infection did find that the brushes made no difference in the level of bacteria under nails. If using one suits you, though, you should always allow it to air dry after using it to prevent bacteria from growing in it (via Healthline). 

Healthline also suggested that you could lather up with dish soap for especially greasy grime, as the soap specifically cuts grease. The outlet also noted that if your water is too hot, it could dry out your fingernails, so lukewarm water works the best as you suds up. Soaking your hands can also loosen up the dirt (via Bustle). After washing and drying your hands, you should also apply a good moisturizer to prevent them from drying out and getting brittle. 

Ultimately, short, well-shaped fingernails are the easiest to keep clean. However, no matter the length, be sure you scrub your nails at least once a day, or more if they are visibly dirty. If, while cleaning your fingernails, you happen to notice something strange like swelling, redness, or discoloration, be sure to talk to your doctor about the changes.
