There are many often-overlooked reasons why toenail fungus either comes back or never seems to go away in the first place. If you got it from walking around a hotel shower, a swimming pool deck, or a gym locker room floor, then you obviously know to cover your feet with flip-flops or water shoes. What you may not think of is the fact that fungal spores can live on all kinds of surfaces for months — including metal toenail clippers! So when you cut your fungal nail with your clippers, you can easily transmit the fungi to other toenails or fingernails — and even reinfect yourself — if you don’t properly sanitize your clippers. We’ll give you a few different ways of doing that.
