Hello,I have a question about nail fungus. Sorry if this is gross. My grandmother has fungus on her nails and she asked me to paint her nails. I didn't want to use the nail polish bottle and do her nails and keep dipping it in, spreading the fungus in the nail polish bottle. Instead, I poured out some nail polish into a cup and then used the nail polish brush to paint her nails. I then washed off the brush with soap and water and put it back into the nail polish bottle. Does washing with soap and water get rid of the fungus, i.e. is the bottle of nail polish that I put the washed brush into safe to use or should I throw it away?Thanks!

Summarized question: Is nail fungus contagious?
