I work in a machine shop I’m 25m. I have weird nail shape even when I cut them they get these corners and since I’m a machinist I get dirt under them. I use a mail brush but it doesn’t get all especially where the nail meats the cuticle where I also get these corners. Should I just started get manicures? Also I have to wear these thick boots everyday do to work is there a way to keep my feet from stinking?
