I Am A Nurse Working For A Facility Called Teaching

I am a nurse working for a facility called Teaching Living Concepts. Some of our residents have mycotic toenails and we will be getting them in to see a podiatrist, but would like to do some topical treatments so they don't get soooo out of hand. I was wondering if you have any recommendations for TOPICAL (my boss does not want to do the oral treatment) treatments?
Thanks
