Good old soap and water - and a brush wouldn’t hurt, for under nails and stuff.
I have a fingernail brush in all the sinks and showers.
It’s more hygienic and dirty fingernails are simply....unattractive.
and clip those sh@t hooks...
For now, I do what I would normally do. I’m already a fanatic nut because of RA / low immunity. I wash everything from the grocery store that can be washed.
Being alert and very careful. Wash my hands more than any doctor/nurse. Wipe handles or wear rubber gloves and dispose after each use.
Take even more precautions.
If it’s your time, it’s your time.
