I have worked with solvents, asbestos, lead, etc for a lot of years, wash up after working with anything nasty, so, yes, after a range trip, before and after reloading, after cleaning weapons, etc.
Can't say I do when I am just loading a mag, or unloading a mag, or because I touched a round or loading component, but then again I usually unload at the range and touch components when reloading, so when I clean up after that counts.
Wet wipes in my range bag along with a first aid kit. I rarely used hand sanitizer in the past, always figured I had been exposed to so many things in 60 years that this is what kept my immune system healty.
These days seems I am using it all the time - even old dogs can learn.
YMMV
