How hard is it that people are getting stuff on them? Is the hose too short and they use their hands to bridge the last few inches?
Unless you have a hose give way or some other oddity (where gloves won't help anyway), you don't get anything on your hands. If you are worried about possible migration of germs to the outside of the hose, first most die off fairly quickly so the week or more the hose has sat, they've mostly died off. And they can transfer to the inside of the gloves very easily (even with careful removal).
Worst case, just wash your hands.
I'm glad I grew up on a farm and never got germaphobia.
