Could prestidigitation be used to clean poison off an enemy's arrow?

I would allow it but i also doubt it is a good use of your action unless I'm mistaken you are trading a whole action to remove the poison from one attack. And that assumes he doesn't notice it if he does well drawing a new arrow is a free.

I mean this mostly depends on the poison, regular basic poison? Yeah that's not even worth removing.

Purple Worm Poison? Yeah I'd waste an action to get rid of that from some ones weapon.
