Probably the autism in me but I’d just tell him to use soap

talk about how gross it is to see someone else not wash their hands. ‘that guy came out of the restroom so fast i bet he didn’t even wash his hands, nasty dude getting dick germs everywhere and getting us sick so he doesn’t have to take thirty seconds to wash’

I’d nickname them poopy hands and refuse to touch the same things. I have ocd also tho so that’s prob why lol you can also send them a video of bacteria being transferred around. That’s how I got my partner to close the toilet lid when they flush lol
