My favorite clean up "tool" is the Lysol Dual Action wipe. (I just ordered and received a year's supply from Walmart.) One side is textured and the other side smooth. A brief scrub with the textured side removes the "leftovers". I use rubber gloves (sometimes). Other times I just take care to thoroughly wash my hands. There is no easy answer, I'm afraid. Lucky me lives alone and NO ONE BUT ME uses my toilet! Guests use the bathroom which is NOT adjacent to my bedroom. I never use that bathroom.
