I don’t think people necessarily need to douche with toys. You may need to clean it a couple times before you start seeing dirtless exit and reentry but that’s not really a mood killer for me for solo play.
If I was engaging with OH, I would simply get the dirty play out of the way before we planned to have out session.
I’ve read negative health effects on anal douching too frequently. So I typically just lube up, get in there, do a check after exiting, clean if necessary, and repeat.
Haven’t had to clean a toy more than 2-3 times before I can bounce like a porn star on my toys and see nothing extra left behind.
