I used to be able to dump at home, now I can't. I'm never in full hookups, so it's always a 'dump n run' situation. I do put in a few potty fulls of water after dumping, but I'm struggling a bit with keeping the tanks clean (grey and black both stink, and the black sensors don't work).
I have no idea when I'll dump again, but my next few trips are super light water usage trips (mostly travel, less camping) so it may be a while.
I really miss being able to do a thorough clean out at home taking my time and really getting everything clean.
I might fill halfway with water/Dawn when heading out next trip and dump on my way out of town just to see if it cleans it out. Hate paying to dump, btw. I get it, and understand why the old usual suspects are no longer free (or even open, for that matter), but I don't like it.
