Andy - I'm only a couple years into my addiction but I'm fortunate to have a double sink in the basement with a hose spigot on it.
Fresh out of the woods the buckets and lids get a full blasting with very hot water and a brush as needed to get them clean and stack them to dry. Over the course of the next few nights and weekends as time allows I'll fill one sink with hot water for a final, full scrubbing and the other has hot water and star san sanitizer (1oz to 5 gallons of water). Only needs about a minute in the sanitizer so while I scrub one, the previous one sits and I spin it a few times while scrubbing then other. I stack them and let them dry for a week before bagging each bucket in a non-scented kitchen trash bag.
I do the same thing pre-season (no bag this round since there off to the woods when dry) and that seems to work well for me.
I've seen bucket washers for sale on FB that have a bucket brush attached to a small motor hooked up inside a cut-out 55 gallon plastic drum that might be interesting to try, but I have the sink and it works.
