cleaning and storing black tank rinse wand

I assume pouring a final bucket of water over it while it is held in the toilet will rinse the 'stuff' off it (?).

Then What?

I'm thinking I'll then spray bleach on it ( https://www.clorox.com/products/clorox-clean-up-cleaner-bleach/ ) and let it sit outside for 20 minutes or so, then dry it off with a paper towel and put it into a plastic garbage bag in the pass-thru.

There must be a more efficient way to do this!
