I have two parts rigs and will just disassemble and let one soak in ISO-Prop alc and give them a shake now and again until I'm near needing a fresh start again.
I'll then just Q-tip the crevices, run a pipe cleaner thru the tubes, then drop all the pieces into a cup of distilled water and stir them around, then dry them out.
Works for ME !
