And as far as cleaning goes, I've never found it to be anything other than completely trivial with pretty much all the holes I've owned. Rinse it out, mild hand soap, dry inside and out with paper towels. The only exception to this is the lolinco virgo, that one is an absolute bitch and a drying stick+ sponge stick is pretty much mandatory.
