I don’t shave, I just trim it is not an issue.
Lamp and Petitfaun gave me GREAT ADVICE on how to get a good seal:
Newbie can’t get a perfect seal — is continually pumping the pump ok?
As to cylinder cleaning, it is not a big deal at all. Just make sure you do it right after your session, that will make it easier than if you wait and the lube re-congeals.
I use generic KY for lube. So I just rinse out the tube with very warm water after every use.
Then I take a bamboo "back scratcher", put a clean gym sock over the top of it, and stick that in the cylinder and rub the inside to dry it out. (Honestly that is probably an unnecessary step_
I’ve accidently blown a load a couple or three times in the cylinder. In that case I am little more rigorous with the rinsing to make sure every thing gets rinsed out.
