Thats ridiculous, your bong is not for show.

How exactly are you having problems cleaning it? Why do you need to clean it at all? Does the stem get too clogged to pull through?

If you cannot clear it completely then you will most likely have difficulty clear any decent-sized bong, I'd suggest that you consider buying a pipe.

If you are desperate for water-filtration then get a bubbler, which is a tiny little bong-pipe that is no trouble to clear.

But seriously, why is cleaning your bong so vital?
