Hire someone ELSE to clean it!

Zina's absolutely serious. It's non-sudsing and seems to be well-documented.

There's a trick I've read about: You need 2 cartridges. Someone sells PVC canisters that you slide the filter into, add water and Cascade, then close, seal and forget about. When the one you are using is dirty, you pull the one out of the canister, hose it off, pop it in. The dirty one you hose it off a little, slide it into the canister with fresh water and Cascade.

I don't know where you find these canisters--a Google search may help.
