Since cleaning is a pet peeve of mine, and the AIO is mostly tubing, I'll share a little technique I use for cleaning my tubing, which I do regularly.
Get a piece of string longer than your tubing and tie a piece of cloth rag onto it, size the strip of rag to fit snugly into the hose. Coiled in the sink, run hot water through the hose to flush it out. While running the water into the hose, feed the free end of the string into the water stream as it enters the hose, this will thread the string through the tube, you can then pull the rag through. Put whatever you want on the rag, cleaning solution, kmeta, dry rag to dry out, etc. Keeps em clean and sparkling.
I also have a couple of tubing cleaners made of a length of electrical wire with the insulation still on it. Same principle, rag on one end, feed the wire through the tube, pull the rag through to clean / dry. When you're done with it, it rolls into a neat little coil for storage.
A little anal? OK, I admit that, but if you've not cleaned the inside of your hoses with any kind of friction / abrasion and they're looking a little dull, you'll be surprised to see what comes out on the rag.
how should I clean?
