I am pretty anal with my equipment. I watch it like a hawk...not only for theft reasons but also because people want to stack cues together...no quicker way to get a ding, particularly in the butt section. Shaft dings will drive you crazy, but are easy enough to remove, if done carefully.
I have a cotton flannel cloth that I wipe the butt section down with. A microfiber cloth for the shaft, that I wipe down fairly regularly during play. If you use blue chalk, it won't keep it clean, but will greatly reduce the amount of blueing in the shaft between cleanings. Don't drill your chalk while chalking and you will avoid staining the ferrule. DO NOT leave your cue in your vehicle for whatever reason!!! In fact, I don't even put mine in the trunk. I prefer my back seat. Especially this time of year...the heat will warp out a cue quicker than anything else...and it doesn't take much or very long for this to happen in a vehicle. Even if I have to stop at the store for more than 5 minutes, the cue goes with me. Yeah......I get looks, but could care less.
Caring for a cue at home is much like caring for an acoustic guitar. No storage on an outside wall, store upright. If you can keep the relative humidity inside your home at roughly 47%, you'll be fine.
I actually polish the butt end of my cue with Martin Guitar Polish. It comes in a pump spray bottle, so be careful near the wrap. It uses all natural ingredients and works great...shines that puppy right up! Nothing on the shaft except maybe some SlipStic In a pinch, you can use a piece of an unwaxed brown paper bag to burnish. A nice piece of leather is the best for burnishing. Burnishing will also help minimize dings in the shaft. For a quick surface cleaning of the shaft, I would recommend a Q-Whiz as it will not reduce shaft diameter size or raise the grain, but will take off the icky stuff like powder and oils from your hand.
BTW...especially when it's humid out....I always close my cue case back up after removing my cue for play. This will avoid the material inside the case from absorbing the moisture and retaining it, which can also contribute to cue warpage, not to mention clouding of some cue finishes.
Common sense will get you far with cue care.
