In all seriousness, if I'm on the ball, all the playing kit goes in the bath when I get home to have the paint hosed off with a shower head, the clothing goes in the machine. Markers get a good wipe down, all the paint off and the barrels go in the sink with some very hot water to remove any trace of paint residue etc from inside, then are squeegeed and put away. Mask get a careful sponge down with hot water, with the lens being removed to get paint out from the joins. Be very careful not to get water between the panes of a thermal lens! Pots get cleaned up (they all go in the bath if they're bad). If I'm feeling thorough, I also clean all the old ****ty paint out of the bottom of the kit bag and so on, then put all my allen keys beack in the right spots in the tool box and chuck old batteries etc out.
As I use Egos, they get a quick check and re-lube the night before I next play (and a fresh battery every time to be sure!). My Girlfriends DM8 gets a relube of the bolt just before any event it's used at. If there's been any paint in them, the hopper have the electrics removed and then get cleaned in the sink.
The markers also get an annual thorough strip down and clean, either at the tech tents at campaign or by myself (don't strip your marker totally unless you're very confident, you'll ruin it!)
