playing clothes get washed after every game - couldn't contemplate not doing so - eeewwww!
air bottle - thorough check over end of play and before next, and a quick check before every game.
hopper - cleaned outside after each day - inside only if there were breaks.
marker - varies. quick strip, clean and lube initially, but if it's gunked from breaks then a full strip, though clean and nice lubing. the marker reg however only gets done after around 10-12 boxes worth of paint.
