Here's my hack: Myles is my keg whisperer.
I'm kidding, obvi, but the recirculating keg cleaners (whether DIY or the pre-made ones) are a must. Same with a line cleaner. We can't use the recirculating line cleaner since our taps are so far away from the kegs, but we do pump BLC or Penetrate through the lines as soon as a keg kicks.
Another great tool is a long handled toilet brush. If you don't have skinny arms - like myself - it helps get a scrubby down to the bottom of the keg.
Something I wish I would have done when I set up the draft system was only use MFL fittings and not barbed fittings. We mainly use ball locks but have guest taps from time to time, some of which are pin locks. I've since replaced the barbs with MFLs, but it would have been nice to have the forethought.
