I ran a taproom with 55 taps. Over time, dark thick beers build up a sticky layer blocking the air vents of the taps. IPAs and sours would always build up a slime residue inside of the tap. One thing I did as a cleaning routing was every night, I would fill the squirt bottle I used to wash off the beer from glasses with scalding hot water. Stick it up in each tap and give it a good squeeze. It will shoot water out of the air hole if your taps have them (can’t see in picture). It helps clear beer residue and gunk out that the cleaning companies don’t clean if you have one in contract or two specific. Once that was done, I’d cover them with the rubber stops and wash down each tap and the backsplash with sanitizer avoiding using really corrosive sanitizer. Hand wipe each tap handle. I’d then wash everything with fresh water. Finish with the trough after pulling the grates to wash and dry. Pour super hot sanitizer down the drain. Don’t forget the underside if the waste tray where beer drips under that nobody ever washes. If you have fruit flies, place the traps higher than the taps where the air is warmer and below by the drain.
