This is a schedule to base on actual use rather than a fixed number of weeks.
Tie it to keg changes
Cleaning the line at every keg change is the guidance most manufacturers actually give — it naturally scales cleaning frequency to how much the dispenser is actually used.
Watch for the symptoms of an overdue line
Persistent foam that doesn’t resolve with correct temperature and technique, or a taste that seems slightly off compared with a fresh keg, both point toward a line overdue for cleaning.
Use a cleaner built for the job
A dedicated, food-safe line cleaner — like KaiserRein’s concentrate, sized for full dispensing systems — is formulated not to leave residue that affects taste, unlike a generic household cleaning product.
Compact sealed systems have their own routine
Systems like PerfectDraft or Krups Beertender typically specify a simpler, manufacturer-defined cleaning process for the dispenser head, separate from a full line-cleaning routine.
What we would not do
Set a fixed monthly cleaning reminder regardless of actual usage. Tie the schedule to keg changes and real use patterns instead — that’s the guidance manufacturers actually give.
What readers ask us
Is there a fixed number of weeks that applies to every dispenser?
No single figure applies universally — the guidance most manufacturers give ties cleaning frequency to usage volume and keg changes rather than a fixed calendar schedule, since a heavily used line accumulates residue faster than an occasional one.
