Grease trap maintenance isn't just about avoiding a mess — it's often a code requirement, and skipping it can lead to fines, overflows, and unplanned shutdowns.
The General Rule
Most municipalities require grease traps to be cleaned once they reach 25% capacity of trapped fats, oils, and grease (FOG). For a busy kitchen, this often means monthly or even more frequent service.
Factors That Change the Schedule
Kitchen volume, trap size, and the type of food prepared all affect how quickly a trap fills. High-volume fryers and grills generate more FOG than a lighter menu.
Signs You're Overdue
Slow-draining kitchen sinks, odors near the trap, and any visible overflow are signs cleaning is already overdue, not just due soon.
Setting Up a Recurring Schedule
Rather than reacting to a slowdown or overflow, most commercial kitchens benefit from a set recurring schedule that matches their volume and local code requirements — with documentation kept for inspections.
