Grease Trap Cleaning for Illinois Restaurants

Grease trap (grease interceptor) maintenance is a recurring expense for Illinois restaurants—but skipping cleanings can quickly turn that cost into emergency repairs, disrupted service, and potential compliance issues. For owners and operators, the practical question is usually twofold: How often should the trap be cleaned? and What will it cost?

While the exact requirements can vary by locality and facility design, most responsible programs are built around usage-based maintenance. The guiding idea is simple: clean before fats, oils, and grease (FOG) build up to the point where flow is restricted or solids escape into plumbing lines.
