Grease Trap Cleaning in Lexington, KY

The standard guideline is the 25% rule — a trap should be cleaned when the combined grease and solids layers reach 25% of the trap’s total liquid capacity. In practice, that works out to monthly service for most full-service restaurants and quarterly service for lower-volume operations like small delis or cafes. High-volume kitchens may need more frequent service. We’ll assess your trap and kitchen output and recommend a frequency that keeps you ahead of buildup.

The terms are often used interchangeably, but they technically refer to different sizes of equipment. A grease trap is a smaller, indoor unit typically located under the sink or in the kitchen floor. A grease interceptor is a larger unit, usually installed outside and buried underground, designed to handle higher flow rates. Both work on the same principle — separating grease from wastewater — but they differ in capacity and cleaning requirements. We service both.

We prefer to schedule service during non-peak hours to minimize disruption — early morning before service begins, or after the kitchen closes for the day. For outdoor interceptors, service can usually happen without affecting kitchen operations at all. For indoor traps, we work as efficiently as possible to get in and out without impacting your staff. Let us know your preferred timing when you reach out and we’ll plan around it.

After each cleaning, we provide a service record that includes the date of service, the amount of waste removed, the condition of the trap components, and any observations from the visit. This documentation serves as proof of maintenance for health inspections and is useful for your own records and compliance tracking. Keep these records on file — inspectors typically want to see a service history, not just the most recent visit.

Enzyme and bacterial additives marketed for grease traps are widely available but have a significant drawback — they break down grease into smaller particles that can pass through the trap more easily and cause problems further down the drain line or in the septic system. They may reduce the visible grease in the trap while actually making the downstream problem worse. Regular mechanical cleaning is the approach that actually removes the grease from the system rather than just moving it along.

It makes grease trap maintenance more important, not less. Grease that passes through the trap and reaches a septic tank disrupts the microbial activity that makes the tank function properly. Enough grease accumulation in a septic tank can cause it to stop processing waste effectively, leading to drain field saturation and potentially expensive system repairs. For businesses on septic systems, staying on top of grease trap service is one of the most direct ways to protect the entire wastewater system.
