If you run a commercial kitchen, restaurant, or food service operation, you’ve probably wondered how to keep your grease interceptor in top shape. Grease interceptors, also known as grease traps, prevent fats, oils, and grease (FOG) from clogging your plumbing and causing expensive backups. But how often should you clean them, and why is professional maintenance essential? Let’s break it down.
What Is a Grease Interceptor and Why Does It Need Cleaning?
A grease interceptor is a plumbing device installed between kitchen drains and the municipal sewer system. Its job is simple: capture FOG before it enters the sewage line. Over time, grease accumulates in the interceptor, reducing its efficiency and potentially creating foul odors or even plumbing blockages. Regular cleaning keeps your kitchen compliant with local regulations and prevents costly emergency plumbing repairs.
How Often Should Grease Interceptor Cleaning Be Performed?
The frequency of grease interceptor cleaning depends on several factors:
- Size of the interceptor: Larger interceptors hold more grease and may require less frequent cleaning.
- Volume of food waste: Busy kitchens generate more grease, meaning more frequent service is necessary.
- Local regulations: Some municipalities require grease interceptors to be cleaned every 90 days or less.
Most commercial kitchens schedule professional cleaning every 1–3 months to maintain optimal performance. Waiting too long can result in overflows, unpleasant odors, and fines from health inspectors.
What Does Professional Grease Interceptor Cleaning Involve?
Professional cleaning ensures the job is done thoroughly and safely. The process typically includes:
- Pump Out – Removing all accumulated grease and solids from the interceptor.
- Scraping and Washing – Cleaning the interior walls and baffles to prevent residue buildup.
- Inspection – Checking for cracks, leaks, or other damage that could compromise efficiency.
- Documentation – Providing a service report for compliance with local health codes.
DIY cleaning may remove some grease but often leaves behind residue that continues to cause problems. Hiring a licensed service ensures the interceptor works effectively and reduces liability.

- Extends equipment life – Regular cleaning reduces wear and tear on your plumbing system.
- Complies with regulations – Maintains compliance with health and safety standards.
- Reduces odors – Eliminates the buildup that causes foul smells in kitchens.
