Grease Trap Cleaning2019-07-10T19:19:06-07:00


Grease traps are vital for managing the waste output of any commercial kitchen. When working effectively, grease traps separate fats, oils, and grease (FOG) as well as solid waste from wastewater as it passes through the grease trap. FOG and solid waste are then collected and stored in the grease trap tank.

This allows the wastewater to flow unobstructed from your kitchen sink, dishwasher, or floor drain into your local sewer system with minimal contamination from any food waste.

If a grease trap tank is not regularly cleaned, however, FOG and solid waste will start to pile up, minimizing the effectiveness of your grease trap. While a small amount of oil might not cause any immediately noticeable problems, FOG buildup can cause major and potentially costly issues, especially if ignored.

Some of the issues caused by excess FOG buildup include:

  • Waste Discharge. If the amount of FOG in a given grease trap exceeds 25% of the tank capacity, waste will be able to flow through the trap and into local sewer systems. This could result in city sewer lines becoming obstructed or damaged, as well as local waterways being contaminated, which can incur significant fines/penalties from your city.

  • Sewage and Drainage Backup. Some fats and grease will solidify as they cool, preventing the flow of wastewater. This can cause additional FOG backup and overflow into your kitchen. Backups can also potentially damage your grease trap, necessitating either a repair or replacement.

  • Toxic fumes. As FOG decays, it releases gas that—aside from having a very unpleasant odor—is highly toxic and corrosive. If not regularly cleaned, these fumes will make it back into your establishment, affecting your staff, customers, facility, and overall business.

Can I clean my own grease traps?2019-03-26T18:35:55-07:00

Yes, restaurants can clean their own grease traps. In fact, we provide barreling services for customers interested in self-cleaning.

However, employees often do not clean them properly, or to acceptable city standards. Some cities do allow for self-cleaning with quarterly professional cleaning. Check your local city FOG regulations to see what is allowed.

How often should I have my grease trap cleaned?2019-03-26T21:35:16-07:00

This can vary depending on a number of factors, including industry, city regulations, and customer requirements/availability. Pierce and King County have enacted strict regulations/penalties on how often and thoroughly commercial kitchens clean and maintain their grease traps.

In most cities, it has been mandated that FOG levels in your grease trap tank never exceed 25% tank capacity. For some businesses, this means weekly cleaning, whereas others may only need their traps cleaned on a monthly basis.

My restaurant doesn’t have a grease fryer, why do I need a grease trap?2019-03-26T21:35:42-07:00

A common misconception with some restaurants is that if you do not have a grease fryer, you do not need a grease trap. Unfortunately, this is not true. Even small delis and coffee shops can produce varying amounts of fats, oils, and grease, so it’s vital for every restaurant kitchen to have a grease trap.

What can I do to minimize or slow down the amount of fats, oils, and grease that builds up over time?2019-03-26T21:36:12-07:00

First and foremost, never pour oil or grease down the drain. Try to make sure any food remnants or excess fats and grease are scraped off of plates and into trash receptacles or compost bins, and not into a garbage disposal.

When available, we recommend collecting and recycling used cooking oil. For more information, see our FOG Best Management Practices!
