Complete Guide for Cleaning and Maintaining Grease Traps in Commercial Kitchens

As a food establishment manager, you understand the importance of maintaining the grease trap. While getting rid of the accumulation of fats, oils, and grease (FOG) is a difficult task, it is essential and must be done regularly. Grease traps serve an vital function, preventing FOG from being washed down the drain. If FOG builds up down the drain, it can damage the plumbing and sewer systems and harm the natural environment. Commercial kitchens are mandated to have grease traps to prevent this, and businesses may be fined for violations.

Guide for Cleaning a Grease Trap

1. Locate the Grease Trap

Grease traps are typically located inside the building or outdoors. External grease traps can often be identified by their manhole covering or septic tank-like appearance. When inside, grease traps are commonly located in the basement (directly below the kitchen), under the kitchen sink, or beneath a metal flash plate. Once you find the grease trap, identify its size. Knowing the size helps determine if you need specialized equipment for cleaning or if it's small enough for in-house staff to clean. Grease traps between 500 to 2500 gallons require professional tools and experience, while smaller ones can typically be cleaned by permitted restaurant personnel.

2. Work with Cool Water

Using cold water helps fats, oils, and grease to rise to the top. Allow ten minutes for the water from the dishwasher or sink to reach a cooler temperature before beginning. Carefully lift the grease trap cover with a crowbar. Be cautious, as the gasket can be easily damaged. If the cover is bolted, you may need a wrench. Plastic lids are simpler to handle, as they snap off. After removing the cover, you'll likely encounter a dense layer of sludge. Use a scoop to remove the floating grease. Once the FOG is removed, residual water and food particles will remain. A powerful shop vac is helpful to remove these leftovers. Be sure the sinks and dishwashers are not in use to avoid the trap overflowing while you work.

3. Clean the Grease Trap

The next step is to thoroughly scrub the sides, baffles, and lid of the grease trap. A shop vacuum is necessary to remove any stubborn grease stuck in the corners. For a more complete clean, use a scrubber or steel wool, dish soap, and slightly warm water. Properly scrub the interior and exterior, and rinse the soap and debris out with fresh water. Once done, you should have a sparkling grease trap. Perform this cleaning regularly to keep it in good condition.

4. Test for Blockages

Once the trap is cleaned, it is essential to inspect the drain for clogs. Run a gallon of clean water from the kitchen sink to ensure the water flows smoothly without any resistance. If water doesn't drain properly, you may need to call a licensed plumber to clear the obstruction. Once the area is clear, put back the lid and baffle to close the trap properly.

5. Safely Dispose of the FOG

Disposing of the collected fats, oils, and grease (FOG) should be done in a responsible manner. For smaller amounts, use double-lined garbage bags to dispose of the FOG in the local dumpster. An easy method is to mix the FOG with kitty litter to make it easier to manage. For large quantities of grease trap sludge, it’s best to contact a professional for proper disposal.
