Step 1: Gather the Necessary Tools

“As a restaurant operator, you naturally focus on crafting delicious meals. However, it’s crucial not to overlook the importance of your grease trap, where the waste ends up. Neglecting this essential part can lead to serious issues,” shares George Hull, owner of Septic Tank Cleaning Langley BC, a trusted vacuum truck and septic system service provider for residential and commercial customers in the Greater Vancouver area.

With his extensive hands-on knowledge, Hull’s advice on sanitation maintenance has become invaluable to many in the food service sector.

Before diving into the cleaning process, ensure you have all the essential tools.

You’ll need protective gloves, a bucket or container to collect the grease, a long-handled brush or scraper, and a grease trap cleaner or a mixture of hot water and degreaser [1].

Step 2: Turn off the Water Flow

Begin cleaning by turning off the water supply to the sink the grease trap serves. This prevents the trap from filling with water during cleaning, making the process more manageable and efficient.

Step 3: Access the Grease Trap

Locate the access lid or cover for the grease trap. Most grease traps are near the sink or dishwasher. Carefully remove the lid to expose the trap.

Step 4: Remove Solid Grease

Remove any solidified grease and debris from the trap using a long-handled brush or scraper. This step is essential to prevent clogs and ensure optimal performance.

Step 5: Scoop Out the Grease

Put on your protective gloves and use a scoop or spoon to transfer the collected grease and FOG into the bucket or container. Properly dispose of this waste, following your local regulations.

Step 6: Clean the Trap

With the solid grease removed, it’s time to clean the grease trap thoroughly. You can use a commercial grease trap cleaner following the manufacturer’s instructions.

Alternatively, a mixture of hot water and a degreaser can be effective. Pour the cleaning solution down the trap and let it sit for the recommended duration to break down any remaining residue.

Step 7: Rinse and Reassemble

After the cleaning agent has done its job, flush the trap with hot water to wash away any loosened grease and cleaning solution. Once the trap is clean, reassemble the access lid or cover it securely.

Step 8: Regular Maintenance

Consistent maintenance is crucial to keeping your grease trap in top condition. Establish a cleaning schedule based on your restaurant’s size and cooking volume.

Regularly monitor the trap’s condition and clean it accordingly to prevent clogs and ensure optimal performance.

While the cleaning interval may vary based on the restaurant’s size, cooking volume, and local regulations, a general guideline is to clean grease traps [2] at least every three months. 

However, high-traffic establishments or those with heavy FOG production may necessitate more frequent cleanings, possibly every month.

Conversely, smaller restaurants with minimal FOG accumulation can extend the interval to six months.
