How to Clean a Grease Trap
Grease traps are designed to do just what the name implies, which is to trap fatty oils, greases, and sludge, and to separate the oils from water. The substances pass through a catching system, which gives them time to cool off and solidify, and the water passes through the drain as normal. This system must be maintained regularly in order to work effectively in keeping your grease trap clean. When done correctly, learning how to clean a grease trap will save you ample amounts of money for your business. 

Grease Trap Step 1

Step 1: Detach the lid from the grease trap gently with a pry bar. Be sure to go slowly through this process, as there are gaskets for the grease trap located just under the cover. If you damage these, you will have to spend money to replace them.

Step 2: Inspect the grease trap’s parts once the lid is removed. You will be removing and replacing parts during cleaning, and you need to know where the components are located and how to install them to put them back in properly.

Step 3: Using a small bucket or ladle, skim the top layer of grease and fats from the interceptor. Gently guide it to the bottom of the trap, and swirl it lightly in the trap so that the grease and oils mark the dowel. This can provide you with a guide to how much debris is in the trap. If the amount of grease in the bottom of the trap exceeds 25 percent or one-fourth of the volume, the cleaning frequency should be increased.

Step 5: Remove the waste from your grease trap with the small bucket. Scoop the bucket into the trap, and bring out the solidified waste. Place the waste in a water-tight container, such as a heavy-duty plastic trash bag.

Step 6: Scrape down the lid and the sides of the trap. Remove any large pieces of fat or oils that are attached to the trap. To achieve an even cleaner trap, you can use a wet/dry vacuum to suck out any smaller bits of waste.

Step 7: Clean the lids, trap sides, and parts with soap and room-temperature water. DO NOT USE DEGREASERS IN THE GREASE TRAP. Use a steel pot scrubber to remove excess waste and odor. Flush the screens and parts with water to remove the soap and debris.
