Cleaning Procedures for Commercial Kitchen Exhaust Hoods
The exhaust hood in a commercial kitchen can collect a lot of grease and grime if regular cleaning procedures are not being used. The grease that accumulates from cooking in a restaurant kitchen can become very sticky and hard to remove—leaving a major fire hazard in the kitchen.
Cleaning the Grease Receptacles
In order to properly clean a commercial kitchen exhaust hood, several parts must be dismantled. The first step is to remove and clean the grease receptacles. The grease receptacles are easy to remove, as they just slide out from the sides of the commercial hood. Dump any liquid grease that is in the receptacle into a container safe for disposal. Next, soak the receptacle in a mixture of hot water and grease cutting detergent. While the grease receptacles are soaking, begin scrubbing the interior and exterior surfaces of the commercial exhaust hood to remove the baked on greasy residue. After the grease is completely removed, allow the grease receptacles to dry completely.
Cleaning the Filters
Once the grease receptacles are removed, take down the filters from the commercial hood. Allow the filters to soak in a solution of detergent and hot water. This helps to break down the greasy residue and make it easier to remove. Depending on the severity of the buildup, the filters may need to soak for a few minutes, a few hours or even overnight to sufficiently loosen the grease. After soaking, light scrubbing can help to take off the last of the baked on residue. The filters can also be run through a dishwasher for an even more thorough cleaning. Be sure to let the filters completely dry before putting them back into the hood.
Cleaning the Hood’s Surface
Next, start spraying a degreasing compound on the surfaces of the commercial hood. The degreaser will quickly start to break up the residue, making it much easier to wipe off using a soft cloth or nylon sponge. This will effectively remove most of the greasy residue. However, it’s likely that there will be some stubborn spots that will require more vigorous scrubbing to remove the residue. If scraping is required, the best tools are plastic scrapers and nylon sponges, in order to clean the hood and avoid damaging the surface of it.
Be sure to completely rinse the surfaces of the commercial hood after cleaning. It is important to remove all of the chemicals that have been used to remove the grease. Carefully replace the filters and the grease receptacles into the commercial hood after they are fully clean and dry.
