Commercial Kitchen Hood Filter Care

Commercial Kitchen Exhaust CleaningAre you cleaning your hood filters regularly? Are you putting off cleaning your hood filters until the hood cleaning company comes?

First, be aware that not all cleaning companies offer a complete clean of your filters. They clean the filters by simply wiping them and placing them on the side.

The filters are always cleaned by our team, but if you don’t clean them regularly yourself, your system won’t be as efficient. A large grease build-up can result in your filters becoming rubbery.

A Terrible Example

We were invited to clean the hoods in an Italian restaurant. The owner stated that his hoods should only be cleaned once or twice annually and that the staff would not have to clean them.

The first thing we do when we arrive to clean a hood is to remove all the filters. We then wash them in a separate area. When we checked the filters at this particular restaurant, it was three times the weight they were normally.

The hood filters were being cleaned out by large chunks of hardened oil. We named them “grease worms” due to their shape. We used heated, high-pressure hot water to kill them. It took 4 HOURS just to clean the filter. We even had enough grease worms left over to show the owner of the restaurant.

The filters stopped working and the hood’s interior was filled with grease, similar to what would be found in the duct. The roof had a clogged grease containment. We spent several hours cleaning and repairing the roof.

Price to clean $1500 every six months

Better Way

One of our customers is a fast food burger chain. We have been contracted to clean 27 of their stores’ hoods. This client, however, didn’t own any buildings. Instead, they had stores in strip centers.

The firm had a strict rule: the restaurant kitchen and dining rooms were to be completely demolished and cleaned out every Thursday after close. Part of the plan was to remove all the hood filters.Restaurant Hood Cleaning

When we cleaned their filters, it was a matter of simple degreasing/polishing. This made it easier for us to clean their ducts.
