At Bryan Exhaust Service, we’ve encountered a wide range of kitchen exhaust system issues, but every now and then, we come across a real challenge. That was the case last week when we tackled a restaurant kitchen exhaust system in Sylmar, CA. This system was so clogged with rock-hard grease that it required chiseling, foaming, and washing to restore it to a functional state. In this blog post, we’ll share the story of this nightmare job and how our team persevered to achieve remarkable results.

The Distress Call:

When the customer first contacted us, they described a dire situation: their predecessor had left the kitchen exhaust system in a terrible state. The customer wasn’t even sure if the system was functioning. They mentioned turning on the switch and hearing the motor come on, but when they held a napkin over the grill, it didn’t get sucked up. They suspected the system was simply gunked up with grease.

The Grueling Cleaning and Restoration Process:

Our team arrived at the site, prepared for the daunting task ahead. We discovered that the grease buildup in the system was so severe that it had become rock-hard, requiring us to chisel it out before we could proceed with our standard cleaning process.

Armed with chisels and determination, we spent hours prying huge chunks of grease from the system, creating piles of petrified grease on display. It was a labor-intensive process, but our team was committed to restoring the kitchen exhaust system to optimal performance.

Once the majority of the hardened grease was removed, we proceeded with our tried-and-true foaming and washing process. This step was essential in ensuring that all remaining grease and grime were thoroughly cleaned from the system.

The Reward: A Fully Restored Kitchen Exhaust System:

After several hours of hard work, our team was able to transform the grease-clogged system into a fully functional kitchen exhaust. The restaurant owner was thrilled with the results, knowing that their kitchen was now operating safely and efficiently.


Regular maintenance and cleaning of kitchen exhaust systems are critical to avoid situations like the one we encountered in Sylmar, CA. Proper care not only ensures optimal performance but also prevents potential hazards, such as fires, that can result from poorly maintained systems.


The Sylmar, CA project was a true testament to the dedication and perseverance of our team at Bryan Exhaust Service.
