We ran into some pretty bad grease build up during an exhaust hood cleaning at this Cerritos restaurant.
Years of neglect made this a tough clean up but we got it done in one night with a crew of five guys.
This is what one of the exhaust hood ducts looked like before the cleaning

This exhaust system in Cerritos had been neglected for years
After some scraping you can see just how much grease was in the exhaust system.

This pile of grease really shows how much grease was clogging this duct
After a few hours we had the exhaust hood all scraped out

This is what the duct looked like after the years of buildup were scraped out
A foaming degreaser was then applied to break down the residual grease

Foaming degreaser sticks to the walls of the duct and breaks down the grease
The final result was a grease free, fire safe and properly working exhaust hood system with plenty of air flow to this Cerritos restaurant.

This grease duct is now clean to bare metal and is in proper working order
This is how much grease we cleaned out of this Cerritos exhaust hood system

We pulled around 100 pounds of grease out this Cerritos restaurant’s exhaust hood system
