What Appliances Need Exhaust Hood Cleaning & When?

December 27, 2014

Learn how and when to remove grease from your appliances for cost-effective fire risk mitigation.

What Appliances Need Exhaust Hood Cleaning & When?Exhaust hood and duct cleaning is an essential service for commercial kitchens because it helps reduce the risk of fire in the exhaust system. At Flue Steam, we offer two different methods for exhaust hood cleaning: hand scraping and steam cleaning. Depending on your kitchen’s needs, we may need to use these cleaning techniques at different intervals in order to best promote fire safety in your kitchen.

Every 30 Days

In kitchens that prepare a high volume of grilled meats or fried foods, the exhaust hoods on cooking appliances need to be cleaned monthly by hand scraping. Typically, the main appliances that need to be cleaned include ranges, broilers, fryer vats. Depending on the layout of the kitchen, these appliances may have a shared exhaust hood or individual ones.

Every 90 Days

In kitchens that don’t focus so heavily on grease-producing foods and cooking methods, it may be sufficient to get hand scraping for ranges, broilers, and deep fryers much less frequently, perhaps even every 90 days. In other kitchens where hand scraping is occurring every 30 days, these same appliances will most likely need steam cleaning every 90 days.

Every Year

If might surprise you to learn that the exhaust hoods over non-grease creating appliances also need to be cleaned periodically. This includes appliances like steam kettles, soup vats, and even dishwashers. This is because even with proper ventilation hoods over all cooking equipment, minute amounts of greasy vapor still have the potential to escape and adhere to other surfaces. Typically cleaning these other exhaust hoods once per year is sufficient.

Find the Right Cleaning Schedule for Your Kitchen

Of course, the 30-day and 90-day guidelines are just starting points. Your particular kitchen may need more or less frequent cleaning. As long as you keep grease buildup within the level that is considered safe and remain in compliance with your local fire safety codes, you have the freedom to stray from the general guidelines.

At Flue Steam, we can help you establish a cost-effective schedule for your exhaust hood and duct cleaning needs. We do this by using a special industry-approved comb to measure grease deposits on interior hood and duct surfaces. This helps us establish the rate at which grease is being deposited which then determines the frequency at which it needs to be removed.
