Restaurant Hood Cleaning: Everything You Need to Know

March 29, 2024

Ensuring the kitchen is clean and safe is just one of the many duties that come with running a restaurant. An essential part of this is keeping the kitchen hood clean. This task may not be the most exciting part of running a business. Still, it’s necessary for safety, compliance, and efficiency. Learn everything you need to know about cleaning a restaurant hood.

What is Restaurant Hood Cleaning?

Cleaning the exhaust system of an industrial kitchen to remove grease, smoke, and other debris is called “restaurant hood cleaning.” It includes the exhaust fans, filters, ducts, and hood. Keeping things clean is very important for safety because grease and other substances can build up and cause smoke and fire danger.

Why is Restaurant Hood Cleaning Important?

1. Fire Safety

The purpose of frequent hood cleaning is to avoid fires. Grease accumulation is a flammable substance that may cause a massive fire and smoke danger with a little spark, and fire damage can impact your health. Regular cleaning significantly decreases this danger.

2. Health Regulations

Local health standards and regulations usually require regular cleaning of restaurant hoods. Failure to comply may result in fines or possibly closure.

3. Efficiency

A clean hood system operates more effectively, increasing ventilation, lowering energy expenses, and providing a more pleasant working environment for kitchen employees.

4. Air Quality

Regular cleaning improves air quality in the kitchen and dining area, resulting in a more pleasant experience for personnel and customers.

How Often Should Restaurant Hoods Be Cleaned?

How often you need to clean kitchen hoods depends on how much and what type of food you cook. Here are some easy rules:

  • Clean the hoods monthly if your restaurant is open all day or uses wood or charcoal fires.
  • For small businesses, clean the hoods every three months.
  • For places that don’t cook much, like churches or camps, cleaning the hoods every six months is okay.

Remember, these are just basic rules. Your local rules can ask for something different, and you might need to clean more or less often based on your unique situation.

The Cleaning Process of Restaurant Hood Cleaning

Restaurant hood cleaning is required to be performed by professionals who are trained and certified in this specialized task. The process typically includes the following steps:

  • Preparation: The cleaning crew will cover kitchen appliances and floors to protect them from chemicals and water.
  • Degreasing: The team applies a degreaser to break down the grease and grime.
  • Scraping: After the degreaser has done its work, the built-up residue is manually scraped away.
  • Pressure Washing: High-pressure water is used to wash away the loosened debris from the hood, ducts, and fans.
  • Polishing: Finally, the exterior part of the hood is polished, leaving it looking clean and shiny.

Choosing a Hood Cleaning Service

When choosing a service provider for your restaurant hood cleaning, consider the following:

  • Certification: Ensure they are certified by a reputable group, such as the National Fire Protection Association (NFPA).
  • Experience: Look for a company with significant experience in commercial kitchen cleaning.
  • References: Ask for and check references from other restaurants in the area.
  • Insurance: Make sure the cleaning service is covered in case of accidents or damage.
  • Compliance: Confirm that they follow all area regulations and standards.


Regular restaurant hood cleaning is a vital aspect of running a safe and efficient kitchen. By understanding the importance of this process, knowing how often your hoods need to be cleaned, and choosing a qualified cleaning service, you can ensure that your restaurant runs smoothly and safely. Remember, a clean hood is not just a regulatory requirement – it’s a cornerstone of a successful food service business.
