Kitchen Exhaust Duct Cleaning

What is Kitchen Hood Cleaning & Why do we need it?

It is a process of removing grease that has accumulated inside the ducts, hoods, fans & vents of exhaust systems of commercial kitchens.

Kitchen exhaust systems collect grease over a time period. Left uncleaned, eventually will accumulate too much grease & if this will be brought together with flame or intense heat, this will result to an extreme fire hazards. Thus, it should be inspected & clean regularly by experts. By keeping these systems working at their best, they will evacuate the smoke and grease out of the building and produce a cleaner, cooler kitchen and better working environment for staff.

What are the benefits of regular maintenance on your kitchen exhaust equipment?

  • Removal of fire hazard for 90% of fire cause starts with oil and grease accumulation inside the duct.
  • Removal of insect-food source. Insects are attracted with the smell coming from the exhaust fan if not in use.  They might enter inside the duct especially when exhaust is in open area.
  • Produces a safe working environment, avoiding food contamination and everybody’s health is at safe.
  • Improve government inspection rating, avoiding any penalty or closure of establishment.
  • Greater energy savings and avoiding unusual sound coming from the fan motor
  • Extended equipment life. Exhaust fan motor and fan belt will last longer if it is always cleaned.

Grease duct cleaning Procedure:

  • If the grease texture is liquid, we use granules and not chemical.
  • If the grease is hardened, we try to do duct cleaning work without chemicals. We only use spatula & different type of brushes.
  • If we cannot remove the grease with spatula and brushes we try to do duct cleaning works with chemical, and we are aware to the possible leak problems.
  • We do the duct cleaning work by hand as much as possible for those which are hard to clean or remove
  • We try different brushes as we work to obtain the entire cleaning procedure.

Required planning procedures

  • The use of video camera to assess and inspect the inner look of the duct.
