How to clean your hood system yourself before calling us


Maintain a clean kitchen, promote safety and keep your utility bills under control by making baffle hood filter cleaning a top priority. Depending on your cooking volume, this maintenance task should take place monthly, weekly, or even daily. Here are three cleaning methods you have to choose from:


Hand or power washing


This is an effective, all but tedious way to clean baffle grease filters. Follow these steps to clean a filter by hand.

  • Remove filter from the hood safely using a hood filter lifting tool
  • Place the filter in a sink filled with hot, soapy water. An alternative is to take the filter outside and power wash it.
  • Scrub with a non-abrasive sponge or scrubber. Avoid bleach and other harsh chemicals, since they can corrode the metal.
  • Dry the filters immediately after hand or power washing them and reinstall them in the hood.



Save time be cleaning filters in the dishwasher. This method works well with hinged hood filters. Follow these steps:

  • Remove a baffle grease filter from the hood.
  • Open the hinged filter and place it in a high-temperature dishwasher.
  • Fill the soap compartment the way you would if running a load of dishes. To avoid corrosion, never use bleach or harsh cleansers.
  • Make sure all residue is removed from the filter after the washing cycle is complete.
  • Dry the filter completely and reinstall it in the hood.



A hood filter soak tank is an investment that saves both time and labor in the baffle hood filter cleaning process. Follow these steps to effectively soak your filters:

  • Fill a soak tank with water, stopping 6 inches below the top of the tank.
  • Add a non-corrosive, metal-safe cleaner designed for baffle hood filters.
  • Remove the filter from the hood and wipe off excess grease with a paper towel.
  • Place up to six filters in the soak tank and allow them to soak overnight.
  • In the morning remove the filters from the tank, rinse them clean and they’re ready for immediate use.

What NOT to do with your hood system


How NOT to clean your hood system


It is recommended not to clean your hood system yourself. You should call a professional to clean it. While it may be tempting, resist dumping the filters into the dishwasher. Caked-on grease can get released into the dishwasher, clogging its drain, and the filters metal housing can hang around during the cleaning cycle and leave marks on your dishes. Using a household cleaning spray or degreaser for regular clean-up of the outside of the vent is fine. Just remember to use a non-abrasive variety of cleaner. Do not spray the cleaner on the light bulb or any other electrical components.
