How to Properly Clean a Range Hood

It’s so easy to ignore a range hood during routine cleaning of your kitchen. This particular device needs thorough cleaning on almost regular basis to keep your house safe from fire hazards, bacteria, and germs.

Range hood is very easy to clean, although you might need proper cleaning chemicals to accomplish that. Depending upon the type of range hood you have, you can either clean or replace the hood’s filter on regular basis. 

1. Washing the Outer Area of the Range Hood

Choose right cleaner according to your hood. These days, range hood are made using variety of materials. Always choose a safe cleaner that does not damage the hood’s material. For example: 

  • For copper range hoods, it’s best to use a good copper cleaner
  • For stainless steel hoods, use a lukewarm soapy water solution
  • For vinyl or plastic hoods, you can use a mild all-purpose cleaner or even a warm soapy water 
  • 1
    Wipe the outer area of your range hood. It’s an easy job since it’s aimed away from your stovetop. Just spray the surface with some cleaner and follow the directions on the pack. If it advises, let it sit there for some time before wiping it off.

    Now, dry the hood. Wipe out using a clean, dry cloth or a simple paper towels. Remove all traces of the hood cleaner. If your hood’s material has an obvious grain, you can wipe this grain for a deep clean and polish. 

2. Cleaning Underneath the Range Hood

  • 1
    You can steam the inner side if necessary. However, first take a peek on the underside. If it’s bit dirty, fill a big pot with some water and boil it on a stovetop. Keep it boiling for about 40 minutes. Let the steam soak deeply into the cut. This will help loosen it from the hood. 
  • 2
    If accumulated dirt is light enough, you can accomplish cleaning using a regular surface cleaner. If it’s heavily greased, you need a tougher degreasing chemical to get the job done. First give a small hood area a test spray before spraying the entire surface. This is important to avoid any adverse reaction with hood’s paint. Again, check the cleaner’s recommendations on which materials it can be used safely. 

Spray and wipe the hood's interiors

  • 1
    Wear safety gloves and open your kitchen windows and turn the exhaust fan on to ensure strong ventilation. Now spray the hood’s interiors as per directions and wipe it down using a cloth, sponge, or maybe paper towels. 
  • 2
    Many cleaners recommend wiping down the range hood interior immediately. Others may allow letting it sit down for few minutes so it can easily soak grease, dirt, and crud. 
  • 3
    Wipe once again using a wet towel. Strong cleaners can leave odors and streaks if traces are left to linger. Once the interior area is clean, use a clean paper towel or cloth and wipe interiors once again to remove all chemical residue and repeat the process using a dry cloth. 
  • 4
    Repeat this frequently
  • 5
    Clean frequently because job can be tough if you wait longer between each cleaning. It should be a part of your weekly routine when cleaning the entire kitchen. When a particular meal uses considerable oil or causes extensive splatter, immediately clean it afterward, as soon as your stovetop is safe to work around.

It’s best to check it monthly. If the filter appears splattered or stained, plan on cleaning or replacing it immediately.

Can All Range Hood Filters Be Cleaned?

These days, three types of filters are used in range hoods:

  • check
    Metallic grease filters. Metallic grease filters need frequent cleaning. They are usually made of stainless steel or aluminum. They are either baffle filters or mesh filters and rest at the base of range hood.
  • check
    Fabric grease filters. Fabric grease filters absorb grease and fumes and cannot be cleaned. They need regular replacement.
  • check
    Charcoal filters. Charcoal filters are present in many ductless range hoods and their main purpose is to eliminate smoke and odor. They help in recirculating air back into your kitchen. These filters cannot be cleaned. They need replacement every 4-5 months, depending on how often and the kind of meals you prepare. 

Grease filters help in filtering out grease and oil fumes. They are found in all range hoods with exception of few models. 

How to start with range hood filter cleaning?

Range hood filter can be cleaned easily in just an hour.

How to Detach the Range Hood Filter to be Cleaned?

This depends upon your range hood model. However, in all range hood models the process to detach is very easy. Before you proceed, it’s important to switch off your appliance.

Now check the overall setup of your hood. See if metal filters are visible or they are hidden? Remove all protective casing at the base of the hood using a screwdriver. In most hoods, there is no protective casing.

Screws hold filters in place, so you need to unscrew them. Some range hoods may have T-lock mechanism or a metal/plastic fastener that holds them in place. Many models may have rim support where you just have to push the filter up and rote it to set it free.

Most modern range hoods are equipped with dishwasher safe stainless steel or aluminum grease filters.

Check product specifications to find if the filter in your range hood is dishwasher friendly or not. 

If it is dishwasher friendly, simply place it in your dishwasher without worrying about scrubbing or using cleaning solutions. 

4.a. Hot Soapy Water + Ammonia

If you’ve been regularly cleaning your range hood filter every week or month, this simple technique of using just ammonia and soapy water is all you’re going to need.

    Block your kitchen sink and add dish soap, water and some ammonia.

Drying the Filter and Reattachment of Range Hood

Since most filters are metallic, don’t use a blow dryer as this can lead to electric shocks.

The best approach is to allow your filter to dry in time. Put them back in place once they are dry. 

Charcoal and fabric filters can be easily replaced.

So if your range hood has either of them, avoid cleaning them. Simply discard the old one and install the new one.

However, charcoal filters need to be replaced only if they are installed in ductless range hood because when exhaust is being ventilated outside the house using ducts, then you need to replace the charcoal fiter.
