How to Clean Old Grease from a Kitchen Hood

SAEDNEWS: Old grease on a kitchen hood can become sticky and difficult to remove, but warm water, dish soap, and gentle cleaning can help loosen built-up residue safely.

How to Clean Old Grease from a Kitchen Hood

According to SAEDNEWS, old grease on a kitchen hood is usually easier to remove when it is softened before scrubbing. Start by turning off the hood and allowing it to cool completely. Remove any accessible grease filters according to the manufacturer's instructions, and place a towel or cloth beneath the hood to protect the cooking area from loosened grease and cleaning solution.

A Simple Cleaning Method

  1. Remove loose grease.
    Use a dry paper towel or soft cloth to wipe away surface grease and dust. This prevents loose debris from mixing with the cleaning solution.

  2. Prepare warm soapy water.
    Mix warm water with a small amount of ordinary dishwashing liquid. Dish soap is useful for greasy surfaces because it helps break down oily residue.

  3. Soften the old buildup.
    Dip a soft cloth or sponge into the solution, wring it out well, and place it over particularly greasy areas for several minutes. For removable metal filters, soak them in warm soapy water if the manufacturer's instructions allow it.

  4. Wipe gently.
    Work in small sections using a non-abrasive sponge or microfiber cloth. For stubborn spots, repeat the soaking process rather than applying excessive pressure.

  5. Clean the filters.
    Wash removable filters with warm soapy water when permitted by the manufacturer's care instructions. Rinse them thoroughly and allow them to dry completely before putting them back.

  6. Dry the hood.
    Wipe all cleaned surfaces with a clean, damp cloth to remove soap residue, then dry them with a soft towel.

What to Avoid

Some cleaning methods can damage the finish or components of a kitchen hood. Avoid:

  • Abrasive scouring pads that can scratch metal or coated surfaces

  • Excessive water around electrical controls, lights, or the motor

  • Mixing different cleaning chemicals

  • Aggressive scraping that may damage the hood's finish

  • Reinstalling filters while they are still wet

For grease that has accumulated over a long period, several gentle cleaning cycles may work better than one aggressive scrubbing session. Always check the hood's care instructions before using a particular cleaner, especially on stainless steel, painted surfaces, or specialized filters.
