Extractor grease filter

Washable, monthly, with mild soap and water — and the dishwasher permission its maker gives is deliberately not universal.

Precautions

  • Check the manufacturer's instructions
  • Rinse thoroughly afterwards

What this is, what goes wrong with it, and where CleaningHQ can help.

Made from

Aluminium

What tends to go wrong

The science behind this: Alkali attack on light metals

Part of Extractor hood.

In detail

The metal mesh panel that pulls out of the underside of a hood, and the one part of the appliance the manufacturer positively directs a householder to clean. The instruction is mild soap and water, monthly or when the filter status indicator asks. The dishwasher question, which is what people actually search for, gets a carefully bounded answer: MOST grease filters can be placed in the dishwasher for additional cleaning, and the manufacturer directs verifying in the owner's manual for the specific model first. That is a maker declining to generalise about its own products, and it is a better answer than the confident yes or confident no the internet offers. Refitting is directional — one end slides into the opening opposite the tab area, then the other end swings up. This catalogue separately records that caustic degreaser removes the grease and attacks the metal, which is why the manufacturer's mild answer is not timidity: an aluminium mesh does not tolerate the alkalinity that would make the job quicker.

What works

    Soap is safe on, in specific conditions, Extractor grease filter

    Safe only in specific conditions

    This is only appropriate within specific limits. Outside those limits, CleaningHQ makes no claim.

    Only within these limits:

    • Mild soap and water
    • Monthly, or when the filter status indicator asks
    • Refit end-first opposite the tab area, then swing the other end up

    The manufacturer's own interval and its own method. Nothing stronger is authorised, and this catalogue separately records that caustic degreaser attacks the aluminium mesh.

    Precautions

    • Check the manufacturer's instructions
    • Rinse thoroughly afterwards

      Relied on for: That the recommended method is mild soap and water and the interval is monthly or as prompted by the filter status indicator. (states this directly)

      Verification: a person has read the passage relied on.

      Read on The grease filter and charcoal filter sections in full. Supports the claim as stated. Opens the extractor hood as an object with two distinct filter components and a manufacturer behind each. The grease filter gains a positive clearance; the charcoal filter gains a prohibition on cleaning it at all.

    • Only as additional cleaning, not as a replacement for the monthly soap-and-water clean

    The manufacturer says MOST grease filters can go in the dishwasher and directs the reader to verify. A maker declining to generalise about its own products is the honest answer, and it is the one the internet does not give.
