Barbecue grate

Three different surfaces that look identical under a season of carbon, and the one place on a barbecue where food actually touches metal.

Precautions

  • Do not apply to a hot surface
  • Rinse thoroughly afterwards
  • Check the manufacturer's instructions

In detail

The grate is what people mean when they say they are cleaning the barbecue, and the first question is one they usually cannot answer: what is it made of. Bare cast iron, porcelain-enamelled cast iron and stainless steel are all common, all look much the same once carbonised grease has built up, and all want different treatment. The coated one catches people out. Porcelain-enamelled cast iron is cast iron with a glass coating fired on at manufacture, and the coating IS the surface: it does not need seasoning and never will, which is the opposite of what bare cast iron requires, and it can be chipped by anything with a sharp edge — after which the iron underneath corrodes. Applying bare cast iron's routine to it, or a scraper to either, is how a grate is ruined by being looked after. The routine manufacturers give is heat first, brush second: bring the grill up to temperature, then brush with a stainless steel bristle brush. Heat does the work soaking would otherwise have to. One instruction is food safety rather than maintenance: check a wire brush for loose bristles before every use and replace it annually. A bristle that leaves the brush lands where food is about to be cooked.

What works

    Mild abrasion is safe on, in specific conditions, Barbecue grate

    Safe only in specific conditions

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

    Only within these limits:

    • a brush with stainless steel bristles, not a scraper or anything with a sharp edge
    • check the brush for loose bristles before every use and replace it annually
    • on porcelain-enamelled grates, nothing that can chip the coating
    • the manufacturer's own guidance governs for the grate you actually have

    The loose-bristle check is a food-safety instruction, not brush maintenance: a shed bristle lands on the surface food is cooked on.

    Precautions

    • Check the manufacturer's instructions
    • Do not apply to a hot surface

    Why we say this

    Supported

    Manufacturer guidance for its own grates, carried with its scope attached. It is not extended to stainless steel grates, which this document does not cover.

      Weber-Stephen Products LLC · Manufacturer documentation

      Relied on for: That a stainless steel bristle brush is specified, that anything with sharp edges can damage the porcelain enamel and lead to corrosion, and that the brush should be checked for loose bristles before each use and replaced annually. (states this directly)

      Verification: a person has read the passage relied on.

      Read on The preheat-and-brush routine, the brush guidance and the seasoning statement. Supports a narrower statement — our claim was reduced. Enough to open the family with the material distinction that matters — porcelain-enamelled cast iron is a COATED surface whose coating is the thing at risk, and it is not bare cast iron and must not inherit bare cast iron's seasoning routine, which the register already holds from a cookware manufacturer. Not enough to publish a stainless-steel-grate procedure or a washing-up method, and neither is published. The loose-bristle instruction is carried as a precaution wherever a wire brush appears.

    2. How to Clean seasoned cast iron

      Lodge Cast Iron (Lodge Manufacturing Company) · Manufacturer documentation

      Relied on for: That bare cast iron carries a seasoning layer that is maintained rather than stripped, which is what makes coated and uncoated cast iron different cleaning problems. (background and mechanism only)

      Verification: a person has read the passage relied on.

      Read on The three-step cleaning method, the soap statement, and the rust guidance. Supports a wider statement — our claim was widened. Created the cast iron record and overturned the most widely repeated rule about it: CleaningHQ would otherwise have carried the folk prohibition on soap, and the manufacturer states the opposite with the reason. SPRINT 32 READ THE FAQ BLOCK AND IT ADDED ALMOST NOTHING — soap, soaking, steel wool and the dishwasher again, in question form. The three cast-iron rows it unblocked were unblocked by re-reading OUR OWN STALE NOTES, not by reading more of this source.
