Steel wool

A metal abrasive that scratches most household surfaces and leaves iron particles behind on the rest — which then rust and look like a stain the surface has produced.

In detail

Steel wool is fine steel drawn into shavings, and it cuts. On the surfaces it is right for — bare cast iron, a seized fixing, some raw timber — nothing else works as quickly. On almost everything in a kitchen or bathroom it is the wrong tool for two separate reasons, and the second is less obvious than the first. The first is hardness: steel scratches stainless steel, chrome plating, glass-ceramic hobs, acrylic, enamel and glass, and stainless steel is not exempt simply because it is also steel. The second is contamination. Steel wool sheds particles, and particles left on a surface corrode, producing rust spots that look as though the surface itself has failed — this is the commonest cause of what people describe as a stainless steel sink that has started rusting. The stone trade makes the same point from another angle, warning that fine steel wool leaves iron in a porous stone which then stains it from within. Where fine abrasion really is needed, a non-metallic pad or a cream cleanser does the same job without leaving iron behind.

What works

Steel wool is safe on, in specific conditions, Mirrored glass

Safe only in specific conditions

This is only appropriate within specific limits, and nothing is established outside them.

Only within these limits:

  • 0000 grade, OIL-FREE, for stubborn marks only
  • Specifically NOT solvents, which attack the edges and the backing
  • Finish by making sure all joints and edges are dry

A rare case where the abrasive is the safe option and the solvent is not. The vulnerable part of a mirror is its backing, and a solvent reaches it where an oil-free wool does not.

Precautions

  • Test on an inconspicuous area first

    National Glass Association (NGA), Mirror Division, 2019 · Trade or professional body

Steel wool is safe on, in specific conditions, Oven shelf

Safe only in specific conditions

This is only appropriate within specific limits, and nothing is established outside them.

A sharp boundary within one appliance: permitted on the racks, forbidden on the knobs of the same range.

Only within these limits:

  • The racks only — never the knobs, the panel, the cooktop or the cavity
  • For stubborn residue after liquid detergent or all-purpose cleaner has been tried
  • Rinse and dry afterwards

Steel wool is unsafe on stainless steel and prohibited on the control knobs of this same appliance. The maker allows it on this part, and nowhere else on the machine.

Precautions

  • Check the manufacturer's instructions

Safe only in specific conditions

This is only appropriate within specific limits, and nothing is established outside them.

Only within these limits:
