In detail
Mild abrasion uses fine particles, suspended in water or carried on a cloth, to break a deposit up mechanically. It is the appropriate technique wherever the soil will not dissolve — carbon and soot being the clearest examples, since no domestic chemistry touches them. The whole safety question reduces to relative hardness. Where the abrasive is softer than the surface, it removes the deposit and leaves the surface unmarked; where it is harder, it removes the deposit and scratches the surface permanently. Fine mineral powders and wood ash sit below glass and glazed ceramic in hardness and above baked-on carbon, which is the specific combination that makes them work on stove glass. The same materials are wrong on soft plastics, painted finishes and polished metal. Two secondary rules matter in practice: work with any directional grain rather than across it, and start with the least aggressive option, since a scratch cannot be undone by a gentler second attempt.
What works
Mild abrasion is effective against Soot Supported
Mild abrasion is effective against Burnt-on food and carbon deposits Established practitioner practice
On a barbecue grate the manufacturer's routine uses heat to soften the deposit first, so the brushing has less to do.
Mild abrasion is effective against Tarnish Supported
An abrasive polish genuinely removes tarnish, and that is precisely why it is dangerous on a plated surface.
Mild abrasion is effective against Mould Supported
A stiff brush, hot water and household detergent. The mechanical part is the part that does the work, and the authorities say so in that order.
Mild abrasion is effective against Algae Supported
Scrape the thick growth off first, and brush the wash in well. Dead growth is then left to weather away rather than scrubbed.

Mild abrasion is appropriate for Oven shelf
Safe in the conditions described
Authoritative guidance supports this combination, within the conditions described below.
A clearance, where the oven's other components all exclude abrasives.
Only within these limits:
- The shelf is removed from the oven, so nothing else in the cavity meets the abrasive
- Rinsed with clean water and dried afterwards, as the manufacturer instructs
- Uncoated metal shelves; a coated or non-stick shelf is a different component and is not covered
The clearance is for the shelf off the appliance. It carries nothing about using an abrasive anywhere inside the cavity, where every other component excludes one.

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, no claim is made.
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
- Mild abrasion is explained by Mechanical action and abrasion
When the obvious answer is wrong
How do I remove limescale from a marble shower without ruining the marble?
Marble is also calcium carbonate. The acid cannot distinguish between carbonate deposited by hard water and carbonate that is the stone itself, so it dissolves both. The result on the stone is etching: a dull, slightly rough patch where the polished surface has been chemically removed. It is not a stain and there is nothing left on the surface to clean off.
A different kind of treatment works: Take the mechanical route rather than the chemical one. The stone trade's stated treatment for surface accumulation of hard water — what it calls water spots and rings — is to buff with dry 0000 steel wool, which is fine enough to lift the mineral film without cutting the stone, and involves no acid at all. Work on the deposit only, keep it dry, and stop as soon as the film has gone. Prevention does more than any treatment here: a squeegee after each use removes the water before it can evaporate and leave its minerals behind, which is the moment the deposit is actually created. If the surface is already dull in patches rather than filmed, that is etching rather than scale, no cleaning method will touch it, and re-polishing is a job for a stone restorer.
How do I get hard water spots off a bathroom mirror without wrecking it?
A mirror is not a pane of glass. It is glass with a reflective coating and a protective backing, and both are exposed at every edge. The glass industry's mirror division states that acid or alkali cleaners can attack the front surface, the edges and the backing, and names cleaners containing ammonia or vinegar specifically as ones not to use. The failure is called black edge, it starts where liquid runs into the perimeter, and it is degradation of the mirror rather than dirt on it.
A different kind of treatment works: Change the mechanism from dissolving to drying. The mirror division's own recommendation is clean warm water on a soft lint-free cloth, wrung out, with the mirror dried immediately afterwards — which works because the deposit is created at the moment of evaporation rather than while the water sits. Apply any liquid to the cloth and never spray it at the mirror, so nothing can run down into the edges, and finish by checking that the joints and edges are dry. Where a mark will not come off with water, the paper's stated method is 0000 oil-free steel wool, explicitly not a solvent, since solvents attack the edges and backing too. The prevention is the whole answer in a bathroom: ventilate, and wipe the mirror dry rather than letting the condensation evaporate on it.
How do I get tarnish off silver-plated cutlery without wearing the plating through?
That sentence is also the problem. Tarnish CONTAINS silver, so removing it always removes a little metal, and abrasive polishes carry corrosive acids as well as abrasive compounds. On solid silver that is a slow recurring cost. On plate the silver is only microns thick, so the same treatment is a countdown - and the museum sheet records how it ends: over-polishing plated silver removes the plating and exposes dull base metal that CAN BE MISTAKEN FOR TARNISH. The reader then polishes harder, on the one area with nothing left.
A different kind of treatment works: Work out which you have first, because the answer diverges and hallmarks are how you tell. On plate, drop down the escalation rather than up it. Both conservation bodies direct a silver cleaning CLOTH as the routine treatment for light tarnish on plain undecorated pieces, and the museum sheet states that a cloth or a dip removes far less surface than a polishing cream does. For heavier tarnish the UK professional body permits a silver DIP, with conditions that are not optional: follow the container instructions, wear gloves, use fresh solution, and rinse thoroughly - dip left in crevices keeps corroding and produces a green crust. Electrochemical cleaners, including the aluminium-foil-and-bicarbonate method, are ruled out by both bodies as a class. The larger answer is to clean less.
Where the sources disagree
Stove glass guidance prohibits abrasive cleaners and recommends ash, which is an abrasive. Which applies?
The two statements use the word 'abrasive' to mean different things, and once that is seen the contradiction disappears. The prohibition is about materials harder than the glass — grit-loaded scouring creams, metal and nylon scouring pads, blades and scrapers — which cut the surface. The recommendation is about a specific powder that is softer than glass-ceramic and harder than baked carbon, which is the exact relationship that lets an abrasive remove a deposit without marking what is underneath. HETAS makes the boundary explicit in the same article by warning separately against large remnants in the ash: coarse unburnt fragments are the hard particles the prohibition is about, and they arrive mixed into the very material being recommended.
What to do: Use fine ash, sieved or taken from the fine layer rather than scooped with clinker in it, on cool glass, and stop if you feel grit. The prohibition on abrasives is not overridden by the ash technique — it is the reason the ash has to be fine.
