Methods

What you physically do. Chemistry gets the attention, but contact time, temperature and mechanical action decide most outcomes.

• Absorbent powder treatment

  Lifting an oily mark out of a porous surface with a powder rather than dissolving it with a liquid. The gentlest route on anything water would ruin.

• Blotting

  Lifting a spill straight up into an absorbent cloth rather than working at it. The opposite of what almost everyone does, and the trade bodies are explicit about why.

• Cleaning along the grain

  On a brushed or directional finish, the direction you wipe decides whether marks disappear into the pattern or cut across it permanently.

• Controlled resurfacing

  Removing the marked material rather than the mark. The right answer only where the surface is meant to be renewed, and irreversible everywhere else.

• Descaling

  Dissolving mineral deposits with an acid. Effective, well understood, and the wrong answer on any surface made of the same mineral.

• Dry soil removal

  Taking the loose material away before any liquid touches it. Skipped almost universally, and it is the step that decides whether the rest works.

• Mild abrasion

  Removing a deposit with particles softer than the surface beneath it. Safe or ruinous depending entirely on relative hardness.

• Poultice

  A paste left on a stain for a day or two to draw it back out of a porous material. The only method here measured in hours rather than seconds.

• Pyrolytic (self-clean) cycle

  Burning the soil off at a temperature nothing else in a kitchen reaches. The reason to open a window is more specific than most people are told.

• Rinsing and drying

  The step people skip, and the one that decides whether cleaning protected the surface or damaged it. Residue left behind is exposure that continues after you stop.

• Soaking

  Extending contact time so chemistry can do work that would otherwise need force. Often the difference between scrubbing and wiping.

• Solvent wiping

  Dissolving an oily soil and letting the solvent evaporate. The answer where water would leave a mark or cause harm.
