Most damage comes from cleaning

A good share of surface complaints that reach service were caused by cleaning rather than by use. Shiny patches on a matt face, a dulled ring around the handle, lifting edge banding: the common cause is the wrong product or the wrong cloth. A door face is not a worktop. Its tolerance for abrasives, solvents and standing water is low.

Before any material-specific advice, one rule covers every surface: remove the dry dust first. Wiping a dusty face with a wet cloth drags that dust across it like fine abrasive, and most light scratching starts exactly there.

Laminate family surfaces

Resin-hardened laminate faces have a closed surface and tolerate cleaning best of all. Neutral soapy warm water and a microfibre cloth are enough. Wring the cloth out; it should be damp, not dripping, because water that runs into the edge banding joint stays there and eventually lifts the band.

For greasy marks, a very dilute washing-up detergent works. Solvents such as acetone, thinners or oven cleaner change the sheen permanently. Steel wool and abrasive pads wear away the printed pattern.

Lacquer and painted faces

Lacquer is a thin, hard shell built in layers. Hard but thin, which is why abrasives are out of the question. Wipe with a damp microfibre cloth and dry immediately with a second cloth. Skip the drying step and, in hard water areas especially, limescale marks are left behind that become permanent.

On gloss lacquer, circular wiping leaves swirl marks visible in raking light, so work in straight passes. On matt lacquer, avoid polishing products altogether: polishing a matt face closes its texture in patches and leaves it looking stained.

Timber veneer

With real veneer, water is the main risk. The cloth should be nearly dry and the wipe should follow the grain. Edge banding and the base of glazing beads are where water collects, so keep a wet cloth away from both.

Veneer is fed once a year. Furniture polish, or the wood care oil the maker recommends, goes on as a thin film with a cloth and the excess comes straight off. Silicone-based sprays look good briefly but build a film on the surface that causes trouble when the finish eventually needs renewing.

PVC facing

PVC foil faces resist water but not heat or solvents. Hot water and steam cleaners can lift the foil at an edge. Warm water with a neutral detergent and a soft cloth do the job. The foil's edge terminations are the sensitive part, so move the cloth from the centre outward rather than catching the edge head on.

Stone and granite textures

Textured faces hold dust in their recesses, and a flat cloth never reaches them. A soft bristle brush, or the brush head of a vacuum, clears the texture far better. A damp wipe follows. Dark cleaning cloths can shed fibres into the texture, so use microfibre.

Glass, handles and metal parts

Door glass takes ordinary glass cleaner, but spray the cloth rather than the pane; liquid sprayed on glass runs down to the bead and sits there. On stainless and plated handles, avoid abrasive metal polish, which thins the plating. A damp cloth and drying are enough, with a touch of neutral detergent for stubborn marks.

Five habits that cause lasting damage

  • Wiping wet before removing dust.
  • Acetone, thinners, bleach and ammonia based products.
  • Abrasive pads, cream cleaners and steel wool.
  • Leaving the surface wet instead of drying it.
  • Pointing a steam cleaner at a faced surface.

A sensible rhythm

On an apartment door, dusting monthly and a damp wipe every three months is enough. A building entrance sees far more traffic, so weekly dusting and a monthly damp wipe is more realistic. In both cases the handle and lock area get attention more often, because that is where hands land.

If you are unsure which material you have, test on a small hidden corner first. If you are planning a new door, weigh the surface against your cleaning habits as well: easy-care faces sit in the laminox two-tone steel doors and white steel doors groups, and textured options in luxury granite steel doors. Send a model and your measurements and the door is quoted as specified.
