Worktop Care — What Damages the Surface

Maintenance rules for every worktop type: postforming, quartz, acrylic stone, natural stone, ceramic. What to avoid and what to clean with.

Universal Rules for All Worktops

  • Wipe up spills immediately — every material suffers from prolonged water contact
  • Never cut directly on the surface — even granite gets scratched by a steel knife
  • Never place hot items without a trivet — the only exceptions are granite and ceramic
  • Never use abrasive pads or scouring powders on any surface
  • Daily cleaning: damp cloth and a mild washing-up liquid

Postforming and HPL Laminate

  • Daily: damp microfibre cloth, any neutral detergent
  • Stubborn marks: soft sponge with a non-abrasive liquid cleaner
  • Avoid: abrasive powders (Comet, Ajax powder) — they leave dull scratches
  • Avoid: concentrated acids or alkalis — they attack the laminate layer
  • Avoid: prolonged soaking — chipboard core swells, especially at edges and joints
  • Avoid: hot pots and pans — laminate bubbles and delaminates

Acrylic Stone

  • Daily: damp cloth, any washing-up liquid
  • Light scratches: grey Scotch-Brite pad — restores a matte finish
  • Deep scratches and burns: a professional can sand and polish them out
  • Avoid: hot pots and pans — acrylic is soft and will dent or crack
  • Avoid: cutting directly on it — softer than steel
  • Gloss versions lose their shine quickly — matte is more practical for a cooking zone
  • Hard water leaves white limescale — remove with diluted citric acid

Quartz (Engineered Stone)

  • Daily: damp cloth, neutral detergent
  • Dried-on deposits: soak with water, lift with a plastic scraper — never metal
  • Stubborn stains (marker, paint): isopropyl alcohol on a cotton pad
  • Avoid: pots straight from the oven — sudden thermal shock can crack the slab
  • Avoid: concentrated bleach — discolours the polymer binder
  • Avoid: abrasive pads — they scratch the finish coat and it cannot be restored
  • No sealing required, unlike natural stone

Natural Stone (Granite, Marble)

Natural stone is porous. Without proper care it absorbs fat, acids, and water.

  • Daily: pH-neutral stone cleaner — not standard washing-up liquid
  • Sealing: 1–2 times per year with a specialist stone impregnator (Bellinzoni, Tenax, or equivalent)
  • Avoid: lemon juice, vinegar, wine, tomato sauce — acid etches marble in minutes
  • Avoid: general-purpose cleaners containing acid or alkali
  • Avoid: abrasive pads
  • Granite is significantly more acid-resistant than marble; marble in a cooking zone is a bad idea
  • An acid etch mark on marble requires professional re-polishing

Ceramic and Porcelain

  • Daily: any detergent, any sponge except steel wool
  • Hot pots are fine — ceramic does not react to heat
  • Stubborn stains: white vinegar or citric acid solution
  • Grout lines are the weak point: they darken over time; renew with epoxy grout
  • Avoid: metal scourers — they scratch the glaze on edges and in joints
  • Avoid: dropping heavy objects on the edge — ceramic is brittle under point impact

What Damages Every Worktop

ThreatWhy it's harmfulMost vulnerable
Hot pots without a trivetThermal shock, bubbling, crackingPostforming, acrylic, quartz
Abrasive pads and powdersScratch the finish layerEverything except granite
Acids (vinegar, lemon)Etch and break down the surfaceMarble, acrylic, laminate
Prolonged water contactSwells the substratePostforming
Cutting without a boardKnife scratchesAcrylic, laminate, quartz
Chlorine-based cleanersDiscolour the binderQuartz, acrylic

One trivet and one cutting board solve 90% of worktop maintenance problems — for any material. Everything else is surface-specific detail.

What to Clean With: Quick Reference

  • Daily — damp microfibre cloth + neutral washing-up liquid
  • Greasy residue — a few drops of washing-up liquid, leave one minute, wipe off
  • Limescale from water — citric acid 1:10 with water (not on marble)
  • Dried-on stain — soak with water, lift with a plastic scraper
  • Marker or pen — isopropyl alcohol
  • Chewing gum or wax — ice pack to harden, then plastic scraper
