Cleaning a stone benchtop takes warm water, a few drops of mild dishwashing detergent and a soft microfibre cloth — that’s the whole routine for a mineral-surface benchtop, every day of its life. No sealing, no waxing, no special products. Where care gets more involved is with natural stone — granite needs periodic sealing and marble needs genuine discipline — and where it goes wrong is with the cleaners people reach for in good faith: bleach, cream abrasives and alkaline degreasers do more damage to stone surfaces than any spilt coffee ever will. This guide covers the routine, the stain fixes, the products to avoid, and how care differs across every benchtop material sold in Australia.
The daily routine (30 seconds, genuinely)
- Wipe spills when you see them. Non-porous surfaces buy you time — a spill sits on top rather than soaking in — but dried-on food takes scrubbing that fresh spills don’t.
- Warm water, a drop of mild detergent, microfibre cloth. Wipe, then go over once with a clean damp cloth to lift any detergent film.
- Dry with a soft cloth if you want a streak-free finish — mostly an aesthetics choice on darker colours, where water spots show more.
That’s it. The honest secret of a mineral-based surface like NEOTERRA® is that the material does the work: it’s formed under high-pressure compaction into a dense, non-porous slab, so there’s nothing for liquids to penetrate and nothing to reseal — ever.
Weekly reset: the two-minute deep clean
Once a week, or whenever the surface loses its uniform look: warm water with detergent across the whole top, working in overlapping passes; a non-scratch pad (the white nylon type) on any stubborn dried spots; rinse-wipe with clean water; dry. For a streak-free polish on dark or high-gloss colours, finish with a 50/50 mix of water and methylated spirits on a microfibre cloth — it flashes off without residue.
Stain triage: the fixes that work
|
Problem |
Fix on a mineral surface |
Don’t |
|
Tea, coffee, red wine ring |
Warm soapy water; if a shadow persists, a paste of bicarb soda and water left 5 minutes, wiped clean |
Don’t reach for bleach — it can mark the resin component |
|
Oil or grease film |
Detergent-heavy warm water, two passes; the second pass matters |
Don’t use alkaline degreasers (oven cleaner territory) — they etch |
|
Turmeric, tomato, beetroot |
Act fast: soapy water, then bicarb paste if needed. On non-porous surfaces even turmeric sits at the surface |
Don’t let it sit overnight for no reason |
|
Limescale / mineral rings around taps |
A cloth soaked in 50/50 white vinegar and water laid on the mark for 2–3 minutes, then rinsed thoroughly |
Don’t do this on marble — vinegar etches natural marble instantly |
|
Dried cement, grout or paint (renovation) |
Soften with warm water, lift with a plastic scraper held flat |
Never a metal blade or wire pad |
|
Fine scratches / dull patch |
Talk to your fabricator — mineral surfaces can often be re-polished locally |
Don’t attempt DIY polishing compounds first |
The blacklist: what never to use on any stone benchtop
- Bleach and chlorine cleaners — discolour mineral surfaces and strip sealers off natural stone.
- Cream abrasives and scouring powder — micro-scratch the polish; the surface goes dull long before it goes clean.
- Alkaline degreasers and oven cleaners — the fastest way to permanently etch a benchtop.
- Steel wool and metal scrapers — leave metal marks and scratches.
- Wax and “stone polish” sprays on non-porous surfaces — they can’t penetrate, so they sit on top as a smeary film that then traps dirt.
A useful rule: if a product’s label brags about “cutting through” anything, it doesn’t belong on stone.
Heat, knives and the things care can’t fix
Cleaning keeps a benchtop looking new; habits keep it undamaged. Three that matter on every surface, ours included: use trivets under hot pans — thermal shock can mark almost any benchtop surface; cut on a board — knives lose the fight against stone, but they leave marks trying; and don’t stand on the benchtop — point loads over unsupported spans are how slabs crack. None of this is onerous, and all of it is cheaper than a repair.
Why some benchtops never need sealing — and some always will
Sealing exists because natural stone is porous: liquid soaks into granite and marble unless a sealer fills those pores, and sealers wear off, so the job recurs. A mineral surface is different at the material level — the high-pressure compaction process leaves no pore network to seal. That’s not a care tip; it’s a property of the slab. It’s also, quietly, one of the strongest reasons the category took over Australian kitchens: the surface you wipe in year ten is the same surface you wiped on day one, with no maintenance schedule in between.

Renovator’s note: caring for a benchtop you’ve just inherited
Moved into a place with an existing stone benchtop and no idea what it is? Two quick tests before you trust any cleaner to it: drop a little water on an inconspicuous spot — if it darkens the stone within a few minutes, the surface is porous natural stone (or its sealer is spent) and needs pH-neutral products and re-sealing; if it beads and wipes away, you’re on a mineral or porcelain surface and the routine above applies. And if the previous owner left paperwork with a product code — every NEOTERRA® slab carries one — the supplier can identify the exact surface and its warranty status years after installation.
Frequently asked questions
What is the best cleaner for stone benchtops?
Warm water with a few drops of mild dishwashing detergent, applied with a microfibre cloth. For mineral surfaces that’s all you’ll ever need; for natural stone, use a pH-neutral stone cleaner instead.
Can I use vinegar on a stone benchtop?
On a mineral surface, diluted vinegar is fine for limescale marks if rinsed off promptly. Never on marble or limestone — the acid etches natural calcium-based stone on contact.
Can I use bleach or Ajax on a stone benchtop?
No. Bleach can discolour the resin in mineral surfaces and strips the sealer from natural stone; abrasive creams dull the polish. Both cause more damage than whatever you’re trying to clean.
Do stone benchtops need sealing?
Natural granite and marble do, on a recurring schedule. Mineral surfaces such as NEOTERRA® are non-porous and never need sealing or waxing.
How do I get streaks off a dark stone benchtop?
Wipe with a 50/50 mix of water and methylated spirits on a microfibre cloth after cleaning — it evaporates without residue. Streaks are usually detergent film, not damage.
How do I remove a stain that soapy water won’t shift?
On a mineral surface: a paste of bicarb soda and water, left for five minutes and wiped off, handles most marks. If a mark survives that, contact the supplier before trying anything stronger — with the product code, they can advise for the exact surface.
Does using the wrong cleaner void a benchtop warranty?
It can — damage from harsh chemicals is typically excluded from any surface warranty, ours included. The routine in this guide keeps you inside warranty terms; if in doubt about a product, ask before using it.
Closing
The best benchtop care advice is choosing a surface that doesn’t need much. See the NEOTERRA® range in full slabs at our Regents Park showroom, request a sample to test the routine yourself, or browse the range online.
