How to clean sealed stone without wrecking it.
Warm water, a pH-neutral cleaner and a soft cloth or brush. That is the whole routine, and it keeps a sealed surface protected for years. The vinegar, citrus sprays and lime-scale removers people reach for are the exact things that strip a seal and etch the stone underneath.
The short answer
Clean it gentle, and clean it often.
To clean sealed natural stone safely, use warm water and a pH-neutral cleaner with a soft cloth, mop or soft-bristle brush, then rinse. Skip anything acidic (vinegar, lemon, citrus sprays, lime-scale and grout cleaners) and anything abrasive (scouring pads, cream cleansers with grit, wire brushes). Wipe spills as they happen. A little-and-often clean does more to protect the surface than an occasional hard scrub ever will.
Sweep or dust off the grit first
Sand and grit are abrasive, and dragging them around under a mop is what actually wears at a coating over time. A quick sweep or dry dust before you wash is the single most protective habit there is, indoors and out.
Mix warm water with a pH-neutral cleaner
A stone-safe neutral cleaner sits around pH 7, so it lifts dirt without attacking the seal or the stone. A little mild dish soap in warm water works for a quick clean too, as long as you rinse it off so it does not leave a film.
Wash with something soft
A microfibre cloth, a flat mop or a soft-bristle brush for textured pavers. Let the cleaner do the work rather than scrubbing hard. Steer clear of scouring pads, steel wool and anything gritty, which scratch the surface and the coating.
Rinse with clean water
Rinse the cleaner off with fresh water so nothing dries on and leaves a residue, then let it air-dry or wipe it down. On indoor floors and benchtops, a dry buff leaves it clean and streak-free.
Deal with spills as they happen
A seal buys you wipe-up time, so use it. Blot spills rather than smearing them, and get to anything acidic (wine, juice, cordial, coffee, cola) straight away, because on carbonate stone acid marks the surface itself if it is left to sit.
What quietly wrecks it
The cleaners that do the damage.
Most sealed stone that comes to us looking tired was not worn out by use. It was cleaned wrong. Three things do nearly all the harm, and the trouble is they are exactly what the internet tells you to reach for when a surface looks grimy.
Avoid · 1
Acids
Vinegar, lemon, citrus sprays, lime-scale and mould removers, tile and grout cleaners, and brick or driveway acid. On carbonate stone like limestone, travertine and marble these dissolve the surface itself, so they strip the seal and etch a dull mark into the stone that no coating can put back. This is the big one, and it is the most commonly given bad advice.
Avoid · 2
Abrasives
Scouring pads, steel wool, cream cleansers with grit, wire brushes and stiff nylon scrubbers. They physically scratch the coating and the stone, and on a honed or polished surface they leave a scuffed, dull patch. If a mark will not lift with a gentle wash, the fix is a stronger stone-safe cleaner and patience, not more force.
Avoid · 3
Harsh strippers and solvents
Heavy-duty degreasers, oven and drain cleaners, neat bleach and paint strippers. These are far stronger than a stone surface needs, and constant use of aggressive chemistry shortens any seal's life. Reserve them for the job they were made for, keep them off your stone, and rinse fast if one splashes.
The pattern to remember: anything sold to blast, strip or descale is the wrong tool for sealed stone. Neutral and gentle wins, every time.
Why gentle cleaning matters
The protection lives at the surface.
A good stone seal is not a film sitting on top and it is not soaked away down the pores. Ours anchors into the mineral and pore structure and does its work right at the surface, which is exactly where your cleaning happens too. Look after that surface and the seal keeps working. Attack it with acid or grit and you are cleaning off the very thing protecting your stone.
A neutral clean works with the seal
Because dirt sits on the sealed surface instead of soaking in, a gentle wash lifts it off without touching the coating. The marks that used to set in for good now tend to wipe up, which is the whole point of sealing in the first place.
Acid attacks the seal and the stone together
An acidic cleaner does not politely clean the grime and stop. It reacts with the coating and, on carbonate stone, with the calcium in the stone underneath, so one wrong bottle can undo years of protection and etch the surface in a single wash.
The coating still breathes, so let it
Ours protects the surface while letting moisture escape, which is why it does not trap water and flake the stone. Flooding it constantly with harsh chemistry works against that balance. A simple neutral routine keeps everything doing what it should.
The honest limit
A seal buys time. It is not acid-proof.
Cleaning gently protects the seal, but it is worth being straight about what the seal itself can and cannot do, so you know where the real risk sits and why the neutral routine matters so much.
Acid still etches carbonate stone
On limestone, travertine and marble, no penetrating sealer stops acid etching, because the acid reacts with the surface itself without needing to soak in. Sealing slows absorption and buys you wipe-up time, but a splash of wine or a squirt of citrus spray left to sit will still dull the surface. That is exactly why acids stay off the cleaning list, not just off the dinner table.
More resistant, not immune
Our coating stands up to routine neutral and alkaline cleaning far better than an ordinary sealer, because it is inorganic and sits where the wear happens. It is built to survive normal cleaning for years. But more resistant is not proof against everything: constant harsh chemistry and heavy abrasion still take a toll. Clean it kindly and it keeps working; that is the deal with any real surface.
The real questions
Cleaning sealed stone, answered.
What is a pH-neutral cleaner, and can I just use dish soap?
A pH-neutral cleaner sits around pH 7, so it is neither acidic nor strongly alkaline and it lifts dirt without attacking the seal or the stone. A stone-safe neutral cleaner is the reliable choice. A small amount of plain, mild dish soap in warm water is fine for a quick clean, as long as you rinse it off so it does not leave a film. What you avoid is anything acidic, and anything sold as a heavy-duty, scale or grime stripper, because that is where the damage comes from.
Can I use vinegar or lemon to clean my sealed stone?
No. Vinegar, lemon, citrus cleaners and lime-scale removers are acidic, and on carbonate stone like limestone, travertine and marble the acid dissolves the surface itself. It strips the seal and etches the stone underneath, which is a physical dull mark in the stone rather than a stain sitting on it, and no sealer stops that. The trick that gets recommended online for hard water and lime is the exact thing that wrecks a sealed carbonate surface. Use warm water and a pH-neutral cleaner instead.
Can I pressure wash sealed natural stone?
Gently, and from a sensible distance. A wide fan tip held back from the surface at a moderate setting is fine, and our coating is built to survive normal cleaning. What you avoid is a narrow jet held close on full pressure, which can wear at any coating, drive water into joints and chew soft stone. For most sealed stone, warm water, a pH-neutral cleaner and a soft brush do the job without a pressure washer at all.
Will regular cleaning wear the sealer off?
Not the way harsh cleaning does. Grit left on the surface is abrasive, so sweeping it off before you wash is what actually protects the coating. Ours anchors into the mineral and pore structure and is built to survive routine cleaning, so a pH-neutral wash keeps it working rather than wearing it out. It is the acids, the scouring pads and the heavy-duty strippers that shorten a seal's life, not a normal wash. When the beading does eventually fade, a top-up goes on clean with no stripping. There is more on that in how often you should reseal.
Does sealed stone still stain or mark?
A seal changes the odds heavily in your favour, but it is more resistant, not immune. Because oil, wine and grime sit on the surface instead of soaking straight in, spills that used to set in for good now tend to wipe up, especially if you get to them promptly. Acids are the exception on carbonate stone: they etch the surface itself, so wipe those as they happen. Sealing buys you time and easy clean-up; it does not make stone acid-proof. If yours is already marking or going pale, see why limestone goes white.
