Two rules cover most hard floor damage in homes. Water is the enemy of most of them, and acid is the enemy of natural stone. Almost all permanent damage comes from using too much water, or from using an acidic cleaner on a surface that cannot take it.
Identify what you actually have before choosing a product. Laminate and engineered wood look similar and behave very differently. Porcelain tile and limestone look similar and could not be more different chemically.
Natural stone: marble, limestone, travertine
Never use anything acidic. These stones are calcium carbonate, and acid dissolves them. That means no vinegar, no lemon, no limescale remover, no bathroom descaler, and no general purpose cleaner that does not explicitly say pH-neutral.
The damage is called etching. It appears as dull patches where the acid has eaten the polished surface, and it is not a stain that can be cleaned off. It is a change to the stone itself, and correcting it means re-polishing by a specialist.
Use: pH-neutral stone cleaner, a damp mop rather than a wet one, and dry afterwards.
Sealing: most natural stone needs periodic sealing, typically every one to three years depending on use and product. Test by dropping water on it. If it darkens within a few minutes, the seal has gone and it needs redoing.
Avoid: abrasive pads, steam cleaners on many stones, and standing water anywhere.
Granite and slate are more acid-tolerant than marble and limestone, but still benefit from pH-neutral cleaning and sealing.
Ceramic and porcelain tile
The most forgiving hard floor. Ceramic and porcelain are fired and non-porous, so almost any household cleaner is fine and acid does not damage the tile itself.
The grout is a different matter. Grout is porous, absorbs soil and discolours, and it is what makes a tiled floor look dirty when the tiles themselves are clean.
For grout: an alkaline grout cleaner, applied and left to dwell, then a stiff brush. Steam works well here. For discoloured grout that will not respond, a grout pen or regrouting is the honest answer, because cleaning cannot restore grout that is stained through.
Sealing grout after cleaning is worthwhile and takes an hour. It substantially slows re-soiling and makes future cleaning far easier.
Solid and engineered wood
Water is the main risk. Wood swells, cups and eventually the boards lift at the seams.
Use: a barely damp microfibre mop with a wood-specific cleaner. The mop should feel damp to the hand, not wet. Never a sopping mop, never a bucket sloshing water onto the floor.
Never use a steam mop on wood. This is worth singling out because steam mops are widely sold and widely used on floors they should not touch. Steam drives moisture into the seams and through the finish, and the damage accumulates invisibly until it does not.
Finishes differ:
- Lacquered and varnished floors have a surface film and tolerate cleaning well
- Oiled floors need oil-specific products and periodic re-oiling. General cleaners strip them gradually
- Waxed floors need wax-compatible products and periodic rewaxing
Maintenance: felt pads under every piece of furniture, mats at doorways, and prompt wiping of spills. Sunlight fades wood unevenly, so move rugs occasionally to avoid a permanent outline.
Laminate
Laminate is a photographic layer under a wear layer on a fibreboard core. The core is the problem: it is essentially compressed paper, and once water reaches it through a seam, the board swells permanently and cannot be repaired.
Use: a barely damp mop and a laminate-specific cleaner. Even less water than wood.
Never: steam, wax, polish, or abrasive pads. Wax and polish leave a residue on laminate that dulls it and is very difficult to remove afterwards.
Damaged laminate boards are replaced, not repaired, which usually means lifting the floor back to the affected board.
Vinyl, LVT and lino
Durable and water-tolerant, which makes them the easiest hard floor to live with.
Use: a neutral cleaner and a damp mop. Avoid strong solvents, which can soften vinyl, and avoid abrasive pads on the wear layer.
Lino specifically is linoleum, a natural product made with linseed oil, and it is alkaline-sensitive. Strong alkaline cleaners damage it, so use neutral products. Genuine lino also benefits from periodic polishing.
Avoid rubber-backed mats on vinyl, which can cause permanent staining and discolouration over time through a chemical reaction with the vinyl.
Concrete and polished concrete
Sealed concrete takes a neutral cleaner and a damp mop. Unsealed concrete is porous and stains readily, particularly with oil, and benefits from sealing.
Polished concrete should not be cleaned with acidic products, since it contains cement which reacts with acid.
General principles that apply to all of them
Sweep or vacuum before mopping, always. Mopping over grit grinds it into the surface, which abrades the finish. This is the most common cause of dull, scratched hard floors, and it is entirely avoidable.
Change the water when it is dirty, not when you finish. Dirty water redeposits soil and leaves a film that makes the floor look worse than before you started.
Two buckets, or a flat mop with a wringing system. One bucket means rinsing your mop in the dirt you just removed.
Mop out of the room, working backwards toward the door.
Doormats, inside and out. Most floor soil arrives on shoes, and a good barrier mat captures a large share before it reaches anything. The cheapest floor protection available, and a mat needs to be long enough for several footfalls.
Felt pads under furniture, and check them periodically, because they collect grit and become the thing that scratches the floor.
Deal with spills quickly, particularly anything acidic on stone or anything wet on wood and laminate.
After building work
New floors have curing rules that catch people out.
Some stone and grout should not be washed for several days after installation. Newly grouted tile carries a cement haze that needs a proprietary haze remover rather than more scrubbing, and using acid on the wrong stone will etch it permanently. Freshly finished wood needs time before any cleaning at all.
Ask the installer, and if you are booking a post-construction clean, tell the contractor exactly what has just been laid.
When to get professional help
Worth it for:
| Work | Typical cost |
|---|---|
| Strip and reseal vinyl or lino | £3 to £7 per m² |
| Machine deep clean, tile | £1.50 to £3.50 per m² |
| Grout cleaning and sealing | £6 to £14 per m² |
| Stone polishing and restoration | £20 to £60 per m² |
| Wood floor sanding and refinishing | £20 to £45 per m² |
Stone restoration and wood refinishing in particular are genuinely specialist, and a bad job is expensive to correct.
Frequently asked questions
Can I use a steam mop on any hard floor? Sealed tile, generally yes. Wood, laminate, vinyl, lino and most natural stone, no.
What is the best all-round hard floor cleaner? A pH-neutral cleaner, which is safe on almost everything including stone. Keep one bottle rather than five specialist ones.
Why does my floor look dull after mopping? Usually product residue or dirty water. Rinse with clean water and use less product.
How do I get grout white again? Alkaline grout cleaner and a stiff brush, then seal. If it is stained through, a grout pen or regrouting is the only real fix.
Is vinegar safe on floors? On sealed tile and vinyl, generally yes in dilution. On natural stone, absolutely not. On wood, it can dull the finish over time.
How often should hard floors be deep cleaned? Domestic, once or twice a year beyond routine mopping. Commercial, quarterly to annually depending on traffic.
