Laminate is two floors in one board: a surface harder than any wood finish, which nothing in a normal house scratches, over a core of compressed wood fiber that swells the moment water reaches it. Cleaning laminate is entirely about keeping water off that core, which means the mop is the enemy and the vacuum is the friend.
The wear layer on laminate is aluminum oxide in melamine resin, and it is the most scratch-resistant floor surface sold for homes. It does not need a polish, a wax or a special product, and it does not scratch under a vacuum. What it cannot do is be refinished: when it is finally worn or damaged, the board is replaced.
Under it is high-density fiberboard, which is wood. Water that gets into a joint — from a wet mop, a steam mop, a spill left overnight — is absorbed by the core, which swells and does not shrink back. The raised, rough joint edges on an old laminate floor are that damage. The sealed-core tier is treated on every face and carries a waterproof warranty; the standard tier is the one this page is careful about, and the two look identical on the surface.
Cleaner residue. Wipe with a barely damp microfiber pad and clean water, dry with a towel, and use less product next time. Laminate rarely needs anything more.
That is not a cleaning problem and no product reverses it. The swollen board is replaced — the repair guide covers it — and the source of the water found.
Laminate warranties cover wear-through, fading and staining, and they exclude moisture damage in language that makes the point: most name steam mops, wet mopping and standing water specifically. A claim for a swollen joint is refused as water damage on a standard-core product every time. The sealed-core tier is the exception and its warranty says so in writing, sometimes naming a number of hours a spill can sit.
The same routine, deep and never lists the material pages carry, so the guide and the page cannot disagree.
It is tough. The joints between boards are not sealed, and the wood-fiber core behind them drinks. The damage from a bucket-and-mop routine shows up as raised joint edges across the whole room in a year or two, and nothing fixes it but replacement.
Steam-mop packaging says many things. Every laminate manufacturer excludes steam, because vapor enters the joints faster than liquid does. This is the most common way a laminate floor is destroyed in its first year.
Laminate cannot absorb a polish, so it sits on the surface as a streaky film that shows every footprint. The floor was at its correct sheen before the polish went on; getting back there means stripping it.
The sealed-core tier really is different. The standard tier from the same brand is not, and the boxes sit side by side. If the floor was installed by someone else, treat it as standard until the paperwork says otherwise.
The surface does not scratch easily, but when it does, there is no finish to buff. A color-matched repair pencil hides it; rubbing with anything abrasive makes a dull patch that is worse than the scratch.
Dry first: vacuum or dust-mop to get the grit up. Then a laminate cleaner sprayed lightly and wiped with a microfiber mop that feels almost dry. No bucket, no rinse water on the floor. That is the entire method, and doing less of it is safer than doing more.
No. Steam enters the joints as vapor and swells the fiberboard core from the inside; the joints peak and roughen and the damage is permanent. Every laminate manufacturer excludes steam cleaning from the warranty, and the sealed-core waterproof tier is not an exception.
Not with a wet mop. A damp mop wrung until it barely leaves a trace of moisture is fine; water that sits on the floor or runs into a joint is not. Sealed-core laminate with a written waterproof warranty tolerates a damp mop with less worry, but the habit is the same.
They shine when they are clean and dry, at whatever sheen they were made with. Haze is cleaner residue, removed with a barely damp pad and clean water. A polish adds a film that streaks; it does not add shine to a surface that cannot absorb it.
A cleaner labeled for laminate, which is a neutral, low-residue formula meant to be sprayed lightly and wiped off. Wood-floor cleaners are usually fine too. Not oil soap, not vinegar in quantity, not anything with polish or shine in the name, and not a bucket of anything.
No. The surface is a printed image under a resin wear layer, not a finish that can be sanded and recoated. A worn or damaged laminate board is replaced, which is why keeping a spare carton from the original order matters more for laminate than for any other floor.
