How to Care for Laminate Floors
How do I clean laminate flooring without ruining it, and why is standing water such a problem?
Laminate looks like wood but is built differently: a printed photographic layer under a tough melamine wear layer, all bonded to a high-density fiberboard (HDF) core. That wood-based core is the key to everything, because the single most important rule for laminate is keep standing water off it. The wear layer is very scratch- and stain-resistant, but water that reaches the core through seams or edges makes the fiberboard swell — and that swelling, seen as peaked or puffy plank edges, is permanent and cannot be sanded out.
Cared for correctly, laminate is one of the easiest and most durable surfaces to keep clean, and a damp mop and a broom are basically all it asks. The cost of neglect is unusually harsh, though: laminate can never be refinished, so a scratched, hazed, or water-swollen plank has to be replaced, not repaired. Prevention is the entire strategy.
Every Day
Routine Care
Sweep, dust-mop, or vacuum often
NALFA recommends regularly removing grit with a broom, dust mop, or vacuum on the bare-floor setting. Grit is abrasive and is what eventually dulls even a tough melamine wear layer in traffic lanes.
Damp-mop, never wet-mop
Use a well-wrung microfiber that leaves the floor barely moist and dry within a minute; NALFA and laminate makers call for a damp, not wet, mop. The goal is no standing water anywhere on the surface.
Wipe spills immediately
Blot spills the instant they happen so liquid never sits long enough to migrate into a seam. On laminate this isn't about stains — it's about protecting the fiberboard core from swelling.
Use a laminate-specific or pH-neutral cleaner
Apply an approved laminate cleaner by lightly misting the mop or floor, not flooding it. Avoid all-purpose cleaners that leave film or residue.
Trap grit and moisture at entries
Walk-off mats at every door catch the sand that scratches and the water and slush that threaten seams. This one habit prevents the two things most likely to ruin laminate.
Don't
What to Avoid on Laminate Floors
No wet mops, flooding, or standing water
Water that reaches the HDF core through seams causes irreversible edge swelling and peaking. This is the number-one killer of laminate floors and the reason wet-mopping is banned.
No steam mops
Steam forces hot moisture directly into the seams and core — exactly the damage laminate can't recover from — and it voids virtually every laminate warranty. Never steam-clean laminate, regardless of what the mop's box claims.
No wax, polish, oil soap, or shine products
Laminate is never waxed; these leave a dull, streaky film that can't be refinished off and traps dirt. NALFA advises against buffing, waxing, and polishing laminate.
No abrasive cleaners, scouring pads, or scrapers
Steel wool, scouring pads, and gritty powders scratch and cloud the wear layer permanently, and there's no sanding it back. Use soft cloths and mops only.
No strong vinegar, ammonia, or bleach
Harsh or acidic cleaners can dull the melamine surface and leave streaks over time. Stick to a laminate-approved or pH-neutral cleaner used sparingly.
Now & Then
Periodic Maintenance
Deep-clean lanes with a barely damp pass
A periodic damp clean with an approved laminate cleaner lifts built-up film in kitchens and hallways without waxing. Keep even this deep clean water-light.
Re-check perimeter and wet-area seals
In kitchens and baths, make sure any silicone or trim at the floor's perimeter and around the dishwasher is intact, since that's where water sneaks under laminate. Renew failing caulk before it lets moisture reach a seam.
Replace damaged or swollen planks
Because laminate can't be refinished, a scratched, hazed, or water-swollen plank is swapped out. Keeping spare planks from the original box makes color-matched repairs possible.
Prevention
Protect the Floor
- Put felt pads under all furniture legs and use wide, soft casters, since gouges in laminate can't be sanded out.
- Place absorbent mats at entries and in front of sinks and dishwashers — the spots where standing water most often threatens the core.
- Maintain reasonable indoor humidity and leave the manufacturer's expansion gap at the walls intact, so the wood-based core isn't forced to buckle when it moves with the seasons.
- In sun-drenched rooms, use blinds or UV-filtering film, since prolonged direct sunlight can fade the printed decor layer over years — especially on west- and south-facing windows.

Common Questions
Laminate Floors Care Questions
Everyone says laminate is durable, so why can't I mop it with water?
The surface is durable, but the core underneath is essentially compressed wood fiber, and it swells when water reaches it through the seams. That swelling shows up as permanently peaked or puffy plank edges that can't be sanded flat, so the plank has to be replaced. Laminate is tough against scratches and stains, but standing water is its true weakness. Always damp-mop, never wet-mop, and wipe spills right away.
What cleaner should I never use on laminate?
Skip oil soaps, waxes, and polish or shine products, which are the most common wrong choices. On laminate they leave a dull, streaky film that traps dirt and, because laminate can't be refinished, can't simply be sanded off. Also avoid abrasive powders and harsh acids. Use a laminate-specific or pH-neutral cleaner applied to a damp mop, and less is more.
Is laminate a good choice for Sacramento's dry, hot climate?
Yes, generally. Laminate isn't nearly as humidity-sensitive as solid wood, so our dry summers and heated winters cause far less seasonal movement, and it won't gap the way hardwood can. The bigger local watch-outs are strong sun on west- and south-facing rooms, which can fade the printed layer over years, and making sure water in kitchens and baths is wiped up fast. As long as the expansion gap at the walls was left intact at install, laminate handles our climate well.
Can a scratched laminate floor be refinished like wood?
No, and this is the key difference from real wood. Laminate has a photographic decor layer under a wear layer, with no solid wood to sand into, so it can't be sanded or refinished. Minor scratches can sometimes be disguised with a manufacturer's repair putty or filler pen, but a badly scratched, hazed, or swollen plank is replaced individually. That's why saving leftover planks from the original installation is so valuable.
