How to Clean Polished Timber Floors

Without damaging the finish.

To protect your investment after professional floor sanding Brisbane homeowners should know the right way to clean polished timber floors is simple: remove grit with a soft broom or a vacuum with the beater bar off, then mop with a barely damp microfibre mop and a pH-neutral timber floor cleaner. That is the whole routine. Most damage to polished floors comes not from dirt but from the cleaning itself: steam mops, wet mopping, vinegar, oil soaps and abrasive pads all attack the coating that protects the timber. This guide covers the routine, what to avoid, how to protect your Floor Polishing Brisbane finish, and how to tell when cleaning is no longer enough.

How often should a polished timber floor be cleaned?

• Every day or two: sweep or vacuum. Grit is the enemy. Sand and small stones act like sandpaper under shoes and chair legs, and most fine scratching on a floor is grit being ground into the coating.
• Weekly, or as needed: damp mop with a microfibre mop and a pH-neutral cleaner made for polyurethane-coated timber floors.
• Immediately: wipe up spills, and especially pet urine. Liquid that sits on a coating finds its way through.

What should you never use on a polished timber floor?

• Steam mops. Heat and pressurised moisture force water into the joints and under the coating, and can cloud or lift the finish. Manufacturers of timber floor coatings do not warrant steam-cleaned floors.
• Wet mopping or hosing. Standing water swells the boards, opens gaps and causes cupping. The mop should be damp, never wet, and the floor should dry within a minute or two.
• Vinegar and other acidic cleaners. Vinegar dulls polyurethane over time. It does not disinfect a floor and it does not make it shine.
• Oil soaps, wax and silicone-based polishes. These leave a film that builds up, attracts dirt, looks patchy and stops any future recoat from bonding. A floor that has been waxed or treated with silicone polish may need a full sand before it can be recoated.
• Abrasive pads, scourers and stiff brushes. They scratch the coating.
• Ammonia, bleach and all-purpose sprays. Too harsh for the finish and unnecessary.

How do you protect the finish between cleans?

• Mats at every external door catch most grit before it reaches the floor.
• Felt pads under every chair and table leg, checked and replaced when they wear through or pick up grit.
• Lift furniture rather than drag it.
• Keep pet claws trimmed and wipe up accidents at once. Urine that sits on the coating penetrates and stains the timber black, which no cleaner can remove.
• Check under rugs regularly. Rugs hide spills and hold moisture against the coating, and the worst pet stains are found under them.
• Use rugs with breathable, non-staining backings. Rubber and latex backings can react with polyurethane and leave a permanent mark.
• Manage sunlight. Timber changes colour under strong sun, and a rug left in one spot for years leaves a lighter patch when it is moved. Blinds, sheer curtains and moving rugs occasionally even it out.

What causes dull patches and footprints that will not clean off?

If a section of floor stays dull however you clean it, or shows footprints that reappear after every mop, the problem is in or under the coating, not on it. Dull traffic lanes are worn coating. Footprints that will not clean off are usually ghosting, a defect in the coating that only full sanding removes. More cleaning, or a stronger product, makes neither better.

When is cleaning no longer enough?

A polished floor has two layers: the coating and the timber. Cleaning looks after the coating while it is intact. Once the coating is worn or damaged, the floor needs one of two things:

• A recoat, if the wear is confined to the coating: dull lanes, fine scratches, a tired overall look. With a UV-cured coating the floor can be recoated and back in use the same day.
• A full sand and new coating system, if the damage has reached the timber: deep scratches, black stains, water damage, ghosting, or a floor that has been waxed or oiled. There is no such thing as a light sanding that fixes these.

Recoating a floor before it wears through to bare timber is the cheapest maintenance there is, because it avoids the next full sand.

Frequently asked questions

Can I use a steam mop on polished floorboards?

No. Steam forces moisture into the timber and under the coating and can cloud or lift the finish. Use a barely damp microfibre mop instead.

Is vinegar and water safe for polished timber floors?

No. Vinegar is acidic and dulls polyurethane over time. Use a pH-neutral cleaner made for coated timber floors.

How do I make my polished floor shine again?

Do not use a polish, wax or shine product; they build up and cause problems later. If a properly cleaned floor still looks dull, the coating is worn and the floor needs a recoat.

How do I remove scuff marks?

Most rubber scuffs lift with a damp microfibre cloth and a little pH-neutral cleaner. Do not use abrasive pads or solvents on the coating.

How long does a polished timber floor last before it needs sanding?

It depends on the coating system, traffic and care. A harder coating such as UV-cured polyurethane, kept free of grit and recoated before it wears through, goes many years between full sands.
