What cleaning products should I avoid on hardwood floors in NB?

Avoid vinegar, ammonia, steam mops, oil soap, and all-purpose household cleaners on hardwood floors — these are the most common products that NB homeowners use thinking they are helping, when they are actually degrading the finish and damaging the wood over time.

Vinegar and water is perhaps the most widely recommended "natural" hardwood cleaner, and it is one of the worst. Vinegar is acetic acid — diluted, but still acidic enough to etch polyurethane finishes with repeated use. Over months of vinegar-and-water mopping, the finish becomes dull, hazy, and prematurely worn. This is especially damaging in NB homes where the finish is already under stress from seasonal humidity swings causing micro-flexing and cracking.

Ammonia-based cleaners (including many glass cleaners like Windex) are even more aggressive. Ammonia strips the finish, discolours the wood, and leaves a sticky residue that attracts dirt. Never use any product containing ammonia on hardwood.

Murphy's Oil Soap and similar oil-based wood cleaners are problematic for a different reason. They leave an oily residue that builds up on the finish surface over time, creating a dull, smeared appearance. This residue also interferes with future refinishing — a professional refinisher will need to strip the oil buildup before applying new finish, which adds time and cost. If your floors have been cleaned with oil soap for years, a professional screening may be needed to remove the accumulated residue.

All-purpose household cleaners (Mr. Clean, Pine-Sol, Lysol floor cleaners) are formulated for tile, vinyl, and linoleum — not hardwood. They contain surfactants and chemicals that can dull polyurethane, leave residue, and strip wax finishes. The "for all floors" label on these products is misleading.

Steam mops force hot moisture into the seams and finish of hardwood floors. In New Brunswick, where seasonal humidity changes already stress wood dimensionally, adding concentrated steam to the equation accelerates finish failure, can cause localized swelling at plank edges, and pushes moisture into joints where it promotes rot in older NB homes with softwood subfloors.

What to Use Instead

The best cleaning routine for hardwood floors in NB is simple: dry dust mop daily (or every few days) to pick up grit and debris — this is especially critical during NB winters when tracked-in road salt and sand act as abrasives under foot traffic. For wet cleaning, use a manufacturer-recommended hardwood floor cleaner like Bona Hardwood Floor Cleaner, Harwood Floor Cleaner by Basic Coatings, or the product recommended by your specific floor's manufacturer. Apply sparingly with a damp (not wet) microfibre mop — the mop should feel barely moist to the touch. Never pour cleaning solution directly on the floor, and never leave standing water.

During NB's spring season when tracked-in mud and salt residue are heaviest, increase your dry mopping frequency to daily. A quick pass with a microfibre dust mop takes 5 minutes and prevents grit from grinding into the finish under foot traffic.

Keeping your cleaning routine simple and avoiding harsh chemicals will extend the life of your hardwood finish by years — saving you the $3,000-$6,000 cost of a full refinish on a typical NB main floor.
