Hardwood floors are one of the most common investments homeowners make, and one of the most commonly damaged by well-meaning cleaning efforts. The irony is that most hardwood floor damage comes from cleaning, not from use. Too much water. The wrong products. Steam mops. Vinegar.
Getting this right isn’t complicated, but it’s specific. The best way to clean hardwood floors depends on what type of hardwood you have, what finish is on it, and what you’re trying to clean. This guide walks through all of it clearly, including what The Maids and similar competitors don’t cover: the specific challenges Minnesota’s climate creates for hardwood floor maintenance.
Know Your Floor Before You Clean It
Not all hardwood floors are the same, and cleaning the wrong type the wrong way causes permanent damage.
Solid hardwood: Real wood all the way through. Can be refinished multiple times. Sensitive to moisture and extreme humidity changes.
Engineered hardwood: A thin layer of real wood over plywood or composite. More stable in humid and dry conditions than solid hardwood. Cannot be refinished as many times.
Prefinished vs site-finished: Prefinished floors have the finish applied in the factory. Site-finished floors are finished after installation. Both need the same general care, but site-finished floors with older finishes may be more porous.
Waxed floors: Older hardwood floors (pre-1970s construction) are often waxed rather than polyurethane-finished. Most modern cleaning advice does not apply to waxed floors. Water, vinegar, and most commercial cleaners damage waxed floors. Use a wax-based cleaner only.
If you’re not sure what type of floor you have or what finish is on it, scratch a hidden area with a coin. If the finish flakes, it’s likely a surface finish (polyurethane). If it doesn’t flake, it may be penetrating oil or wax.
What NOT to Use on Hardwood Floors (The Most Important Section)
Steam mops: Never. The combination of heat and moisture penetrates the finish and the wood itself, causing swelling, warping, and finish damage that cannot be reversed. Steam mops are excellent for tile and other non-porous surfaces. They are permanently damaging to hardwood.
String mops: Traditional wet mops deposit too much moisture on hardwood floors. Excess water causes the wood to swell at the seams and can lead to cupping (edges of boards rising higher than the center). Use a flat microfiber mop that you can wring out almost completely.
White vinegar or other acids: Despite being widely recommended, vinegar and citrus-based cleaners are acidic and over time dull the polyurethane finish on hardwood floors. A single cleaning won’t cause obvious damage, but repeated use leaves a permanent haze that cannot be removed without refinishing.
Oil soaps (like Murphy’s Oil Soap): These products clean and temporarily add shine but leave a buildup over time that becomes a residue on the floor surface. This residue causes floors to look dull and creates problems when it’s time to refinish.
Ammonia-based cleaners: Ammonia strips the finish from hardwood floors and causes discoloration. Never use ammonia on wood.
Excessive water of any kind: Even a regular wet mop with too much water causes damage over time. Hardwood and water are adversaries.
What to Use on Hardwood Floors
A microfiber flat mop: This is non-negotiable. A flat microfiber mop that wrings out thoroughly is the correct tool for mopping hardwood floors. The microfiber captures dirt and debris without requiring much water.
pH-neutral hardwood floor cleaner: Products specifically formulated for hardwood floors, such as Bona Hardwood Floor Cleaner, are pH-neutral and won’t damage the finish. These are widely available at hardware and grocery stores. Dilute per the product instructions.
Dry microfiber mop or soft-bristled broom: For daily sweeping and dust removal. A Swiffer Sweeper or equivalent works well for daily maintenance.
Vacuum with a hardwood floor setting: A vacuum with the beater bar disabled and a hardwood floor attachment picks up debris from between boards without scratching the finish. Always check that the brush roll is off before vacuuming hardwood.
DIY hardwood cleaner (for light cleaning): Mix one tablespoon of dish soap in a gallon of warm water. This is mild enough for most polyurethane-finished floors. Do not use vinegar. The key is to barely dampen the mop, not to wet the floor.
How to Clean Hardwood Floors Step by Step
Step 1: Sweep or Dust Mop First
Always remove loose dirt, dust, and debris before any wet cleaning. Fine grit and debris pushed around by a wet mop acts as sandpaper on the floor finish.
Use a dry microfiber mop, a soft-bristled broom, or a vacuum with the beater bar off. Pay attention to the gaps between boards where debris accumulates, and get into the edges along baseboards.
In Minnesota homes during winter, the grit and sand tracked in from salted roads is particularly abrasive. Sweeping near entryways more frequently during winter months protects your floors.
Step 2: Spray and Mop in Sections
Spray your hardwood floor cleaner directly onto the floor in a small section, roughly 3×3 feet. Do not spray onto the mop head.
Mop with the grain of the wood. Working with the grain rather than across it reduces the visibility of any streaking and is less likely to force moisture into the seams between boards.
Work backward across the room so you’re never walking on the wet area you just cleaned.
The mop should be barely damp, not wet. If you wring it out and it still drips, it has too much moisture.
Step 3: No Rinsing Required
With a pH-neutral hardwood floor cleaner used at the correct dilution, no rinsing is necessary. The cleaner is designed to be used sparingly enough that residue isn’t left behind.
If the floor looks dull after cleaning, it’s likely from residue from previous cleaning products, not from the current cleaning. A light buffing with a dry microfiber cloth restores some shine.
Step 4: Allow to Air Dry
Hardwood floors cleaned correctly dry within minutes because the floor was barely damp to begin with. Don’t walk on the floor until it’s fully dry. Foot traffic on a damp wood floor leaves scuff marks.
How to Remove Stains From Hardwood Floors
Different stains require different approaches. Acting quickly on spills is the most important rule.
Water marks and rings: These typically appear as light white rings on the floor surface. Rub the mark with a small amount of paste wax or a dab of mayonnaise (yes, really). The oil penetrates and neutralizes the water mark. Leave for a few hours and buff with a soft cloth.
Wine and food stains: Blot up as much as possible immediately with a clean cloth. Do not rub. Apply a small amount of a hardwood floor cleaner to the area and let it dwell briefly. Wipe clean. For older stains, hydrogen peroxide on a clean white cloth placed over the stain for several hours can lighten it without damaging most polyurethane finishes.
Pet urine: This is one of the most damaging stains for hardwood floors because urine is highly acidic and penetrates the wood itself. Blot up what you can immediately. Apply a pet-specific enzymatic cleaner (not a general cleaner) and follow the product directions. Old or large pet urine stains may cause permanent discoloration that requires sanding and refinishing.
Scuff marks: Rub with a clean tennis ball or a clean sock balled up in your fist. The friction removes most surface scuffs. For harder scuffs, apply a small amount of baking soda on a damp cloth and rub gently.
Grease or oil: Apply a small amount of dish soap directly to the stain, let sit for two minutes, and wipe clean with a barely damp cloth.
Minnesota Winter and Hardwood Floors: Special Considerations
Minnesota homeowners face hardwood floor challenges that don’t apply in more temperate climates.
Salt and sand damage: Road salt and sand tracked in during Minnesota winters are abrasive to hardwood finishes. Place quality entry mats inside and outside every exterior door. Sweep or vacuum entryways daily during winter. The fine sand from salted roads is much more damaging to floor finishes than regular household dirt.
Humidity changes: Minnesota winters with forced-air heating dramatically reduce indoor humidity. Dry air causes hardwood to contract, which can create gaps between boards and occasionally cause cracking in extreme cases. The National Wood Flooring Association recommends maintaining indoor humidity between 35 and 55 percent for hardwood floor stability. A whole-home humidifier attached to the HVAC system is the most effective solution for Minnesota’s dry heating seasons.
Entry area floor protection: Consider area rugs in high-traffic areas near entry points during winter to protect hardwood from grit, moisture, and cold.
Spring cleaning floors: After a Minnesota winter, hardwood floors benefit from a more thorough clean to remove the salt residue and winter grime that accumulated. This is one of the most useful applications for a professional hardwood floor cleaning service.
How Often Should You Clean Hardwood Floors?
Daily or every few days: Dry sweep or dust mop to remove surface debris, especially in high-traffic areas. This is the most important maintenance step.
Weekly: Damp mop with a pH-neutral cleaner in heavily used areas like kitchens and living rooms.
Monthly: Full damp mop of all hardwood floors.
Seasonally: A deeper clean addressing any buildup from the season, especially post-winter in Minnesota.
Every three to five years: Professional refinishing to restore the finish to the floor. Well-maintained floors need less frequent refinishing.
Hardwood Floor Maintenance: Preventing Damage
Use furniture pads on all chair and furniture legs. The small discs of felt or cork that attach to furniture legs prevent scratching when furniture is moved or shifted. This is one of the most effective and inexpensive protections for hardwood floors.
No shoes inside. The grit and debris on shoe soles scratches floor finish continuously. Hardwood floors in homes with a no-shoes policy last significantly longer between refinishing.
Trim pet nails regularly. Pet nails on hardwood floors cause scratches that, over time, dull the finish in high-traffic pet areas.
Clean up spills immediately. Spills left on hardwood floors cause water damage, staining, and in the case of acidic liquids (wine, juice, coffee), finish damage.
Never drag furniture across hardwood floors. Always lift and carry, or use furniture sliders.

Frequently Asked Questions
What is the best thing to use to clean hardwood floors?
A pH-neutral hardwood floor cleaner (like Bona) applied with a barely damp flat microfiber mop is the best approach for finished hardwood floors. Avoid vinegar, oil soaps, steam mops, and excessive water.
Can you use a Swiffer WetJet on hardwood floors?
The Swiffer WetJet itself is designed for hard floors, but the cleaning solution uses is not recommended by many hardwood floor manufacturers. Use the Swiffer Sweeper for dry cleaning of hardwood, or refill the WetJet with a pH-neutral hardwood cleaner rather than the standard pads.
How often should hardwood floors be mopped?
Dry sweeping daily or every few days in high-traffic areas, damp mopping weekly in used areas, and a full damp mop monthly for all hardwood floors.
Does vinegar damage hardwood floors?
Yes, over time. A single cleaning with diluted vinegar won’t cause obvious immediate damage, but the acidic pH of vinegar dulls the polyurethane finish with repeated use. This creates a permanent haze that can only be removed by refinishing.
Can you use a steam mop on hardwood floors?
No. Heat and moisture from steam mops cause swelling, warping, and permanent finish damage to hardwood floors. This is one of the most common causes of hardwood floor damage from cleaning.
How do you clean hardwood floors in winter in Minnesota?
During winter, sweep or vacuum entryways daily to remove road salt and grit before it scratches the floor. Use quality entry mats inside and outside all exterior doors. Maintain indoor humidity between 35 and 55 percent to prevent board gaps from dry heating air.
How do you remove scuff marks from hardwood floors?
Rub with a clean tennis ball or balled-up clean sock. The friction removes most surface scuffs without chemicals. For more stubborn scuffs, a small amount of baking soda on a damp cloth, rubbed gently, removes most marks without damaging the finish.
