How to Clean and Protect Hardwood Floors (Without Damaging Them)

Hardwood floors are one of the most valuable features in a Bay Area home — and one of the most commonly damaged by improper cleaning. Here's how to do it right.

What Damages Hardwood

• Excess water: hardwood swells, warps, and discolors when wet
• Vinegar: acidic and slowly strips the finish over time
• Steam mops: force moisture into wood seams
• Ammonia-based cleaners: dull the finish
• Oil soaps like Murphy's: leave residue that builds up

The most common hardwood mistake: too much water. A mop should be barely damp — wring it until almost dry before touching hardwood.

The Right Cleaning Approach

Daily/as needed: Sweep or dust mop to remove grit and debris. Grit acts like sandpaper on hardwood finishes when walked over.

Weekly: Damp mop only — use a flat microfiber mop, barely moistened. Use a pH-neutral hardwood floor cleaner (Bona is excellent).

Monthly: Check for any scuffs or dull areas. A small amount of hardwood floor polish can restore shine to dull spots.

For Spills

Wipe immediately with a clean dry cloth. Liquid on hardwood is a race against time — the longer it sits, the more damage it does.

Pet Owners with Hardwood

Keep pet nails trimmed. Use area rugs in high-traffic pet areas. Wipe pet food and water bowls underneath regularly — spillage is the #1 cause of hardwood damage in pet-owning homes.

When to Refinish

Bay Area hardwood typically needs refinishing every 7-10 years depending on traffic. Signs it's time: deep scratches that can't be buffed, dull areas that don't respond to cleaning, bare wood showing through the finish.
