What Is Murphy’s Oil Soap?
Murphy’s Oil Soap is a natural wood cleaner that has been around for more than 100 years. The main ingredients include vegetable oil soap (derived from plants), water, and a small amount of fragrance. Unlike harsh chemical cleaners, this soap is gentle and does not strip away the natural oils that protect hardwood floors.
Many people choose Murphy’s Oil Soap because it is:
- Biodegradable and environmentally friendly
- Safe for most finished wood surfaces
- Trusted by cleaning professionals and homeowners alike
It’s important to know that Murphy’s Oil Soap is designed for *finished* wood, not raw or unfinished floors. The finish acts as a barrier, so the soap cleans without soaking into the wood.
Why Choose Murphy’s Oil Soap For Hardwood Floors?
Hardwood floors are both beautiful and valuable, but they need careful cleaning to avoid scratches, warping, or dullness. Many regular cleaners are too strong or leave a sticky residue. Murphy’s Oil Soap stands out for several reasons:
- Gentle formula: It cleans without stripping the protective finish.
- No wax or silicone: These can build up and make floors slippery or cloudy.
- Natural scent: Many users prefer its fresh, not overpowering smell.
- Affordable and easy to find: Available in most supermarkets and hardware stores.
Most importantly, it’s a cleaner that does not require rinsing, as long as you use it correctly. However, it’s always wise to test it on a small area first, especially if your floor has an unusual finish.

Preparing Your Hardwood Floors For Cleaning
Before you use Murphy’s Oil Soap, your floors need a little preparation. This ensures you remove dirt and dust that could scratch the wood during washing.
Step 1: Clear The Area
Remove rugs, chairs, and any small furniture. This gives you full access to the floor and prevents dirt from hiding under objects.
Step 2: Sweep Or Vacuum
Use a soft-bristle broom or a vacuum with a hardwood floor setting. Avoid beater bars or stiff brushes, as these can scratch the finish.
- Sweep slowly, paying attention to corners and under baseboards.
- If vacuuming, use the bare floor attachment, not a rotating brush.
Step 3: Check For Sticky Spots
If you see dried spills or sticky areas, gently wipe them with a damp cloth. Do not use harsh scrubbers or excessive water.
Step 4: Inspect The Floor Finish
Murphy’s Oil Soap is safe for sealed (finished) wood. If you’re unsure, test a few drops of water in an out-of-sight spot. If the water beads up, the finish is good. If it soaks in, your floor may be unsealed and should not be cleaned with liquid soap.
How To Mix Murphy’s Oil Soap Properly
Getting the right mix is important for effective cleaning. Using too much soap can leave a film; too little may not clean well.
Standard Mixing Instructions
- For regular cleaning, mix 1/4 cup of Murphy’s Oil Soap with 1 gallon of warm water.
- For heavier cleaning, you can use up to 1/2 cup per gallon. Avoid using it full-strength on floors.
A common mistake is to pour the soap directly on the floor or use too much product, which can make floors sticky.
| Cleaning Need | Murphy’s Oil Soap | Water |
|---|---|---|
| Light cleaning | 1/4 cup | 1 gallon |
| Heavy cleaning | 1/2 cup | 1 gallon |
| Spot cleaning | Few drops on cloth | Damp cloth only |
Always mix the solution in a clean bucket. Stir gently to avoid bubbles.
Step-by-step Guide: Cleaning Hardwood Floors With Murphy’s Oil Soap
Now you’re ready to clean. Follow these steps carefully for the best results.
Step 1: Choose The Right Mop
A soft mop is best. Microfiber mops or cotton string mops work well. Avoid sponge mops or anything abrasive.
Step 2: Dip And Wring
Dip your mop into the soap solution. Wring it out well so it’s damp, not wet. Too much water is bad for wood floors and can cause warping.
Step 3: Mop In Sections
Work in small sections, about 3×3 feet at a time.
- Mop following the grain of the wood.
- Rinse the mop often in the bucket.
- Wring out excess water each time.
Step 4: Dry As You Go
After mopping each section, dry it with a clean towel or microfiber cloth. This prevents water spots or streaks and protects the wood.
Step 5: Change The Solution If Needed
If your water gets dirty, empty the bucket and make a fresh batch of cleaning solution. Dirty water can leave residue behind.
Step 6: Let The Floor Air Dry
Once finished, let the floor air dry for 10-15 minutes. Keep pets and children off the floor until it’s completely dry.
Extra Tips For Shiny, Streak-free Floors
Murphy’s Oil Soap is gentle, but technique matters just as much as the cleaner. Here are some tips to make your floors shine:
- Use clean water and a clean mop every time.
- Don’t use hot water; warm is best.
- Avoid over-wetting the floor.
- Mop in the direction of the wood grain for a more even finish.
- Open windows or use fans to speed up drying.
A non-obvious tip: If you notice cloudy spots after cleaning, it may be leftover soap. Buff the area with a dry microfiber cloth to restore shine.
Common Mistakes To Avoid
Many beginners make simple mistakes that can leave floors dull or even cause damage. Here’s what to watch out for:
- Too much soap: More soap does not mean cleaner floors. It can leave a sticky film.
- Too much water: Wood and water don’t mix. Always wring out your mop well.
- Skipping dust removal: Dirt and grit can scratch the surface during mopping.
- Using the wrong mop: Hard or abrasive materials can damage the finish.
- Not drying the floor: Even a little standing water can cause wood to swell or stain.
A practical example: If you see footprints on your dried floor, it usually means you used too much soap or didn’t change the water often enough.
Spot Cleaning: Dealing With Stains And Sticky Messes
Murphy’s Oil Soap is not just for regular cleaning. You can also use it for small spots and tough messes.
For Sticky Spills
- Apply a few drops of Murphy’s Oil Soap to a damp cloth.
- Gently rub the spot.
- Wipe with a clean, damp cloth to remove any residue.
- Dry immediately with a towel.
For Scuff Marks
- Rub gently with a cloth dampened with the cleaning solution.
- Do not scrub hard—let the soap do the work.
- Buff dry.
For Old Or Stubborn Stains
- Mix a slightly stronger solution (1/2 cup per gallon).
- Use a soft-bristle brush and gently work on the spot.
- Wipe away with a clean, damp cloth and dry.
Avoid using steel wool, harsh chemicals, or vinegar, as these can damage the finish.

How Often Should You Clean Hardwood Floors With Murphy’s Oil Soap?
Frequency depends on your home’s traffic, pets, and lifestyle. In most homes:
- Weekly: Light cleaning with Murphy’s Oil Soap keeps dust and dirt under control.
- Every 2-4 weeks: Deeper cleaning for high-traffic areas.
- Immediately: Spot clean spills as soon as they happen.
Over-cleaning can wear down the finish, so don’t mop more than needed. Sweeping or dry mopping daily helps reduce the need for wet cleaning.
Comparing Murphy’s Oil Soap To Other Hardwood Floor Cleaners
You may wonder how Murphy’s Oil Soap stacks up against other products. Here’s a comparison of common hardwood floor cleaners:
| Cleaner | Main Ingredient | Residue Risk | Safe for Pets/Kids | Cost (per use) |
|---|---|---|---|---|
| Murphy’s Oil Soap | Vegetable oil soap | Low (if diluted) | Yes | Low |
| Vinegar & Water | Acidic vinegar | Medium (can dull finish) | Yes | Very low |
| Commercial Spray | Various chemicals | Medium-High | Check label | Medium |
| Wax-based Cleaner | Wax, solvents | High (build-up risk) | No (slippery) | High |
Murphy’s Oil Soap is one of the safest, especially if you avoid overuse. It does not contain harsh chemicals or acids that can harm modern floor finishes.
When Not To Use Murphy’s Oil Soap
Murphy’s Oil Soap is not suitable for every floor or situation. Here’s when to avoid it:
- Unsealed wood floors: These floors absorb water, leading to swelling and damage.
- Waxed floors: The soap can strip away wax and leave uneven spots.
- Laminate or engineered floors: Check the manufacturer’s instructions. Some laminates are sensitive to moisture.
- Oiled or unfinished wood: The soap is meant for sealed finishes only.
If you’re unsure, test the product in a small, hidden area first.
Caring For Your Hardwood Floors After Cleaning
Cleaning is just one part of caring for hardwood floors. Here are ways to keep your floors beautiful between cleanings:
- Place mats at doors to catch grit and moisture.
- Use felt pads under furniture to avoid scratches.
- Keep pet nails trimmed to prevent marks.
- Control humidity in your home to prevent wood movement.
- Avoid walking on floors with high heels or sports cleats.
A non-obvious tip: Rotate rugs and furniture occasionally to prevent uneven fading from sunlight.
The Long-term Impact Of Regular Cleaning
Regular care with Murphy’s Oil Soap extends the life of your hardwood floors. Consistent cleaning:
- Prevents buildup of dirt and grime that can scratch the finish
- Maintains the natural shine without the need for harsh chemicals
- Reduces allergens like dust and pet hair
A well-maintained floor can last for generations, protecting your home’s value. In fact, studies show that well-cared-for hardwood floors can increase a home’s resale value by up to 2. 5% compared to homes with carpet or damaged wood.
Environmental And Health Considerations
Murphy’s Oil Soap is popular with eco-conscious families because it’s biodegradable and contains no harsh chemicals. It is safe for most homes, including those with children and pets, when used as directed.
However, always store cleaning products out of reach of children. If you have allergies or sensitivities, check the ingredient list for plant oils or fragrances.
