How to Properly Clean a Rosewood Fingerboard (Step-By-Step)
Guitar Space Team
Your guitar's fretboard (also known as a fingerboard) is so much more than a surface for pressing strings. It also influences playability, tone, and your guitar’s longevity. And neglecting its care can lead to issues like cracking, loose frets, and diminished value, especially if it’s made of rosewood.
Thankfully, learning how to clean a rosewood fretboard and provide regular maintenance is simple. In this article, we run through the simple steps to get the job done and give you a few recommendations for our favorite products.
Understanding Rosewood Fretboards
Ever wondered why most fretboards are made with rosewood? Thanks to its rich tone and natural oils, this material is a popular choice for stringed instruments. But its porous nature also makes it prone to issues.
What Impacts a Rosewood Fretboard?
This special material needs extra care because it naturally absorbs moisture and oils. This means your guitar's more likely to get grime buildup. And since rosewood is usually unfinished, it's exposed to environmental factors that make matters worse, including:
Humidity Levels: The ideal relative humidity for your guitar and its rosewood fretboard is between 40% and 60%.
Temperature Fluctuations: Extreme changes in your environment can cause the wood to expand or contract.
How to Identify a Dry Fretboard
Learning how to clean a rosewood fretboard is a must if you own a guitar. But first, you need to be able to tell if your fingerboard is dry or dirty. Here are a few telltale signs that it's ready for a clean:
Fading color: The wood looks lighter than usual.
Jagged Fret Edges: The fret wires feel sharp due to shrinking wood.
Visible Cracks: You can see small cracks or splits in the wood surface.
Tools and Materials Needed
Before you start cleaning and conditioning, gather your tools and materials. The process will be easier, and you'll do a more thorough job. Here's what you need:
Guitar String Winder: Optional but helpful for quick string removal.
0000-Grade Steel Wool: For cleaning frets and removing stubborn grime.
Soft Toothbrush: An effective alternative to steel wool for a gentle clean.
Clean, Lint-Free Cloths: For applying the oil and wiping the fretboard.
Painter's Tape: Protects the areas around the fretboard, especially on electric guitars.
Vacuum Cleaner: Used for removing debris after cleaning, but totally optional.
Alcohol Wipes or Swabs: For the first clean, when you're removing oils and dirt.
Recommended Products
High-Quality Lemon Oil: Choose a lemon oil specifically formulated for guitars. But most importantly, avoid using furniture-grade oils on your instrument. They can contain harmful additives that do more damage than good. Instead, look for these features:
Purity: Only use oils that are made for musical instruments.
No Additives: Avoid oils that include silicone or wax.
Brand Reputation: Be selective here. Choose products from reputable manufacturers that are renowned for good guitar care.

Preparing the Guitar
Remove the Strings. Carefully take off all strings to access the entire fretboard. For vintage guitars, take extra care. And if you're unsure, consider consulting a professional to avoid any damage while you restring.
Cleaning the Fretboard
Wipe it down. Gently clean the fretboard with alcohol wipes or swabs to remove any surface dirt and oils.
Protect Pickups. For electric guitars, cover the pickups with painter's tape. This prevents metal particles from steel wool from sticking due to magnetism.
Scrub gently. Using 0000-grade steel wool or a soft toothbrush, scrub the fretboard in circular motions with a little bit of pressure to lift stubborn grime.
Clean Up the Debris. Use a vacuum cleaner or a damp cloth to remove any leftover debris from the fretboard.
Let the Oil Soak: Allow the oil to sit for about one minute. Got an extremely dry fretboard? Let it soak for 10 to 15 minutes.
Wipe Away Excess Oil: Using a dry section of the cloth, rub the oil into the wood and wipe it clean until there’s no residue.
Optional Deep Conditioning
Second Oil Application: Severely dried-out fretboards? Apply a second layer of lemon oil and let it soak overnight.
Buff the Fretboard: The next day, buff the fretboard with a clean cloth and restore its shine.
Re-stringing the Guitar
Install New Strings: Using the right tension and alignment, you can carefully restring your guitar. Having new strings on your instrument will improve its sound and how it feels.
Maintenance and Prevention
After cleaning, you’ll need to stick to a regular maintenance schedule to keep your guitar conditioned and at its best. Follow these maintenance tips to preserve your rosewood fretboard and prevent any further issues.
Regular Cleaning Schedule
Frequency: Consider how often you play your guitar and adjust your schedule to suit. As a rule, you should clean your fretboard every few months or whenever you change strings. But some environments and guitars might need more.
Humidity Control
Maintain Proper Humidity: Keep your guitar in an environment with 40% to 60% relative humidity. A cheap hygrometer can help you keep an eye on it.
Use Humidifiers: Consider using guitar case or room humidifiers to keep optimal humidity levels.
Proper Storage: Always keep your guitar in its case when you're not playing it, and protect it from environmental fluctuations.
Bridge and Hardware Cleaning
Clean Regularly: Use a soft cloth every few weeks to wipe down the bridge and other metal and plastic hardware components. You'll prevent corrosion and grime buildup on your guitar.
String Care
Avoid Lemon Oil on Strings: Although effective on your fretboard, lemon oil can damage strings. Avoid contact with strings while you condition your fretboard.
Keep Strings Clean: Wipe down the strings after you play your guitar. You'll remove sweat and oils, and extend their lifespan.
Troubleshooting and Common Mistakes
Sometimes, your fretboards need a bit of extra TLC. And whether it’s your first or 50th time cleaning them, there are some things you should know. Be aware of these common pitfalls and avoid damaging your guitar while you condition and clean it.
Addressing Extremely Dry Fretboards
Reviving Dry Wood: Apply lemon oil and allow it to soak in longer, possibly overnight, to rehydrate the wood.
Avoiding Common Pitfalls
Wrong Oil Type: Using furniture-grade lemon oil is a no-no, as it contains harmful additives. Always use guitar-specific products.
Over-Oiling: Too much oil can lead to residue buildup. A little goes a long way.
Improper Use of Steel Wool: Using coarse steel wool or applying too much pressure can damage your fretboard and frets.
Vintage Instruments: Older guitars may require professional care to avoid damage during cleaning and restringing.
What to Do If You Have a Maple Fretboard
Different Care Requirements:Maple fretboards need a unique approach to cleaning, and you can't use steel wool on them. Check out specific guidelines for maple fretboards before you begin.
