How to Clean an Acoustic Guitar

Published Categorized as Care and Maintenance

The rich, melodic tones of an acoustic guitar have a unique ability to resonate with listeners and evoke deep emotions. But like any treasured possession, the acoustic guitar requires regular care to maintain its glow and sound quality. Everyday playing can lead to a build-up of dirt, sweat, and oils, which can diminish its sonic clarity and visual appeal. Cleaning your acoustic guitar is more than aesthetics; preserving its integrity and ensuring every strum and note is as intended. Dive into this guide to discover the art of cleaning and caring for your acoustic gem.

Why Clean Your Guitar?

Dirt and grime on a guitar might seem harmless at first. They subtly accumulate over time, primarily if the guitar is frequently used or stored in an environment exposed to dust particles. But this seemingly innocent layer of dust can affect your guitar’s sound quality.

The strings of the guitar are the primary source of its sound. When grime settles on the strings, it can cause sound distortion. The dirt can dampen the strings’ vibration, making them dull or out of tune. Rust can also form on metallic strings if not cleaned for extended periods, further distorting the sound and weakening the strings, making them prone to snapping.

The guitar’s wood, especially on the fretboard and body, is equally essential for sound production. Dust particles can infiltrate the tiny pores of the guitar wood, affecting its ability to resonate sound effectively. Over time, the accumulated dirt can cause the wood to lose its luster and damage the finish. The wood can become dry and brittle, impacting the guitar’s lifespan.

So the next time you see a little dirt on your fretboard or feel a grime-covered string under your fingers, remember the long-term effects of dirt on the guitar and make cleaning a regular part of your guitar care routine.

List of Cleaning Methods

How you maintain your acoustic guitar can profoundly influence its sound quality, appearance, and lifespan. Let’s explore some standard acoustic guitar cleaning methods and explore the best ways to keep your guitar in pristine condition.

Method 1: Preventive Cleaning

Preventive cleaning is the cornerstone of guitar care. Maintaining a proactive guitar cleaning regimen ensures that dirt, grime, and sweat don’t accumulate on your instrument. This method involves simple steps after each play—like wiping the strings and the body—to forestall the need for intense cleaning sessions in the future. Remember, preventing guitar dirt buildup is easier than remedying it.

Method 2: Wipe Down Cleaning

Arguably the most straightforward method on our list, a wipe-down cleaning entails using a clean, soft cloth to remove any immediate residue from your guitar’s surface. It’s a quick guitar maintenance technique that can be performed after every play session. This approach not only maintains the glow of the guitar but also prevents sweat and oils from your fingers from corroding the strings. When in doubt or short on time, always go for a good wipe-down.

Method 3: Deep Cleaning

Over time, even with regular maintenance, guitars may require a more thorough cleaning, especially if they’ve been exposed to various environmental factors. Deep cleaning goes beyond surface care and addresses the grime that settles into the nooks and crannies of the guitar. Using specialized cleaners and tools, this method ensures that every part of your instrument, from the strings to the fretboard, is spotless. If your guitar sounds a bit off or looks visibly dirty, it might be time for a deep clean.

Method 4: Outsourcing guitar cleaning to experts

For those who are still deciding whether to clean their acoustic guitar or have a vintage or particularly valuable guitar, professional cleaning services are the way to go. Guitar cleaning experts use specialized tools and have extensive knowledge about different guitar materials and how to care for them. They can provide thoroughness and attention to detail that can be challenging to achieve at home. Consider this option if you want the best care for your guitar, especially if it’s a significant investment or holds sentimental value.

Method 5: Quick Spot Cleaning

Spills happen. Maybe you enjoyed a beverage while practicing, and a few droplets landed on your guitar. Quick spot cleaning immediately addresses these minor stains before they set in. You can remove these spots with a damp cloth and a tiny amount of mild cleaner before they become a more significant issue. Always have your cleaning essentials nearby; rapid guitar stain removal can save you a lot of trouble in the long run.

Gathering the Right Tools

Just like a painter needs the right brushes or a chef needs suitable knives, you need the right tools when cleaning an acoustic guitar. The appropriate cleaning materials can make a world of difference in the result. Here’s a list of essentials for your acoustic guitar cleaning kit.

  • Soft Cloth: Every guitarist should have a soft, lint-free cloth in their guitar care kit. This cloth is perfect for wiping down the guitar body, neck, and strings after each play session. It helps remove sweat, oils, and dust, preventing them from building up over time. Microfiber cloths are popular, as they are gentle on the guitar’s finish and highly effective in trapping dirt.
  • Guitar Polish: While using regular furniture polish is tempting, a specialized guitar polish is recommended for your acoustic guitar. This polish is designed to be gentle on the guitar’s finish while effectively cleaning and adding a protective layer. It helps maintain the luster of the guitar’s body and extends its lifespan by preventing moisture and dirt buildup.
  • String Cleaner: The strings are the heartbeat of any guitar. Over time, they can accumulate grime and corrode due to sweat and oils from our fingers. A dedicated string cleaner can help maintain the brilliance of the strings and prolong their life. Using it regularly can make the strings feel smoother and sound brighter.
  • Cleaning Materials: Beyond the basics, other cleaning essentials can come in handy. These might include a small brush to clean tight spots like the bridge or tuning pegs, a fretboard conditioner for the fingerboard, and a humidifier to ensure the wood doesn’t dry out if you’re in an arid climate.
  • Guitar Care Kit: Many brands offer guitar care kits for those who want an all-in-one solution. These kits often contain various products, from polishes and cleaners to cloths and brushes. They’re convenient, ensuring you have everything you need in one place, and often come with instructions, making the cleaning process straightforward.

Equipping yourself with the right guitar cleaning tools is half the battle. Not only do they make the cleaning process more manageable, but they also ensure that your acoustic guitar remains in the best possible condition, ready to serenade audiences for years to come.

Preparation

Before diving into the intricate process of cleaning your acoustic guitar, adequate preparation is vital. Just as an artist sets up their canvas before painting or a chef gathers their ingredients before cooking, taking the necessary pre-cleaning steps ensures that your guitar cleaning session is both practical and safe. Here’s how to adeptly prepare your guitar for the cleaning process:

Choose a Safe Workspace

Select a flat, stable surface to work on, ideally covered with a soft cloth or towel to prevent scratches. Ensure that the workspace is well-lit to spot any dirt, grime, or blemishes on your guitar easily. Keep all your cleaning tools within arm’s reach to maintain a seamless workflow.

Loosen or Remove Strings

For a thorough cleaning, especially if you want to clean the fretboard or apply conditioner, consider loosening or completely removing the strings. Loosened strings provide easier access to the guitar’s surface, while complete removal offers an unhindered cleaning experience. If the strings are old and you were planning to replace them, this is the perfect time.

Inspect the Guitar

Before applying any cleaning solutions or tools, inspect your guitar thoroughly. Look for any signs of damage, cracks, or dents. This step ensures you’re aware of any fragile areas and can treat them with extra care during the cleaning process.

Gather Cleaning Supplies

Having previously established the importance of using specific guitar cleaning tools, now’s the time to gather all your essentials. From the soft cloth to string cleaner and guitar polish, having everything at your fingertips ensures a smooth cleaning process.

Disassemble If Needed

For those keen on a comprehensive cleaning session, consider removing components like the tuning pegs or bridge pins. This is optional for basic cleaning, but for deep cleaning sessions, disassembly provides better access. If you’re not comfortable with the disassembly, it’s always best to consult with a professional or refer to guides specific to your guitar model.

Cleaning the Guitar Body

The body of the guitar is its most substantial and noticeable part. Being the primary resonating chamber, it plays a critical role in sound production and is the first thing people notice about your instrument. Here is how to ensure your guitar’s body remains pristine and radiant:

  • Dust Off. Begin by gently dusting off the guitar body with a soft, lint-free cloth to remove any loose particles. This prevents any scratching or scuffing during the subsequent cleaning steps.
  • Apply the Polish. Opt for a guitar-specific polish or cleaner. Avoid household cleaners or general-purpose polishes, as they can damage the guitar’s finish. Pour a small amount onto a cloth — less is more. You can always add more if needed.
  • Clean the Front. Start with the front or the top of the guitar. Gently apply the polish using the cloth in a circular motion. Ensure you’re working on small sections at a time to prevent the polish from drying out prematurely. Be extra cautious around the bridge and soundhole. Removing smudges and fingerprints will help preserve the wood’s shine and enhance the overall aesthetics.
  • Clean the Back and Sides. After the front, move on to the back of the guitar and then the sides. Use the same circular motion technique, ensuring you cover every inch. The back and sides might have fewer embellishments than the front, but giving them the same care will ensure uniformity in shine and protection.
  • Remove any Excess Polish. Once you’ve covered the entire body, take a fresh cloth and gently buff the surface to remove any excess polish. This step ensures an even shine and helps reveal any spots you might have missed during the initial cleaning.
  • Inspect and Touch-up. Hold the guitar against a light source and inspect for missed patches, streaks, or residues. Address these areas with a quick touch-up using the cloth and polish.
  • Air Dry. Let the guitar sit briefly in a safe spot, allowing the polish to settle and any remaining moisture to evaporate.

Cleaning the Fretboard

The fretboard, often known as the fingerboard, is one of the most vital components of your guitar. This is where your fingers press down on the strings to produce different notes. Due to constant contact with fingers, the fretboard tends to accumulate oils, dirt, and grime. Cleaning and maintaining it ensures optimal playability and preserves its look and feel. Here are the basic steps in cleaning the fretboard of your guitar:

  • Start with the Strings. To access the entire fretboard easily, either loosen the guitar strings or remove them entirely. If they’re old or show signs of wear, consider replacing them after the cleaning process.
  • Dust the Surface. Begin by gently brushing away any loose dirt or debris using a soft brush or cloth. Ensure you get into the spaces between the frets, as that’s where most of the grime tends to accumulate.
  • Clean the Frets. For the metal frets, use a fine steel wool pad (grade #0000) to rub them gently. This will remove any oxidation and restore their shine. Remember to move toward the wood grain to avoid any potential scratches.
  • Clean Between the Frets. Gently scrub the wood between the frets using a damp cloth with mild soap. Be cautious and ensure the fabric isn’t overly wet – you don’t want to introduce excess moisture to the wood.
  • Condition the Fretboard. After cleaning, the wood can sometimes become dry. A fretboard conditioner, like lemon oil, can be beneficial. Apply a small amount to a cloth and rub it into the wood. This moisturizes the fretboard and prevents it from drying out and cracking. Ensure the oil you use is suitable for your fretboard. Some woods, like maple, take poorly to certain oils.
  • Wipe Away Excess. After conditioning, use a clean cloth to remove excess oil or conditioner to prevent residue or a sticky feel.
  • Restringing. Once the fretboard is clean and dry, it’s time to restring your guitar. If you’re using new strings, this is an excellent opportunity to tune and test them.

Cleaning the Hardware

The process of cleaning the hardware of your acoustic guitar is similar to all other parts. Start with a soft brush (an old toothbrush works well) to gently remove accumulated dust or grime on the tuner pegs and mechanisms. Then, gently rub the tuners’ surface with a small amount of chrome or metal polish to a soft cloth. This not only cleans but also gives a shine to the metal parts. If the tuners feel stiff or gritty, a drop of lubricant on the gears can help smoothen their operation.

The next part is cleaning the Bridge and Tailpiece. Use your soft brush to remove dirt from the bridge and tailpiece. Like with the tuners, use metal polish and a soft cloth for these parts. Ensure you reach all the nooks and crannies. After cleaning, ensure all moving parts, like adjustable saddles, function correctly.

Check the remaining hardware components, such as the strap buttons, input jack, or pickguard screws. These can also accumulate grime, so clean them similarly with a cloth and metal polish.

Reassembly or Restring the Guitar

After an intensive cleaning session, reassembling or restringing your guitar can feel like piecing together a cherished jigsaw puzzle. The goal remains the same: ensuring each part fits seamlessly, allowing the instrument to sing harmoniously once more.

When we speak of guitar reassembly, it implies putting back any components that might have been removed during the cleaning process, such as the bridge pins, saddle, or even tuners in some instances. Begin by ensuring the guitar’s body is free from any cleaning residue. If you have removed the saddle, place it back in its groove, ensuring its flat side faces the neck.
Should your guitar come with a removable nut, it is time to fix it back into position, paying attention to its orientation.

The process of restringing demands precision and patience. The idea is to breathe fresh life into your guitar, rejuvenating its sound. If you’re replacing old strings, remove them first. Unwind each string using a string winder until slack, then unhook from the tuning peg. Gently pull out the bridge pin, releasing the string from the bridge.

Starting with the low E string (or 6th string), thread the string through its corresponding hole in the bridge. As you insert the bridge pin, ensure the string’s ball end is seated against the bridge plate inside the guitar and not resting on the pin’s end.

Then, pull the string towards the headstock and thread it through the hole in its respective tuning peg. Aim for roughly 2-3 inches of slack before tightening.

The next step is to wind and tune your guitar. Begin winding the string, ensuring the windings are neatly stacked below the hole in the tuning peg. This provides a better angle over the nut, enhancing sound and playability. Once secured, tune the string roughly to pitch, knowing it’ll need fine-tuning later.

Utilize the same methodology for each string, working your way to the high E string (or 1st string).
After restringing, gently stretch each string by holding it and lifting it slightly, then re-tuning. This process helps settle the strings, ensuring they maintain their tune better.

Lastly, post-restringing, take a moment to inspect the guitar. Ensure the bridge pins are seated well, the strings sit comfortably in the nut slots, and there are no unusual gaps or overlaps in the tuning peg windings.

When Do You Need to Do a Deep Clean?

While regular cleaning keeps most dust and dirt at bay, there are moments when your guitar beckons for a thorough, deep cleaning. But how do you recognize these moments? Here are some of the most common signs that signal it’s time to roll up your sleeves and give your guitar the deep cleanse it deserves.

Dull Resonance and Sound Quality

One of the most immediate indicators that your guitar needs deep cleaning is a noticeable dip in its sound quality. Over time, dust and dirt can build up in the tiny crevices of your guitar, muting its resonance and altering its tone. If your acoustic guitar doesn’t sound as vibrant or resonant as it once did, it may be shouting for a deep clean.

Visible Dirt and Grime Build-Up

If you notice dark spots, especially around areas where your fingers frequently touch, like the fretboard, or if there’s a buildup of gunk near the sound hole or on the body’s back and sides, it’s a clear indicator that a superficial wipe-down won’t suffice.

Sticky or Grimy Feel

When playing your guitar, if the neck feels sticky or the body has a thin layer of residue, it’s a tactile sign that you need to give it more than a quick once-over.

Foul Odor

Believe it or not, guitars can develop a particular ‘smell’ over time, especially if they’re frequently played in smoky environments or are exposed to humidity. A musty or foul odor from your guitar indicates that a deep cleaning session is on the horizon.

Long Periods of Storage

If you’ve had your guitar in storage for a significant amount of time and it hasn’t seen the light of day in months or even years, performing a deep clean before playing it again is a good practice. This ensures that any dust or critters that may have settled during its hiatus are appropriately dealt with.

Post-Gig or Outdoor Play

After a night of performing or an outdoor playing session where your guitar was exposed to various elements, it might need more than just a casual wipe-down. Sweat, atmospheric changes, or even spilled drinks can necessitate a comprehensive cleaning.

It’s worth noting that while deep cleaning ensures the longevity and hygiene of your guitar, excessive and frequent deep cleaning can be counterproductive. The key is finding a balance, typically leaning on regular maintenance to prevent the necessity of frequent intensive cleaning sessions.

Common Cleaning Product Substitutions for Your Guitar

Often, you might find yourself not having the specific cleaning products recommended for your instrument. Whether you’re looking to go green, save some money, or simply caught in a bind, several household items can double up as effective guitar cleaning solutions. Here are some product substitutions that can come to your rescue:

  • White Vinegar and Water Solution: This age-old cleaning solution works wonders on the glossy finish of your guitar’s body. A diluted mixture of white vinegar and water can help remove smudges and fingerprints, bringing back the shine. However, remember to use it sparingly and wipe it off thoroughly with a soft cloth.
  • Lemon Oil as Fretboard Conditioner: Lemon oil is a popular choice among guitarists as a fretboard conditioner. It helps clean the grime off the fretboard and also nourishes the wood. Just a few drops on a soft cloth can go a long way. However, be cautious not to overdo it, as too much oil can soften the wood.
  • Baby Wipes: In the absence of specialty guitar wipes, unscented baby wipes can be a quick and effective way to wipe down your guitar body. They are gentle and won’t harm the finish. However, ensure they don’t leave any residue and are followed up with a dry cloth.
  • Old T-shirts: Instead of investing in special cloths for guitar cleaning, old cotton T-shirts can be repurposed as excellent wiping cloths for your guitar. They’re soft, lint-free, and won’t scratch the surface.
  • Baking Soda: Got some stubborn spots or fret gunk? A paste made from baking soda and water can act as a gentle abrasive to scrub away the dirt. However, it’s essential to be gentle and thoroughly remove all residues after cleaning.
  • Olive Oil: In a pinch, a tiny amount of olive oil can be used to polish your guitar’s body. It provides a beautiful sheen but should be used in moderation to prevent buildup.
  • Toothbrush: While not a product substitution per se, a soft-bristled toothbrush can be an excellent tool to clean hard-to-reach areas, especially around the tuning pegs or bridge.
  • Cornstarch: Believe it or not, cornstarch can act as an effective polisher. Just sprinkle a little on a soft cloth and rub it on the guitar’s body. It helps in removing light scratches and buffs the guitar to a shiny finish.
  • Eco-friendly Soap: If you’re keen on an eco-friendly cleaning regime, opt for a mild, biodegradable soap mixed with water to clean the surface grime off your guitar. Ensure the solution is well-diluted, and always wipe down with a dry cloth after.

When opting for substitute guitar cleaning products, always test alternative solutions on an inconspicuous part of your guitar first to ensure they don’t damage or discolor the finish. While these hacks can be handy, having specialized guitar cleaning products in your arsenal is always recommended for the best care of your instrument.

Cleaning Products to Avoid for Your Guitar

When it comes to maintaining your guitar’s pristine appearance and sound quality, it’s just as important to know what not to use as it is to know what to use. Some household products, while great for other purposes, can harm your guitar’s delicate finish, wood, and hardware.

  • Alcohol-Based Cleaners: While alcohol might seem like an effective cleaner, it’s too harsh for a guitar’s finish. It can lead to dullness, discoloration, or even strip the guitar of its protective layer.
  • Furniture Polish: These often contain silicone, a big no-no for guitars. Silicone can interfere with any future repairs, particularly when it comes to refinishing, as most finishes won’t adhere correctly to a surface contaminated with silicone.
  • Window Cleaners: Products like Windex might seem harmless, but they contain chemicals that can react with your guitar’s finish, leading to cloudiness or discoloration.
  • Undiluted Vinegar: While a diluted vinegar solution can be a suitable substitute in a pinch, undiluted vinegar is too acidic and can harm the guitar’s finish.
  • Bleach or Harsh Disinfectants: These are far too strong for a guitar’s finish and can cause severe discoloration and damage.
  • Petroleum-based Products: Such products can damage certain types of guitar finishes and can also leave a greasy residue, which can attract more dirt.
  • Abrasive Scrubs or Scouring Pads: These can scratch the guitar’s surface, leaving permanent marks. Always opt for soft cloths when cleaning your guitar.
  • Aerosol Sprays: Some aerosol sprays, especially those not designed for guitars, can leave residues that are hard to remove and can even affect the finish.
  • Heavy Oils: Thick oils, like motor oil, are unsuitable for a guitar. They can make the guitar sticky and may seep into the wood, affecting its tone.
  • Acetone or Nail Polish Remover: Extremely hazardous, these can instantly damage a guitar’s finish, leading to spots and cloudiness.
