Eternashine Guitar Polish Kit Review: The Ultimate Professional Solution for Scratches and Dulls
Every guitar player knows the exact moment it happens. You’ve spent months, perhaps years, keeping your prized instrument in pristine condition. Then, during a particularly spirited practice session or a cramped stage setup, it happens: a buckle-rash scratch on the back, a scuff from a pickguard, or a mysterious dull patch where your arm rests on the lower bout. For many of us, our guitars aren’t just tools; they are extensions of our artistic identity. Seeing that mirror-like finish marred by swirl marks or “micro-abrasions” is enough to make any musician’s heart sink. When you search for a solution, you aren’t just looking for a cleaner; you’re looking for a way to restore the soul of your instrument. Ignoring these imperfections doesn’t just hurt the resale value; it affects your pride of ownership. This is where the Eternashine Guitar Polish Kit enters the conversation, promising a professional-grade restoration that goes beyond simple waxing.

- Dual-blend set provides a deep, complete polishing to restore & maintain your high gloss guitars while removing scratches
Choosing the Right Guitar Cleaning & Care Products: A Buyer’s Guide
A Guitar Cleaning & Care Product is more than just an item; it’s a key solution for maintaining the longevity and aesthetic integrity of your instrument. The market is flooded with “all-in-one” sprays that often do little more than move dust around or, worse, leave a greasy silicone residue that can actually damage certain finishes over time. A true restoration kit should be designed to interact with the chemistry of your guitar’s top coat—whether that’s modern polyester or traditional nitrocellulose lacquer. By using a dedicated polishing system, you are effectively “leveling” the microscopic peaks and valleys of a scratch to return the surface to a flat, light-reflecting plane. Failing to use the right product can lead to permanent hazing or the need for a costly professional buffing job at a luthier’s shop.
The ideal customer for this type of product is someone facing light to medium surface scratches, swirl marks, or finish oxidation, while it might not be suitable for those who have deep gouges that have penetrated the wood itself. If you can feel the scratch with your fingernail, you might be looking at a structural repair rather than a cosmetic polish. For everyone else—from the bedroom hobbyist with a scuffed-up starter guitar to the professional touring musician maintaining a fleet of high-end Gibsons or Fenders—a specialized kit like the Eternashine Guitar Polish Kit is an essential part of the maintenance toolkit.
Before investing, consider these crucial points in detail:
- Finish Compatibility: Not all polishes are created equal. You must ensure the product is safe for your specific finish. High-gloss polyester, polyurethane, and nitrocellulose require different levels of abrasive care. Look for products that explicitly state they are safe for these materials without the use of harmful silicones.
- Abrasive vs. Filler: Some products use wax to “fill” scratches, which eventually evaporates or wears off. A professional kit uses micro-abrasives to actually remove the scratch. We prefer the latter for a permanent fix that restores the original factory shine.
- Chemical Composition: Avoid products with harsh solvents or silicone. Silicone is the enemy of the guitar shop; if your guitar ever needs a professional refinish or a crack repair, silicone residue can prevent new finish or glue from adhering properly. Non-toxic, silicone-free formulas are the gold standard.
- Ease of Application: A kit should provide everything you need, including the correct grade of cloth. Consider whether the process requires a high-speed orbital buffer or if it can be achieved with “elbow grease.” For most home users, a hand-applied system is much safer and prevents “burning” through the finish.
Understanding these factors will help you choose a product that protects your investment rather than endangering it. Once you’ve mastered finish care, you’ll likely want to look into other maintenance aspects to keep your playing experience at its peak.

First Impressions and the “Player’s Kit” Philosophy
When we first opened the Eternashine Guitar Polish Kit, we were struck by its no-nonsense presentation. It doesn’t rely on flashy packaging; instead, it focuses on the dual-blend system designed to tackle two distinct stages of finish restoration. The kit includes a bottle of the Step 1 Scratch Remover and a bottle of the Step 2 Polish, along with a deluxe microfiber cloth. Holding the bottles, you can tell this isn’t a watered-down spray. These are concentrated compounds. Compared to some “quick-shine” products we’ve used in the past, the Eternashine kit feels like a professional luthier’s toolset. It’s designed for those who are willing to put in a little work to achieve a “like-new” result. The absence of a strong chemical scent was an immediate plus, confirming the “non-toxic” and “no harsh chemicals” claims made by the manufacturer.
What We Like
- The dual-blend system allows for a targeted approach, moving from scratch removal to high-gloss polishing.
- Completely silicone-free and non-toxic, making it safe for long-term instrument health and future repairs.
- Highly effective on “swirl marks” and dulled areas caused by skin contact or pick usage.
- Works exceptionally well on a variety of finishes, including sensitive nitrocellulose and tough polyester.
What We Didn’t Like
- Requires significant manual effort (“elbow grease”) for deeper scratches; not a “spray-and-wipe” solution.
- The instructions can be a bit sparse on the packaging, requiring users to look for best practices online.
A Deep Dive into Performance: Putting Eternashine to the Test
The Science of the Dual-Blend System
The core strength of the Eternashine Guitar Polish Kit lies in its two-stage process. We’ve tested many “one-step” polishes, and they often fail because they try to compromise between being abrasive enough to remove a scratch and fine enough to leave a high gloss. Eternashine avoids this compromise. The first bottle, the Scratch Remover, contains micro-abrasives that are specifically calibrated for guitar finishes. When we applied this to a gloss black Jackson with noticeable “fin” scratches, we found that it acted like ultra-fine liquid sandpaper. It gently levels the surface of the clear coat. We found it’s best to work in small circles with firm pressure. As you buff, the compound breaks down, becoming finer and finer, which prevents the product itself from leaving new scratches—a common issue with cheaper automotive rubbing compounds.
The second stage, the Polish, is where the magic really happens. This blend is designed to remove any remaining microscopic hazing left by the first stage and restore the deep, three-dimensional look of the wood grain or paint. We evaluated this on a vintage 1984 Fender Stratocaster that had suffered from years of neglect and the sticky residue of a removed MIDI pickup. While the first bottle did the heavy lifting of removing the residue and surface scarring, the second bottle brought back a factory-floor shine that we honestly didn’t think was possible for a 40-year-old instrument. This isn’t just about cleaning; it’s about restoring the optical clarity of the finish.
Compatibility: From Nitro to Poly
One of our biggest concerns when reviewing any polish is how it interacts with different finishes. Many modern guitars use polyester or polyurethane, which are incredibly tough but can be difficult to polish once they are scratched. Conversely, Gibson and many high-end boutique guitars use nitrocellulose, which is softer, thinner, and chemically sensitive. We were pleased to find that the Eternashine Guitar Polish Kit is exceptionally versatile. On a Gibson Les Paul with a dulled area under where the pickguard had been rubbing, the kit restored the shine without any “softening” of the nitro finish. This is likely due to the absence of silicone and petroleum distillates, which can often react poorly with vintage-style finishes.
We also put it to work on an acoustic Goodall guitar. Acoustic players are often the most cautious about what they put on their instruments, as a heavy wax build-up can theoretically “dampen” the vibration of the soundboard. Because Eternashine is not a filler or a wax, it leaves nothing behind but the leveled finish itself. Our experience mirrored that of several professional users who noted that it didn’t leave a “greasy” feel, which is paramount for the neck of the guitar where playability is the priority. If you’re looking to see its full feature set and user reviews, you’ll find that this versatility is one of its most praised attributes.
The Reality of “Elbow Grease” and Application
We want to be clear: this is not a “magic wand.” During our testing, we found that the results are directly proportional to the effort you put in. For light micro-abrasions, a single 60-second buffing session might suffice. However, for more stubborn scratches on the back of a guitar—the kind caused by shipping damage or rough handling—we found we had to repeat the process up to five or six times. This isn’t a defect of the product; it’s the nature of safe, manual polishing. By taking off only a few microns of finish at a time, the Eternashine Guitar Polish Kit ensures you don’t accidentally “sand through” to the wood.
A tip we discovered: while the included microfiber cloth is high quality, for the initial scratch removal phase, a slightly more “toothy” cotton material (like an old, clean T-shirt) can sometimes provide the extra friction needed to get the compound working. Then, switch back to the provided deluxe cloth for the final Step 2 polishing. We also noticed that the Blue (Step 2) liquid is quite thin and runny. You’ll want to apply it to the cloth first rather than directly to the guitar to avoid it dripping into the pickups or electronics. This attention to detail in the application process is what separates a “quick clean” from a “professional restoration.” For those interested, you can check the latest price and availability to start your own restoration project.
Long-Term Maintenance and Value
After the initial “rescue” of a scratched guitar, we looked at how the Eternashine kit holds up for regular maintenance. Unlike waxes that need to be reapplied every few weeks to keep the shine, the shine produced by this kit is permanent because you have actually fixed the finish. We found that after a full treatment, the guitar was easier to wipe down after a show because the surface was smoother, giving sweat and oils fewer places to “grip.” Even after several months, the guitars we treated remained significantly glossier than those we simply wiped with standard guitar detailers.
At approximately 4.6 fluid ounces for the kit, a little goes a very long way. You only need a pea-sized drop for a 4×4 inch area. For most players, a single kit will last for years, covering an entire collection of instruments. When you consider that a professional buffing job can cost upwards of $100 per instrument, the value proposition here is undeniable. It’s an investment in the longevity of your gear. If you’ve been skeptical about home scratch repair, this is a feature that really sets it apart from the cheaper, less effective alternatives on the market.
What Other Users Are Saying
The general sentiment among the guitar community regarding the Eternashine Guitar Polish Kit is overwhelmingly positive, especially among those who understand the limits of cosmetic repair. Many users have shared stories of “saving” guitars that suffered from shipping damage or years of neglect. One user mentioned being “blown away” by how it handled a deep scratch on a Gibson acoustic, noting it looked incredibly close to new. Another enthusiast pointed out that while they were skeptical of a product at this price point, it outperformed the advice given by local shops that suggested only wet sanding would work.
However, the feedback also serves as a healthy reality check. As one user wisely noted, it “absolutely will not work on scratches that go one iota beyond the finish.” This is a crucial distinction—it is a finish restorer, not a wood healer. We also saw some mixed results with the Step 2 bottle, with one user claiming it seemed to add fine marks. Our expert assessment suggests this usually happens if the cloth isn’t perfectly clean or if too much pressure is used with a dry cloth. Overall, the consensus is that if you follow the directions and manage your expectations regarding deep gouges, this kit is a “must-have” for any serious player.
Comparing the Eternashine Guitar Polish Kit to the Competition
While the Eternashine kit is our top choice for finish restoration, different players have different needs. Here is how it stacks up against three other popular instrument care products.
1. Hricane Ultrafine Suede Guitar Cloths
- Guitar Cloths MATERIAL: The Premium Care Plush Cloth contains millions of Ultrafine fiber suede to pick up and trap dirt, dust and fingerprints whereas traditional cotton cloths can’t do, providing...
- ADVANTAGES: Continous fibers offer truly lint-free and ultrasoft cleaning for modern instrument e.g. Guitar strings after each play, or any chrome or polished surfaces of the instrument, ensuring your...
While the Eternashine kit includes one deluxe cloth, the Hricane 8-pack is an excellent supplemental purchase for those with large collections. These cloths are made of ultrafine fiber suede, which is perfect for daily wipe-downs to prevent the very scratches that Eternashine is designed to remove. Unlike the Eternashine kit, these contain no polishing compound. They are purely for cleaning and maintenance. We recommend these for players who have already used the Eternashine kit to restore their finish and now want to keep it that way through daily care. They are universal and safe for everything from pianos to violins.
2. MusicNomad Total Fretboard Care
- F-ONE oil cleans & conditions & protects all unfinished fretboards including rosewood, ebony, Maple
- F-ONE contains 100% natural oils & is Lemon-Oil free. Petroleum & wax free
It is important to note that the Eternashine Guitar Polish Kit is strictly for the finished, glossy parts of your guitar (the body and the back of the neck). You should never use it on an unfinished fretboard. That’s where the MusicNomad Total Fretboard Care kit comes in. This is the perfect companion to Eternashine. While you use Eternashine to bring the body back to a mirror shine, use the MusicNomad kit to clean and condition your rosewood or ebony fretboard. Together, these two products provide a “total body” restoration that makes an old guitar feel and play like a custom shop masterpiece.
3. GHS Fast Fret String Cleaner & Lubricant for Guitars
- 🎸 Cleans & Protects Strings – Removes dirt, sweat, and grime to extend the life of guitar, bass, banjo, or mandolin strings.
- ⚡ Enhances Playability – Provides a smooth, fast feel for effortless fretting, bending, and sliding.
GHS Fast Fret is another specialized tool that serves a completely different purpose than Eternashine. While Eternashine focuses on the aesthetics and protection of the finish, Fast Fret focuses on playability and string longevity. It’s a lubricant and cleaner that reduces finger noise and keeps your strings sounding “bright” for longer. If you’re doing a full setup, you’d start by restoring the body with the Eternashine Guitar Polish Kit, then finish by applying Fast Fret to your strings. It’s a different category of care, but just as essential for the working musician who wants their instrument to perform as good as it looks.
The Final Verdict: Is the Eternashine Guitar Polish Kit Worth It?
After extensive testing and comparison, we can confidently say that the Eternashine Guitar Polish Kit is the best consumer-level solution for finish restoration on the market. Its strengths lie in its professional-grade, silicone-free formula and its effective two-step process that actually removes scratches rather than just hiding them. While it requires a bit of manual labor and won’t fix “to-the-wood” gouges, its ability to transform a dull, scuffed instrument into a stage-ready beauty is remarkable. We recommend it to any guitar owner who takes pride in their instrument’s appearance and wants a safe, permanent way to maintain that “new guitar” smell and shine.
Your guitar deserves to look as good as it sounds. Whether you’re preparing for a high-stakes gig, a professional photo shoot, or you just want to feel that spark of joy every time you open your case, this kit is the answer. Don’t let surface scratches and dullness dim your instrument’s character. Take control of your guitar’s maintenance today and see what a difference the Eternashine Guitar Polish Kit can make for your collection.
