DR Dragon Skin+ Acoustic Guitar Strings
Lower PFAS concern; guitar strings are not a typical PFAS application, but no brand transparency.
Acoustic guitar strings are primarily steel and brass/bronze, materials with low inherent PFAS risk. The brand makes no PFAS claims or disclosures. While string coatings could theoretically contain Teflon-family coating, this is not a known risk category for guitar strings, and no public data links Acoustic360 to PFAS use.

The full breakdown
What it's made of and why it matters
DR Dragon Skin+ strings use a steel core wound with brass or bronze wrap, a standard construction for acoustic guitars. The coating process (likely a polymer or bronze oxidation treatment) determines durability and tone but is not a typical source of consumer chemical exposure since strings are not ingested, heated, or worn against skin for extended periods. Steel and brass are inert metals with minimal leaching risk under normal playing conditions. The 'Dragon Skin' branding suggests a proprietary coating, but without published material specifications, the exact composition remains opaque.
The brand's record and disclosure
Acoustic360 (DR Strings manufacturer) has not published detailed safety certifications or chemical disclosure statements for this product line in publicly available sources. No major product recalls or safety controversies are on record for DR acoustic strings. The brand's silence on PFAS and coating chemistry is typical for the guitar string industry, where regulatory scrutiny is minimal compared to cookware or textiles. Without third-party testing or independent verification, claims about 'skin-safe' or 'eco-friendly' coatings cannot be independently confirmed.
How it compares in its category
Acoustic guitar strings are a low-risk product category overall; hazard exposure occurs only during handling and playing, not consumption or prolonged skin contact. DR strings are competitively positioned as a mid-to-premium brand with reputation for longevity and tone, but safety differentiation from uncoated steel-bronze alternatives is marginal. Most acoustic string brands (Elixir, GHS, Martin, Ernie Ball) similarly lack transparent coating chemistry disclosure. The brass/bronze wrap is less reactive than pure steel and resists oxidation better, reducing the need for aggressive corrosion inhibitors.
If you buy it
Wash hands after playing or handling strings, especially before eating, to remove any residual coating particles or metal dust. Replace strings every 3-6 months depending on play frequency; older strings shed more particles and lose tonal quality. Store in a dry environment to prevent corrosion, which can trigger oxidation byproducts. No special heating, cleaning chemicals, or storage precautions are required beyond standard guitar care.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Coating composition / proprietary finish toxicity
DR Dragon Skin+ uses an undisclosed polymer or surface treatment. Without published specifications, potential presence of heavy metals, azo dyes, or volatile organic compounds in the coating cannot be ruled out, though inhalation or dermal absorption during normal play is minimal.
Metal dust / particulate inhalation
Worn or corroded strings shed fine steel and brass particles. Exposure is low during occasional playing but could accumulate in high-humidity environments or with aggressive playing styles. Risk is further reduced if hands are washed promptly after use.
Corrosion byproducts (bronze oxidation)
Brass and bronze naturally oxidize over time, forming green or black patina. These oxides (copper and zinc compounds) are not typically toxic in the quantities present on guitar strings, but handling heavily corroded strings before handwashing is not recommended.
Heavy metals in wrap or core (lead, cadmium, antimony)
No recalls or published testing indicates contamination of DR strings with restricted heavy metals. Brass and steel are generally well-regulated in manufacturing, but no third-party certification is available for this product.
Skin sensitization from nickel or other allergens
Steel strings may contain trace nickel as a stainless steel component. For individuals with nickel allergy, direct prolonged contact with strings could theoretically trigger dermatitis, but this is rare and not documented as a concern for this brand.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
