Dunlop Björn Gelotte Artist-Selected Custom Guitar Strings

B · Low PFAS

Lower PFAS concern; steel guitar strings lack typical PFAS-prone coatings.

Verdict: BuySteel/nickel-plated strings pose minimal established chemical hazards; no brand safety issues on record; standard guitar string safety profile.

Guitar strings are metal-based products (steel, nickel-plated wire) with no documented reason to contain PFAS. Dunlop has made no PFAS claims either way. No public lab data or recalls exist for this product category.

The full breakdown

What it's made of and why it matters

Dunlop Björn Gelotte strings are steel-core wire wound with nickel-plated steel wrapping, a conventional formulation for electric and acoustic guitars. Nickel plating provides corrosion resistance and tonal stability; steel cores offer durability under tension. This material class does not typically involve the coatings, flame retardants, or synthetic polymers that introduce common chemical contaminants into other consumer products.

The brand's record and disclosure

Dunlop (a Jim Dunlop company subsidiary) maintains no publicized material safety disclosures or third-party certifications specific to guitar strings. No recalls, safety complaints, or chemical hazard statements have been established in public records for this product line. The brand's silence on PFAS and other chemical practices is typical for the musical instrument string category, where regulatory scrutiny is minimal.

How it compares in its category

Guitar strings across brands (Ernie Ball, D'Addario, GHS, Fender) follow similar steel and nickel-plated construction with no material differentiation in safety profiles. Artist signature strings like this Björn Gelotte variant typically differ only in gauge, winding density, or alloy composition for tone, not chemical safety. This product sits squarely in the low-hazard middle of the category.

If you buy it

Replace strings when they show visible rust, discoloration, or tonal dullness (typically 1-3 months depending on play frequency and sweat exposure). Store in a dry environment to slow nickel oxidation. Wash hands after playing extended sessions if you have nickel sensitivity, as skin contact with plated strings can trigger dermatitis in susceptible individuals. No special disposal precautions are required; strings are recyclable steel scrap.

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.”

Possible

Nickel contact dermatitis

Nickel-plated strings can leach trace nickel ions during prolonged skin contact, especially with perspiration. Individuals with documented nickel sensitivity may experience localized irritation on fingertips and palms; this is a known issue in the string-playing community but not a product defect.

None known

Zinc or cadmium in alloy cores (legacy concern)

Modern Dunlop strings use steel-nickel formulations without reported cadmium or excessive zinc. No test data or recalls document heavy metal leaching from this product line into skin or saliva during normal playing.

None known

Rust or oxidation byproducts

Nickel plating prevents interior steel oxidation under normal storage and use. Degraded or corroded strings do not release toxic rust dust into air or ingested through contact; they simply lose tone and require replacement.

None known

Inhalation hazard from string dust or fibers

Guitar strings do not shed fibers, microplastics, or particulate matter during playing or storage. No respiratory risk is documented or plausible for this material class.

None known

Coating degradation or delamination

The nickel plating is integral to the steel substrate and does not flake or peel under normal playing conditions. No recalls or complaints exist for coating failure exposing raw steel to skin.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
