Dunlop Nickel Wound Electric Guitar Strings
Lower concern, metal guitar strings have no known PFAS function, but Dunlop provides no public PFAS statement.
Dunlop Nickel Wound strings are primarily steel core with nickel plating, materials with no established connection to PFAS use. Guitar strings don't require water-repellency, nonstick, or grease-resistance coatings where PFAS is common.

The full breakdown
What it's made of and why it matters
Dunlop Nickel Wound strings consist of a steel core wrapped in nickel-plated steel wire. Nickel plating is chosen for durability, tone retention, and corrosion resistance during the string's lifespan. The material undergoes no heating or chemical processing during normal use, so leaching of coating components is not a documented concern for this product class. Unlike non-contact consumer goods (cookware, textiles), guitar strings are not ingested, inhaled as particles, or worn against skin.
The brand's record and disclosure
Dunlop (owned by Jim Dunlop USA, part of Dunlop Manufacturing) has no publicly documented safety recalls or chemical disclosure controversies for guitar strings. The brand does not publish a PFAS statement or comprehensive material safety data for consumer strings. This silence is typical of the guitar accessory market, where regulatory disclosure requirements are minimal. No independent testing of Dunlop strings for heavy metals or coating degradation has been made public.
How it compares in its category
Nickel-wound strings are the industry standard for electric guitars and occupy the middle ground between cheaper bronze-wound (acoustic) and premium coated strings (which add polymer layers). Dunlop is a major manufacturer with consistent quality control. Alternatives like Ernie Ball, D'Addario, and GHS use similar nickel-plating technology, so this product carries no additional risk relative to established competitors.
If you buy it
Store strings in a dry environment to prevent rust on exposed core areas after the package is opened. Replace strings every 1 to 3 months depending on play frequency and style; worn strings lose tone and may snap during bending. Wash hands after playing if you have nickel sensitivity (rare but documented in some users). No special cleaning agents or temperature restrictions apply; standard storage at room temperature is adequate.
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.”
Nickel contact dermatitis
Nickel-plated strings can trigger allergic contact dermatitis in users with nickel sensitivity, though this is uncommon. Reaction occurs from skin contact during playing, not ingestion or inhalation. Dunlop does not provide nickel content or allergen labeling.
Coating degradation and core exposure
Nickel plating wears away with use, exposing underlying steel core. Exposed steel may rust or shed small particles if strings are not replaced. Risk is low because particles are not inhaled or ingested during normal play, and rust does not migrate into food or water.
Heavy metal contamination in plating
No recalls or test reports document cadmium, lead, or other heavy metals in Dunlop nickel-wound strings. Nickel plating is an established industrial process with regulatory oversight in manufacturing. Dunlop does not publish plating composition or third-party testing data.
Microplastic or fiber shedding
Guitar strings are solid metal and do not shed microplastics or synthetic fibers. This hazard class is not applicable to this product.
Teflon-type coating or volatile organic compound offgassing
Dunlop Nickel Wound strings contain no Teflon-type coating, polymer coatings, or resins known to offgas. The nickel plating and steel core do not emit volatile compounds at room temperature.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
