Everly Sessions Phosphor Bronze Acoustic Guitar Strings
Lower concern, acoustic guitar strings are unlikely PFAS vectors; no evidence of problematic coatings.
Phosphor bronze acoustic strings use conventional metal alloys with no typical application for fluorochemicals. Guitar string manufacturing does not employ the nonstick, waterproof, or stain-resist treatments that commonly introduce PFAS.

The full breakdown
What it's made of and why it matters
Everly Sessions strings use phosphor bronze (copper-tin-phosphorus alloy) wound around a steel core, a standard acoustic guitar string construction. Phosphor bronze is chosen for tonal warmth and corrosion resistance; the phosphorus acts as a deoxidizer during manufacturing and does not pose a leaching risk in typical use. Steel cores are inert and do not degrade under normal playing tension or humidity. No hazardous coatings, resins, or adhesives are typically applied to acoustic guitar strings.
The brand's record and disclosure
Everly is a mid-tier guitar accessories brand with no publicly documented safety certifications, third-party testing, or environmental disclosures specific to string manufacturing. The brand maintains no visible stance on heavy metals, manufacturing process transparency, or hazardous substance reporting. No recalls, contamination incidents, or safety complaints have been recorded for Everly Sessions strings. This silence reflects industry-wide lack of transparency in guitar string production rather than evidence of risk.
How it compares in its category
Phosphor bronze acoustic strings are the market standard and represent one of the safest material classes in guitar accessories. Premium brands (D'Addario, Ernie Ball, Martin) and budget competitors use identical phosphor bronze or 80/20 bronze formulations with no meaningful safety differentiation. Everly Sessions pricing and material composition place it in the typical mid-market; no hazard advantage or disadvantage versus established competitors. The absence of exotic coatings or proprietary finishes minimizes chemical exposure risk.
If you buy it
Store strings in a dry environment to prevent oxidation of the windings, which accelerates natural corrosion but poses no chemical hazard. Replace when they sound dull, lose tuning stability, or show visible rust or fraying, typically every 1-3 months depending on play frequency. Wash hands after playing if you have sensitive skin, as residual bronze dust and sweat can cause minor irritation in rare cases. No special disposal precautions are needed beyond standard recycling; strings are not hazardous waste.
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.”
Heavy metal content in alloy (copper, tin)
Phosphor bronze is a stable metallic compound; no leaching into skin, saliva, or food has been documented. Metals remain bound in the alloy matrix during normal playing and do not migrate.
Steel core degradation or rust
High-carbon steel cores can corrode in humid conditions or with prolonged sweat exposure, producing visible rust. This is cosmetic and structural decline rather than a chemical hazard, but accelerated corrosion may indicate lower-grade steel in budget strings.
Surface oxidation products
Bronze naturally oxidizes, forming a thin patina; this is not toxic but may affect tone and appearance. No toxic oxidation byproducts (e.g., cadmium or lead compounds) are expected in a pure phosphor bronze alloy.
Nickel content (trace allergen risk)
Some bronze alloys contain trace nickel; individuals with nickel contact dermatitis may experience mild skin irritation where strings contact fingers or neck. Risk is low but not zero, particularly with extended play sessions.
Dust inhalation from worn string fragments
Fraying or breaking strings may shed fine bronze particles; inhalation of small amounts is not documented as a health concern. Risk is negligible during normal playing but may warrant hand washing afterward.
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.
