D'Addario Acoustic Guitar Strings XS 80/20 Bronze Coated
Lower concern, acoustic guitar strings composed of well-established metals with no known PFAS application.
D'Addario XS strings are bronze-core wire with a bronze coating. There is no established reason PFAS chemicals (which serve nonstick, waterproof, or grease-resistant functions) would be used in acoustic guitar string manufacture.

The full breakdown
What it's made of and why it matters
D'Addario XS strings use an 80/20 bronze core (copper-tin alloy) with a phosphor-bronze coating. These are metals with decades of safe use in stringed instruments; neither copper nor tin leaches into food or skin under normal playing conditions, and both are essential dietary minerals in trace amounts. The coating protects the core from corrosion and extends string life without introducing synthetic polymers or adhesives that would off-gas or degrade.
The brand's record and disclosure
D'Addario is a privately held American manufacturer with no major product safety recalls related to acoustic strings on public record. The company does not prominently advertise material safety certifications (ISO, OEKO-TEX, or similar), but this is typical across the guitar string industry, where regulatory oversight is minimal. No established environmental or labor controversies specific to this product line are documented in consumer safety databases.
How it compares in its category
Acoustic guitar strings vary primarily in core alloy (80/20 bronze, phosphor bronze, or nickel-plated steel) and winding material. The 80/20 bronze choice in this product is one of the most traditional and least chemically complex options available, with a longer track record of safe use than modern polymer-coated or synthetic-core alternatives. D'Addario is a category leader; competing premium brands (Elixir, Martin, GHS) use similar metallurgies or add polymer coatings that introduce low-level off-gassing risks.
If you buy it
Store strings in a cool, dry place; humidity and salt air accelerate oxidation but do not pose health risks. Replace strings every 1-3 months depending on playing frequency and sound quality preferences, not on safety grounds. Wash hands after playing if you have sensitive skin, as trace copper exposure can rarely trigger contact dermatitis. No special disposal precautions are needed; bronze strings are recyclable as mixed metals.
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.”
Metal leaching (copper/tin)
Guitar strings do not contact food or prolonged skin surfaces under normal use. Copper and tin are not classified as food contaminants in this application; no reported incidents of toxicity from acoustic string contact.
Coating degradation and particulate release
The phosphor-bronze coating may chip or flake with heavy use or storage in humid conditions. Any released metal particles are inert and pose no inhalation risk at typical exposure levels, but worn strings are replaced for tone quality, not safety.
Allergic contact dermatitis (copper sensitivity)
Individuals with documented copper allergy or hypersensitivity may experience localized skin irritation from prolonged string contact on fingertips. This is rare and would be evident within the first few hours of playing; switching to nickel-plated or nylon-core strings would resolve it.
Microbial contamination from storage
Metal strings do not support bacterial growth. Risk only applies if strings are stored in waterlogged or visibly moldy conditions, which users would immediately recognize and discard.
Heavy metal content in alloy
80/20 bronze and phosphor bronze alloys meet industry standards and contain no lead, cadmium, or other restricted heavy metals. D'Addario strings are used by professional musicians and educators with no documented health alerts.
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.
