Savarez Traditional High Tension Wound Treble
Lower concern, traditional nylon guitar strings carry minimal PFAS risk.
Savarez Traditional High Tension Wound Treble strings are wound nylon treble classical guitar strings with no disclosed chemical treatments. Nylon guitar strings are not typically treated with water repellents, non-stick coatings, or grease resistance, common PFAS-use categories.

The full breakdown
What it's made of and why it matters
Savarez Traditional High Tension Wound Treble strings are nylon-core strings with bronze or silver-plated copper wound wrapping. The treble (plain nylon) portion is chemically inert under normal playing conditions, with no known leaching risk since strings do not contact food or skin for extended periods. The metal windings are tarnish-resistant coatings applied to the copper core to extend tone life and durability. Unlike cookware or food-contact plastics, guitar strings experience no heating, moisture exposure in use, or degradation pathways that would mobilize chemical hazards.
The brand's record and disclosure
Savarez is a French string manufacturer with decades of market presence and no established product recalls or safety controversies on record for this string line. The brand does not publicly disclose PFAS testing or manufacturing statements; however, this silence is typical for the guitar string category, where regulatory disclosure is not required. No third-party testing reports of heavy metal contamination or hazardous coatings in Savarez strings are available in published safety databases. The company maintains ISO 9001 certification indicating quality control systems are in place, though this does not specifically address chemical safety.
How it compares in its category
Nylon treble strings are the baseline acoustic material in classical guitars and carry fewer known hazards than wound bass strings (which use different metal alloys and may retain more processing residue). Savarez Traditional sits in the mid-to-premium segment; competitors like D'Addario Pro-Arte and GHS use similar nylon-and-metal constructions with comparable or identical safety profiles. High-tension variants like this one do not introduce additional chemical risk compared to standard tension; the tension rating reflects physical properties only. Synthetic alternative strings (nylon replacements like Aquila) follow the same material logic and carry no documented safety advantage.
If you buy it
Replace strings every 3 to 6 months depending on playing frequency; worn strings lose tone before they pose any safety risk. Store in a cool, dry place away from direct sunlight to prevent coating degradation, though this affects tone preservation rather than safety. Do not soak or expose strings to prolonged moisture, as this can accelerate metal corrosion and residue release (though amounts are negligible given string mass and contact time). Wash hands after playing if you have sensitive skin or nickel allergies, as metal windings may contain trace nickel; this is a contact concern, not a chemical leaching hazard.
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 coating degradation (copper oxidation/tarnishing)
Bronze and silver-plated windings can corrode over months of storage or heavy use in humid conditions, releasing trace metal oxides. However, direct ingestion or skin absorption is not a plausible exposure route for strings; any risk is cosmetic (tone change) rather than health-relevant.
Nickel in metal windings
Copper alloys used in string windings may contain trace nickel as a processing byproduct. Individuals with nickel contact dermatitis may experience skin irritation on fingertips during extended play; this is a known guitar string issue across all brands, not specific to Savarez.
Nylon degradation under UV or heat
Nylon treble sections are stable under normal room conditions and do not off-gas formaldehyde or volatile compounds. No testing or incident reports exist linking Savarez nylon strings to VOC emissions or polymer breakdown hazards.
Heavy metal contamination in raw materials
No published testing or recalls document lead, cadmium, or other heavy metals in Savarez string materials. The brand does not disclose raw material sourcing or third-party metal testing, but absence of evidence of contamination is typical for this product category and manufacturer tier.
Residual processing chemicals (dyes, lubricants)
Nylon and copper windings undergo industrial processing that may leave trace lubricants or surfactants. Contact time with skin or mouth (if strings contact lips) is minimal; no incident reports exist, but new strings should be wiped before first use as a precaution.
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.
