Elixir Nanoweb Acoustic Guitar Strings
Avoid until coating composition is disclosed; Elixir's proprietary nanoweb raises PFAS questions.
Elixir Nanoweb strings use trademarked polymer coating for durability and water resistance, but the brand doesn't disclose the coating's chemical composition or PFAS content. The waterproofing function is typical of products where PFAS were historically common.

What Elixir Nanoweb Acoustic Guitar Strings is made of, ingredients and materials
Elixir Nanoweb strings use a proprietary polymer coating applied over a steel core, designed to extend string life by reducing moisture and dirt ingress. The coating is the core innovation, but its exact chemical composition remains undisclosed by Elixir, limiting independent assessment of leachables or degradation byproducts. Steel cores themselves are stable; the concern centers on the polymer layer and what may migrate into sweat or saliva during playing.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Polymer coating composition (unknown)
The proprietary Nanoweb formulation is not publicly disclosed. Without transparency, potential leachables (plasticizers, residual monomers) cannot be ruled out. Risk is speculative but non-zero given lack of third-party testing or safety certification.
Microplastic shedding from degraded coating
As coatings age, they may flake or shed microscopic polymer particles. Inhalation or ingestion during frequent playing is unlikely to be high-dose, but chronic exposure over years is not quantified by any published study.
What’s reassuring
Steel core corrosion and metal leaching
Steel strings themselves are stable and used across all brands. The polymer coating actually protects the core from moisture, reducing corrosion risk compared to uncoated strings. No documented cases of lead or cadmium in guitar strings.
Coating-to-skin or oral contact irritation
No published adverse event reports or dermatological studies document contact dermatitis or oral irritation from Elixir Nanoweb strings. Individual sensitivity is possible but not documented in available medical literature.
VOC or off-gassing during manufacturing or storage
Acoustic guitar strings are not typically associated with volatile organic compound emissions during normal use or storage. Manufacturing emissions are not public information, but end-user exposure is negligible.
How is this PFAS grade calculated?
The brand's record and disclosure
Elixir does not publicly disclose the specific polymer chemistry or manufacturing process of the Nanoweb coating. The company has never published safety data sheets, third-party testing results, or responses to PFAS concerns in the audio equipment space. This silence contrasts with transparency trends in consumer products; no safety certifications (e.g., FDA food-contact equivalent) have been published for the coating material itself.
How it compares in its category
Coated acoustic strings (Elixir's main market position) command a premium for durability. Uncoated alternatives (D'Addario, Martin, etc.) avoid coating chemistry entirely but wear faster and require more frequent replacement. Elixir's pricing and market dominance mean many players choose them without knowing coating composition, whereas competitors often use simpler wax or oil finishes with clearer ingredient profiles.
If you buy it
Wash hands after playing to reduce potential ingestion of coating particles or leachates through skin contact and mouth. Replace strings every 3-6 months depending on play frequency; degraded coatings may shed microparticles more readily. Store in a cool, dry environment to slow polymer degradation. If you have sensitive skin or oral sensitivity, consider uncoated alternatives or request coating ingredient disclosure from Elixir before purchase.
