Ernie Ball Everlast Light Coated 80/20 Bronze Acoustic Guitar Strings
Low concern; standard bronze acoustic strings lack known Teflon-family coating coatings, though coating specifics remain undisclosed.
The 80/20 bronze material itself poses lower inherent PFAS risk than high-performance coatings. Ernie Ball does not specify the proprietary light coating, and no public testing exists.

What Ernie Ball Everlast Light Guitar Strings is made of, ingredients and materials
Ernie Ball Everlast strings use 80/20 bronze (80% copper, 20% zinc) wound around a steel core, a standard alloy in acoustic guitar strings for decades. The proprietary light coating is applied to reduce oxidation and extend string life without altering playability. Unlike some coated strings that use Teflon-type coating (Teflon) or other Teflon-family coating, bronze itself is inert when vibrating on instruments and does not off-gas at normal playing temperatures.
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.
Unknown / proprietary coating
A coating is recorded with no disclosed chemistry.
Steel core oxidation and rust
The steel core can oxidize if strings are exposed to prolonged moisture, potentially releasing iron oxide particles into the air or onto fingers. This is a cosmetic and durability issue rather than a health hazard, and the light coating is designed to mitigate it.
Undisclosed chemical additives
The proprietary coating formulation is not publicly detailed, so specific additives (plasticizers, UV absorbers, antimicrobials) cannot be verified. Industry practice and lack of reported incidents suggest the coating presents lower concern, but full transparency is absent.
What’s reassuring
Coating leachability
The proprietary light coating does not contact food or skin during normal playing. No evidence of leaching into moisture or off-gassing under standard room temperature. Coating composition remains undisclosed but poses no credible risk during instrumental use.
Metal alloy toxicity (copper/zinc)
80/20 bronze is a non-toxic standard alloy used in musical instruments, plumbing, and food-contact applications for centuries. Skin contact during playing is brief and does not cause absorption; no dermal or systemic toxicity is documented.
Teflon-type coating/Teflon-family coating in coating
No evidence that Ernie Ball Everlast uses Teflon-type coating or other Teflon-family coating coatings in this product line. Standard bronze string coatings in this category are polyurethane or polymer-based without fluorine.
How is this PFAS grade calculated?
The brand's record and disclosure
Ernie Ball is a major manufacturer with no documented product safety recalls or hazardous material controversies in the public record for guitar strings. The company does not publicly disclose the exact chemical composition of its proprietary coating, which is typical for the industry but limits independent verification. No third-party testing or certifications specifically validating coating safety have been published for this product line.
How it compares in its category
Uncoated 80/20 bronze strings are the baseline acoustic string; coated variants from Ernie Ball, D'Addario, Elixir, and others add longevity at minimal chemical risk because the coating is thin and inert during normal use. Elixir strings use polyweb or nanoweb coatings (typically polyurethane-based), which also carry no established hazards. Ernie Ball's light coating falls squarely within mainstream practice and poses no known safety disadvantage versus competitors.
If you buy it
Store strings in a cool, dry place away from high humidity to preserve the coating and reduce corrosion. Strings do not require special cleaning and should be replaced every 2-4 months with regular playing or when they sound dull and feel rough. Never ingest or expose strings to direct flame. Dispose of used strings as metal waste; they are not hazardous.
