Manufacturer source
The strongest non-lab signal in this catalog. The product, brand, or manufacturer documentation makes a direct PFAS, PTFE, coating, material, or reduction claim that can be checked against stored source URLs.
How TheUncoated evaluates PFAS claims
TheUncoated is evidence-first. A product is not promoted as a strong pick just because it says clean, non-toxic, ceramic, natural, or PFOA-free.
The review standard
Every product is evaluated against product data, material signals, category risk, source URLs, confidence, and uncertainty notes. The goal is not to prove lab safety. The goal is to show how strong the available claim is, what it depends on, and what remains uncertain.
Material-based evidence
Used when the product's food-contact or skin-contact surface is a simpler material class such as stainless steel, cast iron, carbon steel, glass, borosilicate glass, silicone, cotton, or similar lower-risk material signals.
Brand claim
A useful but weaker signal. The retail listing or brand copy makes a relevant claim, but the evidence is not as strong as clear manufacturer documentation or simple material inference.
Cleaner alternative
Used for products that may be useful substitutions because of simpler ingredients or materials, but are not treated as proven PFAS-free unless stronger product-specific evidence exists.
Weak claim or none
Products with vague clean, non-toxic, ceramic, waterproof, nonstick, stain-resistant, or PFOA-free-only claims are not treated as strong PFAS picks without additional evidence.
What gets demoted
Nonstick, waterproof, stain-resistant, grease-resistant, coated, ceramic nonstick, granite, stone, and diamond-style claims get extra scrutiny. Those terms often describe performance or marketing, not the chemistry of the food-contact or body-contact surface.
What gets indexed
Guides are indexable only when they have enough qualified products, credible sources, original educational sections, and product evidence before and after embedded product picks. Thin pages stay draft or noindex.
