Lower PFAS concern, cast iron grill mat is a traditional, PFAS-free material.
Lodge cast iron grill mats are made from seasoned cast iron, a material with no known PFAS coating or treatment. No Teflon-type coating or Teflon-family coating nonstick is used. This is a conventional cookware material with long safety history and lower concern for PFAS exposure.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
This mat is cast iron with a seasoned (oil-treated) surface, not a nonstick coating. Cast iron is inert at high heat and does not release volatile compounds or harmful fumes during grilling. The seasoning is simply polymerized fat that builds a natural nonstick layer over time. Unlike ceramic or Teflon-type coating-coated alternatives, cast iron cookware has no synthetic coating that can degrade, peel, or leach chemicals into food.
The brand's record and disclosure
Lodge Manufacturing is a heritage American cast iron maker with a well-established reputation for quality cookware; the company does not prominently advertise PFAS status but cast iron mats inherently contain none. Lodge has no known recalls related to chemical leaching or coating failure on grill mats. The brand does not issue detailed safety documentation for this product category, which is typical for traditional cast iron, the material itself is the safety statement.
How it compares in its category
Cast iron grill mats are among the safest in the category because they avoid synthetic coatings entirely. Competitors often use ceramic-coated steel (risk of glaze degradation) or perforated metal with nonstick sprays (potential Teflon-type coating exposure). Cast iron mats are heavier and require seasoning maintenance, but they eliminate coating-related hazards that plague lighter alternatives over time.
If you buy it
Hand-wash immediately after use with warm water and minimal soap to preserve seasoning; avoid extended soaking. Dry completely and apply a thin coat of neutral oil if seasoning appears dull. Use on gas or charcoal grills at standard grilling temperatures (up to 600F); cast iron withstands this range without degradation. Replace only if rust develops that cannot be scrubbed off, or if surface becomes severely pitted; proper care extends life 10+ years.
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.”
Coating degradation and peeling
Cast iron has no applied coating to degrade. The seasoned surface is polymerized fat, not a synthetic layer that chips or flakes into food.
Thermal fume release (Teflon-type coating/nonstick)
No Teflon-type coating or synthetic nonstick coating present; cast iron does not off-gas fumes at normal grilling temperatures.
Metal leaching (aluminum, lead)
Cast iron is stable and does not leach measurable quantities of metals into acidic or fatty foods at typical grill temperatures; no lead-based glazes or enamels used.
Rust and food contamination
If seasoning is compromised or mat is stored wet, surface rust can develop. Rust itself is iron oxide and not acutely toxic in small amounts, but flaking rust should be scrubbed off before use. Proper drying and oiling prevent this.
Physical safety (weight and handling)
36x48 cast iron mats are heavy (approximately 10-15 lbs); no chemical hazard, but users should be aware of burn risk and proper grip when placing on or removing from hot grill surfaces.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 88% 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.
