Corn Oil · Cast Iron Cookware Seasoning
Lodge Canola Oil Seasoning Spray 8 fl oz
Lower concern. Liquid cooking oil product, no PFAS risk profile.
This is a liquid canola oil spray, not a coated product. Standard edible oils have no PFAS association. Typical food-grade packaging may use liners, but risk is minimal for end consumer.

The full breakdown
What it's made of and why it matters
This is a liquid canola oil product, likely delivered via an aerosol or pump spray mechanism. Canola oil itself is a refined vegetable oil approved for food use by the FDA and contains no inherent toxins when food-grade. The spray format may include a propellant (typically food-grade propane or butane in aerosols, or mechanical pump in spray bottles) and possibly lecithin as an emulsifier, both food-safe additives. No coating, ceramic, or non-stick resin is involved, so degradation hazards typical of cookware products do not apply.
The brand's record and disclosure
Lodge is a well-established US cookware manufacturer known for cast iron products; this seasoning spray is a peripheral product line. The brand does not market transparency on this specific spray's ingredient sourcing or processing details publicly available. No recalls or safety incidents on record for Lodge canola oil spray products. The brand has not issued statements on PFAS mitigation for this product category.
How it compares in its category
As a liquid cooking oil spray, this product avoids hazards common to solid non-stick cookware (Teflon-type coating fume risk, coating degradation). Compared to alternative seasoning sprays (olive oil, coconut oil, or proprietary blends), canola oil spray is neutral on oxidation stability and cost-effective. Most competitors in this category share the same minimal chemical hazard profile; differences are marginal and relate to oil type and oxidation rate rather than safety concerns.
If you buy it
Use the spray at or below the smoke point of canola oil (approximately 400°F), which makes it suitable for low to medium-heat cooking and seasoning. Do not use for high-heat searing or broiling. Store in a cool, dark place away from direct sunlight to prevent rancidity and maintain oil quality; check the expiration date. For aerosol cans, ensure propellant integrity and do not expose to temperatures above 120°F. Replace annually or when oil develops an off smell, indicating oxidation.
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.”
Oil oxidation and rancidity
Liquid canola oil exposed to heat, light, or prolonged storage will degrade over time and produce off-flavors and reduced nutritional value. This is a quality issue rather than a toxicity hazard, but oxidized oils may contain mildly inflammatory compounds.
Propellant or additive residues (if aerosol format)
If this product uses a pressurized aerosol, the propellant (typically food-grade butane or propane) is not known to pose safety risks at typical use levels. No established hazard on record for this specific product.
Allergen cross-contamination
Canola oil itself is not a major allergen, but manufacturing facilities may process tree nuts or other allergens. Product labeling should be checked for allergen warnings, though none are anticipated for pure canola oil.
Smoke-point exceedance and thermal degradation
Using canola oil spray above its smoke point (400°F) will break down the oil and generate acrolein and other thermal degradation compounds, which are respiratory irritants. This is a misuse hazard, not a product defect.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 92% 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.
