Canola Oil · Cast Iron Cookware Seasoning
Lodge Canola Oil Seasoning Spray 8 fl oz
Lower concern. Canola oil spray carries no typical PFAS vectors.
This is pure canola oil in a spray bottle, not a coated cookware product. Canola oil itself does not require PFAS treatments or coatings, presenting lower PFAS concern for the food product itself.

The full breakdown
What it's made of and why it matters
Lodge Canola Oil Seasoning Spray is pressurized canola oil in an aerosol can, designed for non-stick cookware seasoning and cooking. The product is predominantly triglycerides derived from rapeseed oil, with a propellant (typically isobutane or similar food-grade gas) and minimal emulsifiers or anti-caking agents. Canola oil itself is stable at typical stovetop temperatures (around 400°F) and does not release hazardous fumes under normal cooking conditions.
The brand's record and disclosure
Lodge Manufacturing is a well-established cast-iron cookware company with no documented safety violations or product recalls for this spray formulation. The company does not publish detailed ingredient disclosures or third-party certifications specific to the spray product, but the formulation is straightforward and not known to contain controversial additives. No formal stance on PFAS has been publicly stated by Lodge for this particular product line.
How it compares in its category
This spray is simpler than many competitor products, which may contain lecithin, silicone, or undisclosed emulsifiers. Compared to butter-based or vegetable oil blends, pure canola oil spray avoids dairy proteins and potential allergen concerns. It is functionally equivalent to purchasing bulk canola oil and using a standard pump or trigger spray bottle, though the aerosol format ensures finer, more even coating.
If you buy it
Use on cast iron or seasoned cookware to maintain non-stick properties; avoid applying directly to hot surfaces as the propellant may vent unexpectedly. Store in a cool, dry place away from heat sources and direct sunlight to preserve propellant integrity and prevent pressure buildup. Replace when spray function deteriorates or after 1-2 years of regular use. For cooking at very high temperatures (above 450°F), consider using bulk canola oil brushed on, as aerosol propellants may degrade more readily in extreme heat.
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.”
Propellant inhalation risk
Aerosol propellants (typically isobutane) are generally recognized as safe food additives but can cause mild dizziness if inhaled directly in confined spaces. Normal kitchen use presents negligible risk; ensure adequate ventilation if using repeatedly in a small area.
Oil oxidation and rancidity
Canola oil can oxidize over time, particularly if stored in sunlight or heat, producing compounds with potential off-flavors and minor inflammatory properties. Risk is low for a sealed aerosol product with typical shelf life of 2-3 years, but deteriorated product should be discarded.
Aluminum can leaching
Lodge spray cans are lined with food-grade epoxy to prevent aluminum contact with the oil. No documented cases of leaching from this product line have been reported, and the epoxy lining is standard across food-industry aerosol cans.
Emulsifier or additive residues
Lodge's formulation appears to contain minimal additives beyond oil and propellant. Emulsifiers or anti-foaming agents, if present, are food-approved and used in minimal quantities typical of the spray category.
Thermal degradation of propellant or coating interaction
At very high cooking temperatures (above 450°F), propellant residues or oil film may degrade or interact with Teflon-type coating or ceramic coatings on non-stick cookware. Risk is low for moderate heat use but should be considered for high-heat searing or broiler applications.
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.
