Cast Iron Seasoning Spray
Skip unless Lodge confirms no PFAS in formulation.
Lodge Cast Iron Seasoning Spray contains mineral and soy oils, which are lower concern materials. The brand has not disclosed PFAS status, which is typical for food-contact seasoning products but leaves uncertainty.

What Cast Iron Seasoning Spray is made of, ingredients and materials
Lodge Cast Iron Seasoning Spray is formulated from a mineral oil and soy-based oil blend, designed to create or maintain the polymerized oil coating that protects cast iron from rust. Mineral oil is a petroleum byproduct with no known skin or ingestion toxicity at typical exposure levels; soy oil is a plant-based triglyceride. Neither component is volatile at normal room temperature, and neither is classified as a hazardous air emission when sprayed in typical kitchen use. The formulation is free of added solvents, surfactants, or known chemical accelerants on the label.
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.
Aerosol inhalation (mineral oil mist)
Spraying mineral oil in an unventilated space may create fine mist; chronic inhalation of mineral oil aerosol is linked to lipoid pneumonia in occupational settings, but culinary use is brief and low-dose. Ventilation during application mitigates this.
Oil film buildup and rancidity
If applied too thickly or wiped incompletely, mineral or soy oil can accumulate and become sticky. Soy oil is prone to oxidation and off-flavor development over time if stored in warm or light conditions; inspect the can for metallic or rancid odor before each use.
PFAS
PFAS is sometimes used in aerosol can linings or as a surfactant in some spray formulations to improve spreadability; Lodge has not confirmed or ruled out PFAS presence. This is the largest gap in product transparency.
Source, ATSDR ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Residual propellant exposure
Standard food-grade aerosol propellants (hydrocarbon or nitrogen) are not linked to consumer health hazards at the exposure levels from culinary spray use. No specific data on Lodge's propellant choice is publicly available.
Skin or eye irritation from direct contact
Mineral and soy oils are non-irritating to skin and eyes at typical exposure levels; no burn or allergy complaints specific to this product are on record. Incidental contact during cooking is not a hazard.
The full breakdown
The brand's record and disclosure
Lodge Manufacturing has a long history as a cast iron cookware maker and maintains basic ingredient transparency on product labels and their website. However, the brand has not publicly issued a formal statement ruling out PFAS (PFAS "forever chemicals") in this or other products, despite increasing industry scrutiny of water repellency treatments in kitchen products. No recalls, lawsuits, or regulatory violations specific to this spray product are on record. Lodge's silence on PFAS is a gap, not a red flag, but it prevents full reassurance.
How it compares in its category
Seasoning sprays are a convenience alternative to brush-on or wipe-on oils for cast iron maintenance. Most competitors (including store-brand mineral oil sprays and specialty cast iron sprays) use similar mineral or vegetable oil bases with aerosol propellants. Lodge's formulation avoids added flame retardants, antimicrobial agents, or synthetic polymers common in some non-stick spray alternatives. The main trade-off is ease of use and even coverage versus the cost per use of bulk oil.
If you buy it
Use the spray in a well-ventilated kitchen or outdoors; mineral oil aerosol inhalation in high concentration is unlikely but should be avoided. Apply thin, even coats and wipe off excess to prevent sticky buildup. Store in a cool, dry place away from heat sources; mineral oil has a flash point around 360-400°F, so it is not a fire hazard at room temperature but should not be stored near stovetops. Replace the can if the spray mechanism clogs or the formulation smell changes, as this may indicate degradation or contamination.
