Jason Markk Shoe Care Repel Spray
Skip or request PFAS disclosure; shoe repel sprays commonly use PFAS water-repellent coating chemistry, brand silent.
This water and stain resistance spray is a function historically achieved with fluorinated compounds. The brand does not publish ingredient disclosure or PFAS-free claims.

What Jason Markk Shoe Care Repel Spray is made of, ingredients and materials
Jason Markk Repel Spray is a proprietary water-repellent coating formulated for fabric and leather shoe uppers. The brand does not publicly disclose its active water-repellent coating (water-repellent coating) chemistry, which is the central safety gap, shoe repel sprays in this category historically rely on fluorinated compounds (PFAS) or silicone-based alternatives to achieve water-beading. Without disclosure, the presence of long-chain PFAS cannot be ruled out, making composition verification essential before purchase.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Product chemistry not disclosed; fluorinated water repellents dominate this category. Long-chain PFAS accumulate in body tissue and groundwater. Brand silence on this point elevates concern relative to competitors with explicit PFAS-free claims.
Source, ATSDR ↗Inhalation hazard from spray application
Any pressurized spray poses risk of aerosol inhalation during application. Specific toxicity of Jason Markk Repel spray mist is not publicly characterized, but inhalation exposure to water-repellent coating coatings should be minimized through outdoor/ventilated use only.
Skin or eye irritation from direct contact
Product safety data sheet specifics are not widely available; typical shoe repel sprays carry low-to-moderate irritation risk on mucous membranes. Accidental skin or eye contact requires rinsing; no severe incidents recorded for this brand specifically.
Off-label or over-application toxicity
Applying excessively thick coats or to interiors increases inhaled or absorbed chemical load. No specific Jason Markk incidents recorded, but standard spray safety practices (follow label directions strictly) should be observed.
What’s reassuring
Coating degradation and reapplication frequency
Jason Markk Repel Spray is marketed as durable, but durability vs. competitor products is not independently verified. Frequent reapplication may increase cumulative chemical exposure over time, particularly relevant if PFAS is present.
How is this PFAS grade calculated?
The brand's record and disclosure
Jason Markk is known for premium shoe care products but does not publicly commit to PFAS-free formulations or provide third-party testing on this product. The brand has maintained silence on fluorinated chemistry use, a gap relative to some competitors who actively promote PFAS-free or silicone-based alternatives. No major safety recalls or regulatory actions specific to this spray are on record, but the lack of transparency on water-repellent coating chemistry is a red flag for conscious purchasers.
How it compares in its category
Most mainstream shoe repel sprays (Crep Protect, Scotchgard Sport) either use PFAS or avoid disclosing chemistry. Jason Markk sits in the middle, premium positioning but no differentiation on PFAS avoidance. Brands like Nikwax explicitly promote fluorocarbon-free technology; this product does not. For buyers seeking PFAS certainty, more transparent competitors or silicone-based alternatives may be preferable.
If you buy it
Apply only outdoors or in well-ventilated spaces; inhalation of aerosolized repellent particles should be minimized. Test on a hidden shoe area first to check for discoloration or texture change on delicate leathers or suedes. Reapply every 3-6 months depending on wear and exposure intensity. Do not apply to shoe interiors or insoles, and keep away from eyes and skin contact during application.
