Grandma's Secret · Fabric Protectant Sprays
Non-aerosol Stain Guard, Fabric Protection Spray, Upholstery, Carpet,
Skip; stain guard sprays commonly contain PFAS, brand silent on chemistry.
Fabric protection sprays are frequent PFAS sources for water and stain resistance. Grandma's Secret discloses no ingredients or PFAS status, raising concern.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
other is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
The full breakdown
What it's made of and why it matters
Grandma's Secret lists its formula as proprietary, which is standard but opaque for stain guard sprays. Non-aerosol fabric protectants in this category typically rely on either fluorinated compounds (PFAS-class repellents) or silicone-based alternatives; the brand does not publicly specify which chemistry is used. The active coating mechanism requires either water or oil repellency at the fiber level, a function historically dominated by PFAS chemistries. Without ingredient disclosure, the repellent type cannot be verified from public sources.
The brand's record and disclosure
Grandma's Secret does not maintain public transparency on PFAS content or alternatives for this product line. No third-party certifications (such as Oeko-Tex, GOTS, or MADE SAFE) are advertised on this product. The brand has no published position on per- or polyfluorinated compound avoidance in fabric care products. This silence on chemistry is typical of smaller household product makers but leaves consumers unable to distinguish between PFAS and safer alternatives.
How it compares in its category
Most stain guard sprays and fabric protectants (including Scotchgard and professional equivalents) have historically used PFAS-based repellents, though some now offer fluorine-free lines. Grandma's Secret occupies the budget segment without marketing a PFAS-free or alternative chemistry claim, suggesting conventional formulation. Comparable non-brand alternatives with transparent PFAS-free labeling exist but are not common in the mass market. The lack of differentiation or environmental claim is a red flag in a category where chemistry alternatives are becoming available.
If you buy it
Apply in well-ventilated spaces to avoid inhalation of spray particles and volatile components. Test on a hidden area first to confirm no discoloration or fiber damage. Allow full drying (typically 24-48 hours) before use or contact with skin. Do not apply to items that will be washed frequently, as reapplication will be needed and cumulative exposure to the formula increases; instead, prioritize low-traffic upholstery or specialty textiles if protection is essential.
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.”
PFAS (per- and polyfluorinated compounds)
Stain guard sprays in this price and disclosure tier commonly contain PFAS-class repellents. The brand's silence on chemistry and absence of a PFAS-free claim suggest conventional fluorinated formulation, though no specific test data is publicly available for this product.
Volatile organic compounds (VOCs) and inhalation risk
Non-aerosol sprays still release propellants and solvent vapors. The specific solvent package is not disclosed; typical fabric protectants use alcohols or hydrocarbons that can irritate respiratory tract if applied in enclosed spaces.
Skin and eye irritation from spray contact
Repellent compounds and solvents can cause localized irritation if spray contacts skin or eyes during application. No safety data sheet or hazard labeling details are provided on publicly available product information.
Water and soil contamination from runoff
If PFAS-based, the compound will persist in treated fabrics and leach into household water and soil via washing or disposal. PFAS repellents are bioaccumulative and have been detected in groundwater near homes using treated textiles.
Lack of efficacy data and reapplication frequency
No independent durability or performance claims are published for this product. Frequent reapplication increases cumulative exposure to the spray formulation and its volatile components, particularly in households with children or pets.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
