303 Fabric Guard
Skip. Fabric guard products commonly use PFAS; no disclosure here.
303 Fabric Guard is a stain and water repellent for upholstery. The brand does not disclose PFAS content or ingredients, raising concern for typical water-repellent coating chemistry.

The full breakdown
What it's made of and why it matters
303 Fabric Guard is a silicone-based fabric protectant designed to repel liquids and stains from upholstery, carpets, and textiles. Silicone polymers themselves are chemically inert and low-toxicity when cured, but the solvent carrier and any additives (surfactants, stabilizers, water-repellent boosters) are what determine safety risk. Many silicone fabric treatments use fluorinated compounds or PFAS-containing chemistry to achieve durable water-repellency, which is why Zout's silence on formulation is a red flag in this product category.
The brand's record and disclosure
Zout (a Woolite/Clorox-adjacent brand in the stain and textile care space) does not publicly disclose detailed ingredient lists or manufacturing certifications for 303 Fabric Guard. No third-party certifications (such as Cradle to Cradle or GreenGuard) are evident on the product. The brand has no prominent environmental or toxicological safety statements on PFAS avoidance, which is notable because major competitors in this category (e.g., Scotchgard, Guardsman) have faced scrutiny and some reformulation around PFAS content.
How it compares in its category
Fabric guard products are a category with high PFAS prevalence because fluorinated chemistry is cheap and effective for durable repellency. 303 Fabric Guard is a mid-market option; premium brands often make claims about PFAS-free formulas (though verification is difficult), while economy options rarely disclose anything. This product sits in a murky middle: no public commitment to PFAS avoidance and no transparent testing data, making it harder to assess than brands with explicit reformulation statements.
If you buy it
Apply in well-ventilated spaces or outdoors to avoid inhaling spray aerosols, which may carry solvent residues. Do not heat-treat fabrics immediately after application; allow full cure time (typically 24-48 hours) per label instructions. Reapply every 6-12 months depending on fabric use and washing frequency. If you are concerned about PFAS exposure, choose a competitor that explicitly certifies PFAS-free status (e.g., some eco-labeled alternatives) rather than gambling on Zout's silent formula.
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.”
Volatile organic compounds (VOCs) from solvent carriers
Silicone fabric guards typically use organic solvents (petroleum distillates or hydrocarbons) to deliver the polymer. Inhalation during application can cause respiratory irritation, headache, or dizziness in poorly ventilated spaces. Zout does not publish VOC content or solvent specification.
Skin and eye irritation from spray application
Aerosol fabric sprays commonly cause contact dermatitis or eye irritation if misused. 303 Fabric Guard is sold as a spray product, so improper application (e.g., spraying near face, on skin, or without eye protection) carries typical risk for this format.
Coating residue buildup and fabric texture change
Repeated applications of silicone-based coatings can accumulate on fabric, stiffening it, darkening color, or trapping moisture under the polymer layer. This is not a toxicity hazard but a durability and user-experience concern specific to fabric protectants.
Fluorinated polymer additives (undisclosed PFAS risk)
Although not labeled as a 'PFAS-containing' product, silicone fabric guards in this market segment often use fluorinated surfactants or water-repellent boosters to extend reapplication intervals. Zout's refusal to disclose formulation ingredients is consistent with products that may contain PFAS but do not want to attract regulatory or consumer scrutiny.
Lack of ingredient transparency and third-party testing
No public safety data sheet, ingredient list, or independent testing is available for 303 Fabric Guard. This is a transparency hazard rather than a chemical one, but it prevents consumers from making fully informed decisions about cumulative chemical exposure in their homes.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
