303 Fabric Guard 2 oz
Likely contains PFAS. No ingredient transparency from the brand.
This water and stain repellent for fabrics typically relies on PFAS ingredients, yet the manufacturer remains silent on what goes into their formula.

What 303 Fabric Guard 2 oz is made of, ingredients and materials
303 Fabric Guard is a silicone-based water and stain repellent spray designed for outdoor and indoor textiles. Silicone polymers themselves are generally stable and low-toxicity, but water and stain repellents in this product class are historically formulated with fluorinated compounds (PFAS) to achieve their water-shedding properties. The brand provides no ingredient list or chemistry breakdown for this 2 oz aerosol, making independent verification of PFAS presence impossible from public sources.
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.
Inhalation of aerosol/silicone particles
Aerosol spray inhalation can irritate respiratory tract; risk is low if used outdoors or in ventilated spaces. 303 provides no warnings specific to inhalation duration or susceptible populations.
Coating buildup and fabric property changes
Repeated applications of silicone-based protectants can reduce breathability and alter hand-feel of technical and natural-fiber textiles over time. Not a toxicological hazard but a durability and performance issue documented in outdoor gear forums.
Undisclosed volatile organic compounds (VOCs)
As an aerosol, this product likely contains solvents and propellants not listed on the 2 oz label. Typical silicone spray formulations include hydrocarbons or dimethyl ether; specific composition unknown for this brand.
PFAS
Water and stain repellents in this product class are historically PFAS-based; the brand's total silence on this chemistry strongly suggests PFAS use. No public commitment to avoiding fluorocarbon chemistry is documented.
Source, ATSDR ↗Lack of safety data sheet access
Consumer-grade 2 oz bottles typically do not include full SDS; the brand does not appear to publish them online. This limits ability to verify specific hazards or allergenic ingredients.
How is this PFAS grade calculated?
The brand's record and disclosure
303 Products (brand under Armor All/Energizer ownership) does not publicly disclose PFAS status, full ingredient lists, or safety certifications for this fabric guard line. The parent company has not made commitments to phase out PFAS-based chemistries. No product-specific recalls or safety incidents appear in public databases, but absence of disclosure is not absence of hazard. This contrasts with transparent competitors who label PFAS-free or publish safety data sheets.
How it compares in its category
Fabric protectants vary widely, some use silicone systems not linked to PFAS, others still rely on fluorocarbons. 303 Fabric Guard sits in the middle-cost segment without transparent chemistry, making comparison difficult. Brands like Nikwax and Granger's now market PFAS-free alternatives; 303's silence on this choice is a relative weakness in informed consumer markets. For outdoor gear specifically, options with silicone systems not linked to PFAS are now readily available.
If you buy it
Apply only in well-ventilated areas; aerosol inhalation of silicone particles is a minor respiratory irritant risk. Test on hidden seams first, as silicone can affect breathability of technical fabrics. Reapply every 6-12 months depending on use and washing frequency. Store away from heat and flame (aerosol can). Do not use on food-contact textiles (cloth napkins, kitchen towels). If PFAS disclosure remains unavailable and you have environmental concerns, consider switching to documented PFAS-free brands.
