DAMP Rid · Fabric Protection Treatment Sprays
303 Fabric Guard Water Repellent Spray
Skip. Vague formula; water repellent sprays commonly contain PFAS.
303 Fabric Guard is a water and stain repellent spray with undisclosed active ingredients. No PFAS claims or testing data available; water-repellent coating textiles often use PFAS-based chemistry.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
furniture 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
303 Fabric Guard is a spray-applied water repellent coating designed to bead moisture off upholstery, carpets, and textiles. The active chemistry is not disclosed on the label or brand website, which is a red flag for this product category. Water repellent sprays typically rely on fluorinated compounds (PFAS) or silicone-based chemistries to achieve hydrophobic properties; without transparent ingredient listing, the specific mechanism here cannot be verified. This opacity prevents informed assessment of volatility, off-gassing behavior, or potential skin/respiratory exposure during application.
The brand's record and disclosure
DAMP Rid (the parent brand) is known for moisture-control products but has not published detailed safety data sheets, ingredient breakdowns, or PFAS certifications for the 303 line. The brand does not claim PFAS-free status or third-party safety verification for this spray. No recalls or major controversies are on public record, but the silence on chemical composition is itself a transparency failure, particularly for a consumer-applied coating product.
How it compares in its category
Water repellent fabric sprays span a wide spectrum of transparency. Many mainstream competitors (e.g., Scotchgard by 3M) have moved toward disclosed formulas and PFAS-free marketing, though some still contain PFAS. The 303 Fabric Guard's refusal to disclose active ingredients puts it below category norms for consumer transparency and leaves buyers unable to compare relative safety. Silicone-based or wax-based alternatives with full ingredient lists exist and pose lower uncertainty.
If you buy it
Apply in a well-ventilated space or outdoors to minimize inhalation exposure during spraying. Avoid spraying near food, children, or pets. Allow treated fabrics to dry fully (typically 2-4 hours) before contact. Do not heat-treat (steam, hot washing) immediately after application, as this may accelerate off-gassing or coating breakdown. Reapply every 6-12 months depending on use and laundering frequency. If respiratory irritation or skin reactions occur, discontinue use immediately.
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) and off-gassing
Spray-applied coatings inherently release solvents during and after application. Without ingredient disclosure, the volatility profile and indoor air quality impact of this product cannot be assessed; users may experience odor, headache, or respiratory irritation.
Respiratory exposure during application
Spraying creates an aerosol that may be inhaled. The undisclosed formula means the toxicity of particles/vapors cannot be evaluated. Users with asthma, chemical sensitivity, or respiratory conditions face undefined risk.
Skin and eye contact during handling
The label provides minimal guidance on contact hazards. Without ingredient transparency, dermatologic or ocular irritancy cannot be predicted. Misuse or accidental splash poses unquantifiable risk.
Persistence and bioaccumulation potential (if PFAS-based)
If the active chemistry is fluorinated (common for water repellents), the coating may persist in the home environment and household dust; PFAS compounds do not degrade and accumulate in human tissue over time. This risk is probable but unconfirmed without formula disclosure.
Coating degradation and reapplication burden
Fabric coatings degrade with washing, sunlight, and wear. Frequent reapplication increases cumulative exposure to undisclosed chemicals and ambient release; no data on safe lifetime exposure limits is available for this formulation.
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.
