COIT · Carpet & Rug Protector Sprays
TriNova Non-Aerosol Stain Guard Fabric Protection Spray for Upholstery, Carpet, Rugs and More protect from liquid stains
Skip until brand discloses treatment formula composition.
COIT's stain guard spray uses undisclosed treatment chemistry on fabric. No PFAS claims, certifications, or ingredient transparency provided; standard stain treatments often contain PFAS.

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
TriNova's stain-guard formula is proprietary and undisclosed, making independent hazard assessment impossible. Non-aerosol spray delivery reduces inhalation risk compared to pressurized aerosol versions, but the active treatment chemistry remains a black box. Fabric protectors in this category typically use silicone-based or fluorocarbon-based repellents; COIT's specific choice is unknown. Without ingredient transparency, you cannot verify whether persistent chemicals or volatile organic compounds are present.
The brand's record and disclosure
COIT has not publicly disclosed the complete chemical composition of this product or stated a position on PFAS use. The brand's silence on treatment chemistry is a red flag for consumers seeking to avoid long-chain fluorinated compounds, which are common in stain-guard formulations. No independent certifications (e.g., GreenGuard, Cradle to Cradle) appear to back safety claims. This lack of transparency is the primary safety concern.
How it compares in its category
Many fabric protectors on the market similarly use proprietary formulas, but some brands (like Scotchgard) at least disclose active ingredients publicly. Non-aerosol delivery is an improvement over aerosol versions in terms of inhalation risk. However, the stain-guard category as a whole is dominated by products with undisclosed or PFAS-containing treatments. Alternatives with disclosed chemistry or PFAS-free certifications exist but are less common in retail channels.
If you buy it
Apply only in well-ventilated spaces or outdoors to minimize inhalation exposure to volatile components. Test on a hidden area of fabric first to check for discoloration or texture change. Allow treated fabrics to dry fully (typically 4-24 hours depending on fabric weight and humidity) before contact. Do not use on items that will be heated (near radiators, in direct sunlight) until you confirm safety, as unknown formulations may off-gas under temperature stress. Reapply according to label directions, typically every 12-24 months depending on use.
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
Non-aerosol spray format reduces acute inhalation risk, but proprietary solvents and carriers in the formula may off-gas during and after application. Drying time and ventilation are critical; inadequate air circulation can prolong exposure.
Skin and eye irritation from application mist
Spray application delivers fine particles and mist. Undisclosed surfactants or solvents could cause irritation; no product safety data sheet is publicly available to assess this risk. Protective equipment use during application is prudent.
Formaldehyde releasers in fabric resins or preservatives
No public evidence suggests this product contains formaldehyde-releasing compounds, but the proprietary formula prevents confirmation. Standard fabric protectors do not typically include these, but lack of disclosure leaves a small gap.
Residual chemical buildup on textiles with repeated applications
Multiple applications of any undisclosed formula can lead to product accumulation on fibers, potentially altering fabric feel, breathability, or releasing chemicals during contact with skin or during washing cycles. Unknown polymer or silicone base compounds could persist.
Flame retardant compounds in formula
Stain guards sometimes include or interact with flame retardants already in upholstery. COIT does not disclose whether this product contains brominated or other regulated flame retardants. Risk is low but unconfirmed.
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.
