CarCareTruth has not received a Safety Data Sheet from the manufacturer for this product, so no GHS hazard classification can be cited. The tiers below are cautious defaults — “Beyond SDS” — translated from the product’s ingredient chemistry and how comparable formulations classify, not from a manufacturer hazard classification. Request an SDS from the manufacturer before use.

Beyond SDS: translated from the ingredient chemistry
No SDS on file; eye hazard classification is unknown. This is a liquid trigger spray, and when used on a headliner the overhead application posture creates a downward mist fallout vector toward the applicator face, making eye contact a plausible pathway independent of any confirmed H-code.

No SDS on file; skin hazard classification is unknown. Repeated pressing of a cloth against the fabric during blotting creates the main extended skin-contact pathway; nitrile gloves are a reasonable precaution for sustained sessions.

Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR Water-based, ready-to-use trigger spray that lifts oil, grease, coffee, and food stains from auto carpet and cloth seats, and is community-documented for headliner spot-cleaning. Being a liquid spray rather than an aerosol foam, headliner use needs discipline: mist lightly and blot promptly so moisture does not soak the backing board. No SDS on file, so the health score reflects missing data, not a confirmed hazard.
A ready-to-use surfactant cleaner in a 22 oz trigger-spray bottle, aimed at the greasy, food-based stains fabric collects: oil, grease, coffee, wine, ketchup, pet accidents, and makeup. The wetting agents lift soils off the fibers, and the "will not stiffen fibers" claim holds up in owner feedback, fabric dries soft rather than crusty. It sprays and blots with no dilution or rinsing. The distinction that matters for overhead headliner work is the format: this is a liquid spray, not a foam, so it deposits more moisture per pass. On a headliner it needs a light mist and a prompt blot to keep the backing board dry, and community reports note a cleaned spot can dry looking slightly different from surrounding fabric, so feathering the edges matters.
A good fit for owners spot-cleaning auto carpet, cloth seats, and floor-adjacent fabric, who also want to touch up light soiling on a standard OEM cloth headliner with careful, low-moisture application. Owners whose main job is the headliner should know a saturation-limiting aerosol foam is more forgiving on the backing board than this liquid spray, and owners of foam-backed or suede-style headliner materials should verify compatibility first, since community data for those substrates is thin. Buyers chasing deep-set smoke or pet odor should pair it with an enzymatic treatment, because this is a surfactant cleaner, not an odor neutralizer.
No safety data sheet is on file for MK37-312, so safety data reflects the disclosed product information only, and the 5.0 health score reflects that missing data, not a confirmed hazard. The front label shows no GHS signal word and the product listing carries no California Prop 65 warning, both consistent with a water-based surfactant formula, but the classification cannot be verified without the document. Used overhead on a headliner, the liquid mist falls downward toward the applicator face, so eye and inhalation exposure are more plausible than in floor-level cleaning; apply with the doors open. The dirty blotting cloth goes into the laundry, so the drain pathway is real even at low volumes. VOC is undisclosed but expected low given the water base and the brand's VOC-compliant claim.
Community and owner reports document using it to spot-clean cloth headliners, and it is water-based and ready-to-use. The catch is the format: this is a liquid trigger spray, not an aerosol foam, so it deposits more moisture per pass. Headliner backing boards are cardboard or foam and cannot tolerate saturation, so the safe technique is to mist lightly onto a cloth or the surface, blot promptly, and avoid soaking the fabric. Some owners note that a cleaned headliner spot can look slightly different from the surrounding untreated area, so feathering the edges helps avoid a visible halo.
No. It is a ready-to-use formula: spray, agitate lightly if needed, and blot with a clean microfiber. The brand and owners describe it as requiring no diluting and no rinsing, which makes it a straightforward spot-and-blot cleaner rather than an extractor solution. For heavy or set-in stains, a second light application works better than one heavy soak.
The label targets oil, grease, and coffee, and the broader listing cites food and drink spills such as wine and ketchup, along with pet stains and makeup. It uses surfactant and wetting-agent chemistry to grab soils and release them from the fibers. It is a surfactant cleaner, not an enzymatic one, so it is strongest on greasy and food-based surface stains and less targeted at deep organic odors that have penetrated the fabric.
The label specifically claims it will not stiffen fibers and that surfaces feel clean and soft after cleaning, and owner feedback generally supports the soft hand-feel. As with any liquid fabric cleaner, over-application can leave tide marks, especially on dark fabric or a headliner, so lighter application and prompt blotting give the cleanest dry-down.
No SDS has been located for MK37-312 as of July 2026. The McKee's 37 website does not host SDS documents, and the distributor archives that carry other McKee's 37 safety sheets do not have one for the carpet and upholstery cleaner. The front label shows no GHS signal word and the product listing carries no California Prop 65 warning, which is consistent with a water-based surfactant formula, but the hazard classification cannot be confirmed without the document. To request the SDS, contact McKee's 37 customer service at 1-844-852-5300.
