McKee's 37 Carpet & Upholstery Cleaner

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 Amazon 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.
