McKee's 37 N-914 Rinseless Wash V2

Both. The primary application is a bucket rinseless wash: dilute 1 oz of N-914 into 2 gallons of water, dunk a sponge or wash mitt, work one panel at a time, and dry immediately with a clean microfiber. The concentrate can also be diluted into a spray bottle for use as a waterless wash, clay lubricant, or quick detailer (the 4-in-1 marketing positioning). Most enthusiast users buy it for the bucket method because it's faster and uses less product per wash.

No. The SDS Section 15 lists no California Proposition 65 chemicals, the Amazon listing does not flag a Prop 65 warning, and SDS Section 11 confirms 'Contains no ingredients classified as carcinogens by IARC, NTP or OSHA.' This is unusual for a concentrate-format detailing product — most California-market formulas carry a Prop 65 warning for trace impurities.

Section 3 of the McKee's 37 N-914 SDS reads 'Not Applicable' — the manufacturer treats the formula as fully proprietary. This is allowed under OSHA HCS 2012 when the product is not classified as hazardous and contains no ingredients above disclosure thresholds (Prop 65, SARA 313, IARC carcinogens), but it limits independent ingredient analysis. The available data confirms VOC 0%, pH 8.0-8.5, flash point 235°F, and no acute or chronic toxicity findings in Section 11.

The V2 reformulation specifically added lubricity to reduce wipe-off marring, and McKee's positions the formula for use on paint corrected and coated surfaces. Independent dark-paint scratch-testing on this specific V2 formulation has not been verified to a citable forum source in this listing — the lubrication score reflects that conservatism, not a documented failure. As with any rinseless or waterless wash, a clean microfiber per panel and a wet panel surface are the technique requirements that matter most.

A true waterless wash sprays a ready-to-use formula onto the panel and the chemistry stays largely on the towel after wipe-off. A rinseless wash like N-914 is diluted into a bucket of water — the wash water (with suspended dirt) gets dumped down the drain at the end. Environmentally, the waterless format keeps more chemistry off the pavement; the rinseless format still uses dramatically less water than a hose wash (2 gallons versus 60-100). Both formats avoid the storm-drain runoff of a traditional driveway wash.
