Spray 9

<h3>About Spray Nine</h3><p><strong>Spray Nine</strong> has been one of the most recognized names in heavy-duty cleaning since its founding in 1954. In a landmark moment for the industry, <a href="/12380-spray-9">Spray Nine</a> made history in 1956 by becoming the first company to package a cleaning solution in a spray bottle — pioneering the ready-to-use, spray-on/wipe-off cleaner category that is now a staple in garages, workshops, and engine bays worldwide. What started as an automotive cleaning product used on tires, whitewalls, and upholstery eventually grew into a comprehensive line trusted across industrial, institutional, marine, military, and DIY markets.</p><p>At the heart of the Spray Nine lineup is its signature &ldquo;Triple Threat&rdquo; formula: a single product that cleans, degreasers, and disinfects in one application. Unlike solvent-based competitors, Spray Nine relies on a water-based, non-solvent formulation that is VOC compliant in all 50 states and contains no petroleum or chlorinated solvents — making it a safer choice for both users and the environment without sacrificing raw cleaning power. The formula is EPA-registered and NSF approved (C-1 rated), a testament to its industrial credibility.</p><p>Auto technicians, manufacturers, and weekend DIYers alike have relied on Spray Nine for decades to knock out tough grease, carbon deposits, brake dust, road grime, tar, ink stains, mold, and mildew. Whether you&apos;re deep-cleaning an engine bay, scrubbing down a fiberglass hull, or washing down a marine deck, there&apos;s a Spray Nine product purpose-built for the task.</p><h3>Spray Nine Product Categories</h3><p>Spray Nine&apos;s lineup spans several high-demand cleaning categories.
