<h3>About Star Brite</h3><p><strong>Star Brite</strong> has been one of the marine industry&apos;s most trusted names since its founding in 1973. <a href="/5899-starbrite">Star Brite</a> got its start with a single automotive polish product that quickly earned a loyal following — famously demonstrated in television commercials that transformed neglected junkyard vehicles into gleaming showpieces. By the mid-1980s, the brand recognized the enormous potential of the boat care market and shifted its focus toward the unique and demanding challenges of the marine environment, eventually becoming a leading manufacturer in that space.</p><p>Today, <a href="/5899-starbrite">Star Brite</a> produces a comprehensive range of marine maintenance and care products spanning hull cleaners, waxes, polishes, teak finishes, canvas protectants, fuel additives, motor oils, and much more. What sets Star Brite apart is the philosophy behind its development process: the company is run by avid boaters who test every product on their own vessels, ensuring that only the latest technology and highest-quality ingredients make it to market. The result is a lineup built to perform in real-world conditions — not just on paper.</p><p>Star Brite products are formulated using advanced materials such as nano-polymers, chelating agents, and enzymes, and the brand places a strong emphasis on environmental responsibility. Wherever possible, formulas are made to be biodegradable and safe for use around sensitive marine ecosystems — a commitment that resonates strongly with today&apos;s conscientious boaters. Every product must pass rigorous internal testing before it earns the Star Brite name.</p><p>The brand&apos;s <a href="/5899-starbrite-specialty-cleaners-200984">Specialty Cleaners</a> represent the heart of the lineup, addressing everything from stubborn waterline stains and mildew to hull discoloration and non-skid deck grime. For boat owners looking to restore and protect metal surfaces, Star Brite&apos;s <a href="/5899-starbrite-metal-cleaners-polishes-200672">Metal Cleaners &amp; Polishes</a> deliver impressive results on aluminum, stainless steel, and chrome alike. Topside fabrics and bimini tops get their own dedicated treatment through the brand&apos;s <a href="/5899-starbrite-canvas-fabric-cleaners-protectants-waterproofing-200234">Canvas &amp; Fabric Cleaners, Protectants &amp; Waterproofing</a> products, which create durable water-repellent barriers against sun, salt, and moisture.</p><p>Teak — a hallmark of classic and quality boat construction — demands specialized care, and Star Brite&apos;s <a href="/5899-starbrite-teak-products-201056">Teak Products</a> include cleaners, brighteners, and oils designed to preserve the natural beauty of this prized wood. Rounding out the range, Star Brite&apos;s <a href="/5899-starbrite-fuel-additive-12140">Fuel Additives</a> help keep marine engines running cleanly and efficiently through enzyme treatments, stabilizers, and performance-enhancing formulas.</p><p>With a state-of-the-art manufacturing and distribution facility that supplies products to virtually every country on the globe, Star Brite continues to set the standard for what marine care products can and should be.</p>

Product Details

Star Brite 312G55 Antifreeze 50 Wintersafe is a non-toxic, propylene glycol-based antifreeze and winterizing solution formulated specifically for protecting marine, RV, and powersports water systems and engines during off-season storage. This 55-gallon drum format is ideal for marinas, dealerships, and fleet operators requiring bulk supply.

The ethanol-free, virgin propylene glycol formula is completely safe for use throughout plumbing systems, water lines, bilge systems, livewells, and raw-water cooled engines. Unlike ethylene glycol products, this formula is non-toxic and safe for use in potable water systems.

Key Features:

  • Non-toxic virgin propylene glycol formula — safe for potable and fresh water systems
  • Ethanol-free formulation prevents degradation of rubber seals and gaskets
  • 50/50 pre-mixed formula — ready to use straight from the drum
  • Protects water systems and engines from freeze damage during winter storage
  • Safe for use with copper, brass, aluminum, and all types of plastic plumbing components
  • Contains advanced corrosion inhibitors to protect all metal engine components and seals
  • Bulk 55-gallon drum for high-volume commercial and fleet applications

Star Brite Antifreeze 50 Wintersafe is the trusted choice for winterizing marine engines, inboard and outboard cooling systems, freshwater tanks, heads, and water heaters. Its broad material compatibility makes it suitable for virtually any system where freeze protection is required during storage.

Good experience!

Awesome, I would recommend them.

Greatly appreciate your prompt shipping

Customer service was nice and kind, still waiting on my return for my second product I purchased. The first purchase was perfect.

It was delivered when it said it was supposed to haven't opened it yet but look forward to seeing it

Ordered 8 11R24.5 tires... Price was good and they shipped out in a day or two. Did not receive in 2 days as promised but that was Fed X's fault not THMotorsports. Would buy from again...
