-100°F Non-Toxic Antifreeze: The Only Safe Choice for Your Boat

When it comes to winterizing your boat, the products you choose matter. Ever notice the bright pink antifreeze on the shelves at grocery or hardware stores? While it may look convenient, it’s one of the biggest mistakes you can make for your boat’s long-term health. The truth is, that pink antifreeze isn’t designed for the extreme cold we can face here in the Midwest — and using it could lead to costly engine or system damage.

The Problem with Pink Antifreeze

The burst point of pink antifreeze is just +12°F. That might work in milder climates, but it’s simply not enough to stand up to Midwest winters. On January 30, 2025, Chicago temperatures dropped to -23°F — nearly 35 degrees colder than pink antifreeze can handle. If your boat was winterized with the wrong product, your engine and water systems would be at risk of cracking and serious damage.

The Right Choice: -100°F Non-Toxic Antifreeze

Instead of taking that risk, protect your boat with -100°F (-73°C) non-toxic, biodegradable antifreeze. This marine-grade solution is designed for extreme conditions, providing freeze protection in the -58°F to -63°F range. It’s safe for both engines and drinking water systems, delivering reliable protection without harming your boat’s components. Its premium additive package prevents corrosion in aluminum, copper, brass, and solder, while staying gentle on rubber, seals, and hoses. Even better, it’s non-toxic and biodegradable — giving you peace of mind for your boat and the environment.
