-200°F Premium Non-Toxic Antifreeze

Star Brite -200°F Premium Non-Toxic Antifreeze

For the most extreme winter conditions, Star Brite's Premium -200°F Non-Toxic Antifreeze is the company's most advanced winterizing formula, built to protect potable water systems, marine engines, and fuel systems well beyond what standard -50°F or -100°F antifreeze can handle. The non-toxic, biodegradable propylene glycol formula is safe for use in drinking water systems while delivering burst protection down to -200°F.

Corrosion inhibitors help protect pipes, pumps, and engine components from rust and wear, and the formula is compatible with copper, brass, and plastic, making it suitable for use in boats, RVs, home plumbing, and industrial systems. Unlike water-system-only formulas, this one is also designed for use in marine engines and fuel tanks, so a single product can cover water lines, engine cooling, and fuel system winterization. It's ready to use at full strength, with no dilution required.

How to Winterize Water Systems

Drain the entire water system as thoroughly as possible, opening all hot and cold faucets and other outlets, then use air pressure to blow out remaining water. Drain the hot water tank and leave the petcock open, then bypass the tank by disconnecting the inlet and outlet lines and connecting them together. Attach the water pump inlet line to the antifreeze container, start the pump, and open each faucet one at a time until colored antifreeze flows from the outlet, then close it. Repeat for each low-point drain, and add antifreeze to toilets and other drains as needed.
