Presidential RV & Marine Antifreeze

Presidential RV & Marine Antifreeze is a premium, ready-to-use winterization solution engineered to protect the potable water systems of RVs, boats, and seasonal properties from freeze-related damage.

Whether you’re storing your motorhome or prepping your boat for offseason storage, this high-performance RV marine antifreeze provides freeze protection down to -50°F, helping prevent cracked pipes, burst fittings, and costly repairs.

Formulated with safety and reliability in mind, this non-toxic antifreeze is suitable for all types of freshwater plumbing systems, including those used for drinking water. It’s the ideal choice for safeguarding recreational vehicles, campers, trailers, sailboats, houseboats, and seasonal cabins from winter’s harshest conditions. Importantly, its advanced corrosion inhibitors help extend the life of metal components—such as copper, brass, and aluminum—while remaining safe for rubber seals and most plastic lines (excluding acetate).

In addition to preventing freezing, Presidential RV & Marine Antifreeze also acts as a protective lubricant, helping preserve seals, gaskets, and internal plumbing components during long periods of inactivity. Its brightly colored formula allows for quick visual identification during fill and flush, reducing the chance of missed areas or overuse.

Unlike other formulas, this antifreeze is environmentally conscious—engineered to be safe for incidental contact with people, pets, and surrounding ecosystems. That makes it a responsible option for winterizing systems that may discharge into the ground, lakes, or septic systems. For optimal performance and protection, use the product undiluted.

Proudly manufactured in Cleveland, Ohio by Presidential Engineered Lubricants.
