What Is RV Antifreeze? 

RV antifreeze, also known as recreational vehicle antifreeze or winterizing antifreeze, is a specialized type used to protect the plumbing system of RVs and other water systems from freezing during cold weather. 

It differs from the typical automotive antifreeze (ethylene glycol) used in car engines.

RV antifreeze is typically made from propylene glycol, less toxic than ethylene glycol and safer for potable water systems. This type of antifreeze is designed to be non-toxic and safe for human and animal contact.
