Getting your RV ready for winter is crucial to keep its plumbing safe from the harsh cold temperature. However, using the wrong anti-freeze formula can lead to cracked pipes and expensive fixes.
So how do you pick one? To find the best RV antifreeze, we spoke with a bunch of RV enthusiasts and experts in this field. According to them, the below factors are game-changers in choosing the right one.
- Temperature Rating: Select an antifreeze that can handle temperatures below the expected or recorded lowest temperatures of your area. Ideally, it should protect down to at least -50°F to ensure your RV’s water system doesn’t freeze and crack.
- Safety: Choose a non-toxic, biodegradable antifreeze that’s safe for all plumbing systems. Prefer products labeled as “GRAS” (Generally Recognized as Safe) by the FDA.
- Concentration: RV antifreeze comes in two kinds: concentrated (cheaper and longer-lasting but requires dilution before use) and pre-diluted (ready to use but with a shorter shelf life). Pick the one that suits your convenience.

Factors to Consider When Choosing RV Antifreeze
As winter gets closer, it’s really important to protect your RV’s plumbing system. One key thing to do is pick the right antifreeze. There are lots of choices out there, so it’s important to know what to consider when making your decision.
1. Type of RV Antifreeze Solution
There are two main types: propylene glycol and ethylene glycol. Propylene glycol is the better choice for RVs because it’s non-toxic, making it safer for use in water systems that you might drink from. Ethylene glycol, while it works well, is toxic and should be avoided in RVs, especially if there’s a risk of accidental ingestion.
2. Temperature Rating
This rating indicates how well the antifreeze can handle freezing temperatures. Selecting a product with a suitable temperature rating for your travel or storage location is crucial. Lower temperature ratings offer stronger protection in colder areas, helping to keep your RV’s plumbing safe even during sub-zero weather.

It’s important to think about how versatile the antifreeze is. Certain RV antifreeze options are made for specific purposes, like winterizing plumbing or safeguarding pools and spas. Choosing a versatile product that works in different situations makes things easier and more cost-effective. You can handle various winterization tasks with just one solution.
4. Environmental Impact
Considering the environmental impact is important. Seek out RV antifreeze options that are eco-friendly and biodegradable to reduce harm to the environment. Opting for environmentally conscious products not only safeguards natural resources but also protects wildlife and ecosystems in the places you visit.

It’s important to focus on safety when choosing RV antifreeze. Look for products labeled as non-toxic and safe for use in drinking water systems. Always follow correct handling and disposal instructions to keep yourself, your pets, and the environment safe.
