The RV antifreeze that you use is actually very different from the antifreeze you use in your house. In a home, your antifreeze needs to be replaced every 3-4 years because of its increased risk of freezing. In an RV, there are no concerns about freezing, so allowing your antifreeze to sit outside isn’t an issue.

This means that most RV owners don’t need to replace their antifreeze as often as others. The lifespan of an RV’s antifreeze depends on many factors and can vary from year to year, so we won’t be able to give a specific number for how long it should last for any given owner.

Some things that will help protect the life of your antifreeze even longer are proper storage conditions, keeping the substance out of direct sunlight, not using super-chilled or frozen water to fill the system, and using compatible brands of antifreeze that have similar properties.

How Long Is RV Antifreeze Good For? [2023 Guide]

Antifreeze or anti-freeze is a type of liquid that helps keep the temperature inside your car’s engine below freezing. The colder the temperature, the less oxygen there is in the water, and the less likely it is that any harmful organisms will grow.

So what does this mean for how long antifreeze lasts? Depending on the type, how often you drive, and other factors, some types of antifreeze may last as little as one season while others may stand up to three years.

There are also several ways to extend its life so it keeps freezing longer. Keep reading to learn more about how long antifreeze lasts and how to keep it fresh.

How Can I Properly Store RV Antifreeze?

As you can see, the lifespan of antifreeze from year to year will vary greatly depending on a variety of factors. One thing that can help to extend the life of your antifreeze is proper storage conditions.

You should always keep your RV in a temperature-controlled space as this will help to keep the water out of direct sunlight and protect it from freezing. If you store your antifreeze outside in the sun, it could freeze and cause leaks that would be hard to find later on.

You should also avoid using super-chilled or frozen water for filling up your system as these substances are not compatible with your RV’s antifreeze. You should be sure to use an antifreeze that has similar properties as well.

Can you Reuse Antifreeze from an RV?

If you have an RV, then chances are you have a refrigerator. But do you know what goes into keeping it running? Well, the first and most obvious answer is antifreeze. This essential liquid is used to keep your refrigerator from freezing and stopping the system, which will result in damage.

If not treated properly, your RV can end up with leaks that waste valuable water and cost you money to repair or replace. Fortunately, there are ways to reuse antifreeze from your RV for an eco-friendly option instead of buying a new bottle every time. The key is knowing how to do it and finding the right solution for your specific needs and situation.

Can you Dump RV Antifreeze on the Ground?

Dumping antifreeze on the ground is not environmentally friendly. Instead, use a spray bottle to spray it on plants or vegetation in your yard or garden. You can also put it into the water and create a solution that you can use to water your plants.

If you have kids and they like to drink out of the sink or bathtub, then they can also drink from the solution that you created. You can also dump RV antifreeze in an old bucket and fill it with sand or gravel. This will help absorb any leaks that develop.

Lastly, you can reuse RV antifreeze by cooking with it! There are many recipes for using leftover RV antifreeze in meals like chilli, soup, stews, etc.

Can you put RV Antifreeze in Fresh Water Tank?

Yes, you can reuse RV antifreeze in your freshwater tank. However, you need to be careful and make sure the antifreeze is from an RV that hasn’t been used for a long time. If the RV has been used for a few weeks or less, then it may not have enough antifreeze left to be effective.

This means that you should keep your RV on a separate freshwater source in case of emergencies, like if you run out of fresh water without having enough antifreeze available.

How Do you Get the Antifreeze Smell out of a Camper?

Antifreeze is an essential component of your RV. You need it to keep it from freezing up and breaking down, but you don’t want the smell to linger. Luckily, there are ways to get rid of the antifreeze smell that some people might not be aware of.

One way is by using ammonia, which will kill the bacteria in the antifreeze. Another way is by using a strong air freshener or vaporizer like Febreze. For a more eco-friendly option, you can use baking soda and vinegar to get rid of any remaining traces of the heavy odour in your RV’s ventilation system.

It’s also wise to use a deodorizer once a month or so if you notice any odours lingering around your camper. The key is knowing how to do it and finding the right solution for your specific needs and situation.

What Does Antifreeze Do to Your RV Water Heater?

Antifreeze is made up of a mixture of ethylene glycol and propylene glycol. It’s used in motor homes because it doesn’t corrode metal parts as water does. However, it has some side effects that aren’t ideal for RV plumbing.

One main side effect is that antifreeze can create silvery-grey stains on your water heater that makes it difficult to see what the problem might be. In addition to stains on your water heater, a build-up of antifreeze can also cause leaks and defective seals in your plumbing system.

How Can I Protect Water Heater From RV Antifreeze?

When you are filling your RV’s water storage tank, it’s important to remember that antifreeze is designed for motorhomes. If you simply fill your tank as usual and then switch on the water heater, what will happen? The water in your RV would mix with the antifreeze and cause a chemical reaction.

This means that when you turn on the water, it could potentially be very dangerous. You can solve this problem by using a different type of solution in your water heater. You can use spring water or distilled water instead of antifreeze.

These two types of solutions won’t react with each other and will provide clear hot water for you to enjoy every time.


Antifreeze is designed to keep your RV’s engine from freezing up in cold weather and provide a high level of protection from the sun’s damaging rays.

It’s important to follow the manufacturer’s instructions for storing and maintaining the antifreeze to ensure its effectiveness.
