Type of RV Antifreeze: Before you can start looking at available options for an RV antifreeze solution, you should first understand the different types of options available on the market and decide which one is the right one for you. Right now, you can go with Ethanol-based, Propylene Glycol-based, or Propylene-Ethanol mix RV antifreeze for your RV. We will discuss these options in detail in our buying guide to give you a better idea. Temperature Rating: Almost all antifreeze solutions designed for an RV have a temperature rating. Based on its application, the temperature rating is a very crucial factor and has a large impact on its application. You need to pick up an RV antifreeze solution based on the surrounding temperature. Generally, an RV antifreeze solution with -50 degrees Fahrenheit rating is good enough for most applications. Fluid Concentration: Another factor that affects the application of the RV antifreeze solution is its fluid concentration. While some options are pre-diluted, you will have to dilute yourself before application. As you can imagine, pre-diluted options are generally a better choice since you don’t have to do much with these solutions except pour them into the system. However, concentrated options give you better control over the performance and allow you to modulate the solution based on the surrounding environment.
Today, we are going to talk about the best options available out there for an RV antifreeze. These options are carefully handpicked based on the features they offer as well as their performance, making them suitable for a vast majority of RV plumbing and exhaust systems. So, you should take a look at all of our choices before you decide which of these option is right for you.You can also refer to our “Buying Guide” for the best RV antifreeze to check some crucial factors of an RV antifreeze that will help you with your decision.

Buying Guide For The Best RV Antifreeze
If you love to go out on a camping trip, the best idea would be to take out your RV so that you can save a lot on the trip. And unlike a tent, you will get a lot more comfort and warmth inside your RV, which is quite scarce during the winter season. But, you will also face some problems during winter seasons inside your RV, especially if you live in a relatively colder region. A lot of RV plumbing systems and exhausts are frozen during winter, and it is quite difficult to get these systems cleaned up. However, we have a great solution for that called the RV antifreeze solution. These are chemical compounds designed to keep the plumbing system of an RV in ideal condition. There are many different types of RV antifreeze solutions available on the market right now that you will find compatible with your RV. To avoid any sort of confusion, we have picked up the best options for you on this list. You can also check out our buying guide, which is specifically designed to provide important information about the specifications of these solutions to help you pick up the best option.
1. Type of RV Antifreeze Solution
Before you dive into the available options for an RV antifreeze, take a step back and first check out what type of options you can get and which of these options are compatible with your RV. There are mainly 3 types of RV antifreeze solutions available on the market, each offering its own advantages and limitations. So, you should first take a look at these types and then decide which options seem to be the best for you.
Ethanol-based RV Antifreeze
The most common type of RV antifreeze solution available on the market right now is Ethanol-based RV antifreeze. This solution is easily available on the market and used for a wide range of applications. This compound is also comparatively cheaper, so a lot of buyers prefer to get an Ethanol-based RV antifreeze. However, Ethanol-based RV antifreeze is also infamous for causing troubles with your RVs plumbing system in the long run. And because of alcohol content, these solutions are highly flammable.
Ethanol-Propylene Mixture RV Antifreeze
This is a slightly pricier option for an RV antifreeze solution compared to Ethanol-based RV antifreeze. However, this is a much safer choice for all types of RV plumbing systems, and it is also created with a completely non-toxic solution. An Ethanol-Propylene mixture also avoids some common problems that you would observe with an Ethanol-based RV antifreeze, such as dried out rubber gaskets. But since there is still alcohol content in this solution, you will notice a rather strong smell even after flushing out the solution.
Propylene Glycol-based RV Antifreeze
This is the most premium option that you can find for an RV antifreeze solution right now. But, it is also the safest option compared to other choices as it is completely non-toxic and does not contain any alcohol content at all. So, it is not flammable, and it also does not have a strong smell like other alternatives. Another strong suit of the Propylene Glycol-based solution is that it also works as a lubricant for your system, making your plumbing system even more efficient. But, it is quite hard to find this option in a standard hardware store.
2. Temperature Rating
Whichever type of RV antifreeze you are choosing, you need to carefully understand its parameters so that you can get an idea about its performance and reliability. For that, you need to know about the temperature rating provided for the solution. Any standard RV antifreeze solution will come with burst protection with a temperature rating dropping as low as -50 degrees Fahrenheit. So, such solutions are ideal for a lot of colder regions. But if you are talking about a place where you are likely to face snowfall, it would be better to go with a solution with a temperature rating going as low as -100 degrees Fahrenheit, just to be on the safe side.
3. The versatility of Application
Another factor to think about before you buy an RV antifreeze solution is its versatility of application. While almost all of these options are designed to be used with the plumbing or flooring system of an RV, you can also use most of these options for other applications such as home applications, ATVs, snowmobiles, and much more. For that, the solution should be compatible with a variety of commonly used metals in the plumbing system such as brass, copper, and even PVC and plastic pipelines. A lot of premium options for an RV antifreeze solution can be used as an all-in-one winterizing kit that can prepare your system for the upcoming winter as well as dehumidify it to prevent freezing altogether. And for multiple applications, you will also need a sufficient quantity of the solution or multiple bottles for longer shelf life.
4. Safety Considerations
Apart from the performance, one more factor that can affect your choice of the best RV antifreeze solution is its safety rating. You shall always go with a safe option that has a non-toxic rating, ensuring that the solution is safe for domestic as well as RV applications. A lot of RV antifreeze solutions are also used in an RVs drinking water supply system, making the safety rating even more important. For that reason, we will recommend going with a Propylene Glycol-based antifreeze solution that has an FDA-approval along with an eco-friendly compound. Other types of RV antifreeze solutions usually contain alcohol which makes the solution highly flammable and toxic, not to mention hazardous around children and pets.
