Best Non-Toxic RV Antifreeze Including -50°F & -100°F

Is RV Antifreeze Toxic?

RV antifreeze is used to keep the pipes in your RV or travel trailer from freezing and bursting during the frigid winter months. RV antifreeze for freshwater systems is non-toxic and safe to use in the same pipes your potable drinking water flows through.

Even though RV antifreeze is non-toxic it’s still important to make sure all the antifreeze gets flushed out of the freshwater system when de-winterizing your RV or travel trailer. If any is left behind it can make your water taste terrible and it’s better to get it all out before you use it.

Frequently Asked Questions About RV Antifreeze

What is Propylene Glycol in RV antifreeze?

There are two main kinds of RV antifreeze. The kind that is made with Propylene Glycol and the kind that uses an Ethanol base. Both chemicals work great as a non-toxic antifreeze for fresh water systems, but there are some pros and cons to each one. You can read more about them and their differences in this article here.

Will RV antifreeze freeze?

If you’ve ever looked at a jug of RV antifreeze you’ve probably seen that it says either -50°F or -100°F. The -50°F is the most common type of RV antifreeze and it will be strong enough to protect plumbing systems in most of the climates found around the world.

RV antifreeze is not made with 100% anti-freezing chemicals and it is mixed with water. The ratios are still safe for the rated temperature but when it starts to get super cold the water in the antifreeze can freeze. That’s why you want to be sure and buy the proper strength of antifreeze for your climate.

Also, make sure to never dilute the antifreeze, that will make it so the antifreeze can freeze at warmer temperatures. Be sure to follow the instructions, so the pipes of your water system will be safe all winter long.

How do I dispose of RV antifreeze?

RV antifreeze is non-toxic and therefore septic safe. After de-winterizing your RV and flushing out the water lines just take your RV to a dump and dispose of the antifreeze in the holding tanks the same way you would black or grey water.

Never dump your RV antifreeze on the ground or in a street sewer system.

What color is RV antifreeze?

RV antifreeze is for the most part pink. To read more information about that check out this article here.

Will RV antifreeze evaporate?

RV antifreeze is made with chemicals that do not evaporate but there is also some water mixed in that will evaporate. If you are winterizing a house or RV that will be left for hot summer and cold winter months it’s a good idea to use extra strong RV antifreeze that is rated for -100°F. It’s a more potent mixture and has less water in it than -50°F RV antifreeze. After hot summer months, there should be enough antifreeze left in the system to protect it against the cold winter.

How much RV antifreeze do I need to winterize my RV or trailer?

That mainly depends on the kind of RV antifreeze you buy, how big your RV is, and what method of winterizing you use. If you have a large RV and pump antifreeze through your fresh water system until you see pink come out of every tap you are going to need a lot of RV antifreeze, 6-8 gallons at least.

If you use the blow out method to get all the water out of your plumbing you won’t need as much RV antifreeze. Some people will spend a lot of time blowing out all of the water in their RV and just dump RV antifreeze into each sink and the toilet to keep the rubber gaskets lubricated over the winter.

If you are winterizing for the first time it’s always a good idea to use more RV antifreeze so there won’t be any problems during the winter. If you bought too much and have some leftover you can always use it next year.

Will RV antifreeze rust metal?

Most RV antifreeze like the ones on this list have anti-corrosion additives and are made with chemicals that are safe for materials like metal, brass, copper, and plastic.

Can RV antifreeze go down the drain?

Yes, it can go down the drain because it’s non-toxic and septic system safe. It’s also safe for plumbing systems and won’t hurt materials like plastic and metal.
