Will RV Antifreeze Kill Grass?
RV Antifreeze, commonly used in recreational vehicles for winterizing, is often a subject of concern regarding its impact on the environment, mainly grass. The critical question that arises is: Will RV Antifreeze Kill Grass? This has been a topic of interest for RV owners and environmental enthusiasts alike.
- RV antifreeze may harm or kill grass.
- Ethylene glycol, a toxic component, causes dehydration in grass.
- Grass needs water, and antifreeze absorbs surrounding water.
- Accidental spills result in dead or dying grass patches.
- Soil composition may be altered, affecting plant growth.
- The damage depends on the spill amount and cleanup.
- Handle RV antifreeze carefully to protect your lawn.
While dealing with RV antifreeze, this question often pops up in my mind, “Is RV antifreeze toxic to plants and grass?”
It was not long before I realized that winterizing RV water pipes is essential to avoid damage due to cold weather.
However, I was also highly concerned with the antifreeze’s toxicity level and how it would affect the greenery around me if dumped in my garden area.
I found that RV antifreeze can sometimes be toxic to green life, depending on the antifreeze’s principal ingredient.
Let’s dig in to discover more about it.
So, will RV antifreeze kill grass? In most circumstances, RV antifreeze will not kill grass. RV antifreeze is made from propylene glycol, which is non-toxic and will be heavily diluted in an RV water system when it comes to emptying.
Will RV Antifreeze Kill Grass?
Plants and grass are delicate. If leaked into the soil, certain pesticides cause a reduction in the nutrient value and hamper plants’ growth.
Likewise, dispersing RV antifreeze across a garden area or backyard is dangerous. It can get absorbed into the soil, affecting the ecosystem of the surrounding plant life and even killing them.
The same goes for turf patches and mature grass. However, compared to plants, they are less susceptible to damage if RV antifreeze with mild toxicity is dispersed over the grass blades.
Now, what does that mean?
The extent to which the antifreeze can hurt green life (or grass) depends on RV antifreeze types and other factors.

Toxicity Level Variations Between RV Antifreeze Types
Different types of RV antifreeze are available in the market from multiple brands. The toxicity levels to plants and potential antifreeze poisoning also vary considerably for each type.
For me, it was necessary to comprehend and recognize these distinctions since I had plants to protect and a beloved lawn that I didn’t want to put at risk of losing a life.
Other factors that determine the antifreeze’s toxicity level include:
- its dilution, or how much water is present in the formula
- the volume or amount of antifreeze dispersed over what yardage of turf
Types of RV Antifreeze
Not all RV types of antifreeze are heavily poisonous. The product’s composition determines its toxicity level and whether it can kill grass. Some commonly available RV antifreeze types are:
- Ethanol
- Ethanol and ethylene glycol blend
- Propylene blend with ethanol
- Propylene glycol
Propylene Glycol RV antifreeze is the least toxic solution with substantial water dilution. Though plants are not safe from it, turf or grass remains fine if it dilutes substantially.
Ethanol
Ethanol is widely used as an antifreeze for automobiles. It is also available as an RV antifreeze and is highly affordable. This factor makes it popular among RV users.
However, considering the toxicity element, it is highly hazardous to plant life and grass. As ethanol is categorized as alcohol, it is potent. Its effectiveness in the RV’s plumbing system cannot be denied, but it is not environmentally friendly and can kill plants and grass immediately.
Ethanol and Ethylene Glycol Blend
RV antifreeze consisting of ethylene glycol and ethanol is also the worst option. It is suitable as an automobile antifreeze but not recommended for RV or camper winterization.
The mixture converts into oxalic acid after oxidation and becomes highly toxic. The toxicity degree can be estimated because it can quickly dry out rubber seals of toilets and faucets and create leakage.
So, it is evident that delicate creatures like plants and grass cannot withstand its toxicity. It is poisonous enough to prevent the plant’s growth and extinct grass. The concoction is harmful to humans, too, and requires careful handling.
As it has a sweet and appealing smell, children and pets are more likely to ingest the compound, which can be fatal.
Ethanol and Propylene Glycol Blend
This compound constitutes propylene glycol and ethanol. It is a blended mixture of both chemicals used extensively as RV antifreeze.
I like this solution as it works effectively for both automobiles and RVs. However, its properties do not alter much and offer similar drawbacks to green life as other RV antifreeze mentioned earlier.
The toxicity level decreases for humans but remains the same for grass due to the presence of alcohol-based ethanol.
Certain RV antifreeze brands claim to offer non-toxic variations; however, I consider such claims bogus. This is because including ethanol eliminates the product from the appropriate ones to use near grass or turf.
Propylene Glycol
Among all the antifreeze options available, propylene glycol tends to be the least toxic to turf/grass or plants. This formula is highly preferred by avid gardeners and individuals who like lush green lawns or have particular concerns for plant life.
But wait.
This does not imply that propylene glycol is the best RV antifreeze and does not affect the grass.
Specific scientific experiments have shown that propylene glycol vapors are toxic to soya beans and corn. The vaporous gas resulted in chlorosis, which destroys the leaves’ green color and causes cellular death.
So, propylene glycol does not instantly kill grass or plants but affects their growth significantly and enhances their pollen sterility.
Can I Recognize the Safer Antifreeze by Color?
Many individuals in the RV community believe it is possible to identify the most poisonous RV antifreeze by color. The perception is that the pink-colored antifreeze is safest, whereas the green one is hazardous.
I do not believe in this concept because that is not always true. The solution’s color is not a parameter to judge what primary ingredients are in the product.
So, using color as an indication is a blunder. The best tip is to read the label to find out the solution’s ingredients and whether it is the least toxic option for grass and other living creatures.
Which RV Antifreeze Type To Go For? What Do I Recommend?
With the above discussion, one thing is sure: all the ethanol-based RV antifreeze types threaten grass and immediately destroy them if they come into contact.
Propylene glycol-based RV antifreeze is not a threat to grass. It works fine if diluted heavily and distributed on a larger area using a spray. The low concentration and grass durability are two factors that may keep the grass safe.
Again, there is no 100% surety that grass will not change its color and die off.
So, I recommend none of the above RV antifreeze is suitable for grass health. Instead, working on a controlled and safe RV antifreeze disposal is a wise step towards protecting the green life.
Guidelines For Safe RV Antifreeze Disposal
Are you wondering what to do with the used RV antifreeze?
The best way to dispose of the used antifreeze is by draining it to any RV dump station. Another option is to collect into a bucket and dispose of it with proper safety measures.
I fill the tank with freshwater and run it through the shower and faucets. This flushes the lines out thoroughly. After that, I dump the tank.
During the cleaning process where antifreeze spills, take the following precautions:
- Wear protective gloves and gear to avoid absorption of chemicals by skin
- Wear a face mask to prevent or minimize inhalation of chemical fumes
- Keep children and pets away from the spill
- Absorbent pads help soak up the spilled solution
- Avoid using a hose to wipe away antifreeze since this will result in a diluted solution but will not eliminate the threat to grass, lawns, and plants.
Can I put RV Antifreeze in my Water Tank?
Yes, you can put RV antifreeze in your water tank. This question often arises when preparing an RV for winter storage. The drain valve should be closed after the water has been completely drained from the freshwater tank.
Subsequently, 4 gallons of non-toxic RV antifreeze should be poured into the freshwater tank.
This quantity is sufficient to fill the tank enough for the water pump to draw the antifreeze. This process helps prevent any residual water from freezing and causing damage to the system during colder months.
Wrapping Up
RV antifreeze contains a toxic component known as ethylene glycol, which can cause harm or even death to grass. This chemical compound works by pulling moisture out from its immediate environment, thereby dehydrating the grass, which relies heavily on water for survival.
When accidental spills of RV antifreeze happen, they often result in patches of grass that are either dying or completely dead. Additionally, these spills can alter the soil’s composition, adversely impacting the growth of other plants in the vicinity.
The extent of the damage caused is typically dependent on the amount of antifreeze spilled and how effectively it is cleaned up. Therefore, handling RV antifreeze with care is essential to prevent damage to your lawn and maintain its lush, green appearance.
