  • Additionally, distilled water helps to flush toxins from your body, which can lead to improved liver and kidney function. 
  • Moreover, distilled water is free of chemicals so it is also great for your skin and hair. 

So if you’re looking for a way to improve your health, consider making the switch to distilled water. Distilled water can also be used in many different industrial applications.

However, there are some people who believe that distilled water goes bad over time. If you want to know, does distilled water go bad after some time, read more. 

Is It Safe To Drink Distilled Water? 

Most of us are familiar with distilled water – it’s the kind of water that’s used in car batteries and irons. But what about drinking distilled water? Is it safe? The short answer is yes, distilled water is safe to drink. 

In fact, it’s actually more pure than spring or tap water since the distillation process removes all impurities, including bacteria, viruses, and minerals.

That said, distilled water can actually be too pure for some people. Without minerals, it can be corrosive to tooth enamel and may cause gastrointestinal distress in some people. 

For these reasons, it’s important to talk to your doctor before switching exclusively to distilled water. In summary, distilled water is safe to drink, but it may not be right for everyone. If you’re considering making the switch, be sure to talk to your doctor first.

Does distilled water go bad? 

One of the most commonly asked questions about distilled water is whether it goes bad. The simple answer is no, distilled water does not go bad.

This is because the distillation process removes all impurities from the water, including bacteria and viruses. As a result, distilled water is sterile and has an indefinite shelf life. 

However, it is important to note that distilled water can absorb contaminants from its storage container. For this reason, it is best to store distilled water in a clean, sealed container. Additionally, you should avoid using distilled water if it has been stored for an extended period of time, as it may contain harmful contaminants.

How To Tell If Distilled Water Has Gone Bad? 

In some cases, distilled water can go bad if it is not stored properly. 

  • If the bottle is left open, contaminants can enter the water and cause it to spoil. 
  • Additionally, if the water is stored in a warm environment, bacteria can grow and contaminate the water. To tell if distilled water has gone bad, look for signs of bacteria growth, such as an off odor or cloudy appearance. 
  • You should also check the expiration date on the bottle. If the water is past its expiration date, it should be discarded. 

Finally, if you are unsure whether the water is safe to drink, you can contact your local water utility for testing information. By following these guidelines, you can ensure that you are drinking safe distilled water.

How Long Does Distilled Water Last?  

While most waters will start to see some signs of degradation after just a few days, distilled water can theoretically last forever.

This is because the distillation process removes impurities from water, leaving only the H2O molecules behind. without any other molecules to interact with, the water molecules are effectively inert. 

However, it’s important to note that this does not mean that distilled water is immune to all forms of degradation. Over time, even distilled water will slowly begin to absorb carbon dioxide from the air, which can lead to a slight change in taste. 

Additionally, distilled water can pick up contaminants from storage containers, so it’s important to use clean, sealable bottles and to keep them away from potential sources of contamination.

Ultimately, while distilled water may be incredibly pure, it’s still susceptible to some forms of degradation. As a result, it’s generally best to use it within a few months of distillation.

How Can I Use Expired Distilled Water?

Expired distilled water can still be used for many purposes. 

  • If it has been stored in a clean, sealed container, it should be safe to use for watering plants or filling humidifiers. 
  • It can also be used for cleaning surfaces or as an ingredient in homemade cleaning solutions. 

However, expired distilled water should not be used for drinking or cooking, as it may contain harmful bacteria. 

The Risks Of Consuming Contaminated Distilled Water

While distilled water is often thought of as being pure, it can actually be quite dangerous if it has been contaminated. 

  • One of the most common contaminants in distilled water is bacteria, which can lead to gastrointestinal illness. 
  • In addition, distilled water can also pick up chemicals from the storage container, including lead and mercury. These contaminants can pose serious health risks, especially for infants and young children. 
  • Finally, distilled water has a very low mineral content, which can cause electrolyte imbalance and dehydration.

For these reasons, it is important to only consume distilled water that has been properly filtered and stored.

How to Store Distilled Water? 

While distilled water is a great option for those who want to avoid the impurities found in tap water, it is important to store it properly to prevent it from becoming contaminated. The best way to store distilled water is in glass bottles with tight-fitting lids. 

If you are using plastic bottles, be sure to check that they are made of food-grade material and that they have been designed for storing distilled water. It is also a good idea to label the bottles so that you can easily identify them. 

When storing distilled water, be sure to keep it in a cool, dark place. This will help prevent the growth of bacteria and algae. With proper care, distilled water can be stored indefinitely.

Storing Distilled Water for Home Appliances

Home appliances such as coffee makers, humidifiers, and ice makers require distilled water to function properly. While you can purchase distilled water from the store, it is also possible to make your own using a water distiller. 

The best way to store distilled water for home appliances is to put it in a glass or stainless steel container with a tight-fitting lid. Be sure to label the container clearly so that you do not accidentally use it for drinking water. 

It is also important to keep the container in a cool, dark place to prevent the growth of bacteria. With proper storage, distilled water can be used for home appliances and will stay fresh for months.

Storing Distilled Water for Drinking

Distilled water is a type of purified water that has had all of its impurities removed, including minerals and bacteria. As a result, it is often used in medical settings or for scientific purposes.

While distilled water is safe to drink, it can go bad if it is not stored correctly. Here are some tips for storing distilled water so that it remains fresh and safe to drink:

  • Distilled water should be stored in a clean, airtight container. Glass or stainless steel containers are best, but plastic can also be used.
  • The container should be labeled with the date that the water was distilled.
  • Distilled water should be stored in a cool, dark place. A refrigerator is an ideal location.

Distilled water can be stored for up to six months. After that, it should be replaced. By following these tips, you can ensure that your distilled water stays fresh and safe to drink.

Distilled Water Vs. Purified Water

When it comes to water, there are many different types on the market today. Two of the most popular options are distilled water and purified water.

Both of these options go through a process of filtration, but there are some key differences between them. Here are three of the most important distinctions:

1. Distilled water is made by boiling water and then collecting the steam. This removes impurities, but it also strips away minerals that can be beneficial to health.

Purified water, on the other hand, is filtered using reverse osmosis or other methods that preserve those minerals.

2. Distilled water has a longer shelf life than purified water because it doesn’t contain any minerals that can promote bacterial growth. However, it’s important to note that distilled water can pick up impurities from its storage container, so it’s still important to drink it relatively soon after purchase.

3. Finally, distilled water is typically more expensive than purified water because of the extra steps involved in its production. If you’re looking for an affordable option that still meets your quality standards, purified water is usually the better choice.

Can You Freeze Distilled Water?

While water freezes at 32 degrees Fahrenheit, the freezing point of distilled water is actually lower. This is because impurities present in regular water decrease its freezing point.

As a result, distilled water can be stored in a freezer and will remain in liquid form until it reaches a temperature of below 30 degrees Fahrenheit. 

While distilled water will not freeze solid at room temperature, it can become supercooled, meaning that it will remain in liquid form until it experiences a sudden change in temperature.

For this reason, it is generally not recommended to store distilled water in the freezer for long periods of time. However, if you need to store distilled water for emergency purposes, it can be safely frozen for short-term use.

Purchase A Home Water Distiller

Although many people take clean drinking water for granted, the truth is that not all water sources are created equal. In fact, according to the Environmental Protection Agency, nearly one in four Americans lives in an area with water that does not meet all federal health-based standards. 

While most municipal water supplies are well-regulated and safe to drink, there are a number of reasons why you might want to consider investing in a home water distiller.

First of all, distilled water is free of any impurities, including bacteria, viruses, and chemical contaminants. 

Additionally, it can be helpful for those with chronic health conditions like diabetes or kidney disease, as well as for people who take medication that can interact negatively with certain chemicals found in tap water. 

Finally, distilled water has a longer shelf life than other types of water, making it a great option for emergency situations.

If you’re looking for a way to ensure that you and your family always have access to clean, safe drinking water, a home water distiller is a wise investment. If you are wondering does distilled water go bad, then we must tell you that it does but rarely.  


Distilled water is one of the purest forms of water available. It’s made by boiling water and then condensing the steam back into liquid form. This process removes impurities, minerals, and contaminants from the water. As a result, distilled water has a longer shelf life than other types of water. 

However, it’s important to note that while distilled water doesn’t go bad, it can start to taste flat after a while. For this reason, many people prefer to use distilled water for cooking and drinking purposes rather than storing it long-term.

Now, we know the answer to the question, does distilled water go bad? Let’s discuss some most frequently asked questions about it. 

Does distilled water contain chlorine?

No. Distilled water is pure H2O. It does not contain chlorine.

Can Distilled Water Grow Bacteria?

It is possible for distilled water to grow bacteria, but it is not likely. Distilled water is boiled and then cooled to produce vapor that is collected and condensed into a bottle or container. This process of distillation kills any bacteria that may be present in the water.

However, if the bottle or container becomes contaminated after distillation has occurred, it is possible for bacteria to grow in the distilled water.

Why Should I Choose Distilled Water Over Fresh Water?

The reason to choose distilled water over fresh water is because distilled water has been filtered and purified of any impurities, while fresh water may still contain contaminants.

Distilled water is also a great choice for people who have sensitive skin, as it doesn’t contain any of the minerals or chlorine that can cause skin irritation. 

And lastly, distilled water is a great choice for use in appliances that require frequent flushing, such as humidifiers and ice makers, as it helps to reduce the build-up of lime scale and other mineral deposits.

Is distilled water in plastic jugs safe?

The main concern with drinking distilled water from a plastic jug is the potential for chemical leaching. Some chemicals that may leach from plastics include BPA, phthalates, and brominated flame retardants. 

These chemicals have been linked to a variety of health concerns, such as hormone disruption and cancer. If you’re concerned about the safety of drinking distilled water from a plastic jug, you may want to switch to using a glass jug instead. 

Final Words

If you have distilled water that is more than a year old, it is still safe to use. However, the quality of the water may have gone down over time and it may not be as effective as it once was. If you want to be sure that your distilled water is still of good quality, you can always test it before using it.
