Finally, we’ll give you some tips on how to use it safely.
What is Isopropyl Alcohol and How It’s Made?
Isopropyl alcohol is manufactured using natural gas or propane as a feedstock. These hydrocarbon gasses are converted into acetic acid, which is then combined with water to create isopropyl alcohol.
Isopropyl alcohol has a number of uses both domestically and industrially. It’s commonly used as a cleaning agent, solvent, antiseptic, and disinfectant. You’ll find it in many household products like rubbing alcohol, hand sanitizers, first aid kits, and more.
The majority of isopropyl alcohol produced commercially is mixed with water and used as rubbing alcohol. It’s also present in a number of other products like cosmetics, deodorants, and medications. [1], [2], [3]
Benefits of Using Isopropyl Alcohol for Cleaning
But why is isopropyl alcohol such a popular choice for cleaning? Isopropyl alcohol is commonly used to clean electronic devices because it’s an effective way to remove built-up dirt, dust, and grime. It can also be used to remove fingerprints and smudges from cell phones, tablets, laptops, and other devices. Here are the factors that make isopropyl alcohol a great choice for cleaning electronics.
It can clear many contaminants with no issues
One of the main reasons isopropyl alcohol is used for cleaning electronics is that it can clear away a variety of contaminants. It’s especially effective at removing oils, grease, and fingerprints. And since it evaporates quickly, you don’t have to worry about water damaging your devices.
It leaves no traces of residue
This makes it ideal for cleaning sensitive electronic components like circuit boards and motherboards.
It’s a strong disinfectant
In addition to being an effective cleaner, isopropyl alcohol is also a powerful disinfectant. When used correctly, it can kill up to 99.99% of bacteria, viruses, and fungi. This makes it a great choice for cleaning items that come into contact with your skin, like cell phones and keyboards.
It’s affordable
Isopropyl alcohol is one of the most affordable cleaning agents on the market. It’s also easy to find and can be purchased at most stores. While higher percentages of isopropyl alcohol cost more, they’re still relatively affordable.
It’s non-toxic
Isopropyl alcohol is a non-toxic substance that poses no risk to human health. In fact, it’s often used in rubbing alcohol and hand sanitizers. However, it’s important to note that isopropyl alcohol can be toxic to animals. If ingested, it can cause vomiting, diarrhea, and central nervous system depression.
Other than that, it’s safe for most surfaces. Isopropyl alcohol won’t damage most electronic devices. However, it’s always important to test it on a small area first to be sure. Generally, the higher the percentage of isopropyl alcohol, the less likely it is to damage your electronics. [1], [3]
What Percentages Next to Isopropyl Alcohol Mean?
The percentages next to isopropyl alcohols signify the concentration of isopropanol in water. For example, 70% isopropyl alcohol is 30% water. The higher the percentage of isopropyl alcohol, the greater the cleaning power but also the greater the risk of damaging your electronics.
As you may have guessed, it’s not isopropyl alcohol itself that risks damaging your electronics. The water is the real culprit here.
Water is an excellent conductor of electricity. This means that when water comes into contact with electrical components, it can cause a short circuit. A short circuit can fry delicate electronic components and render your device unusable.
Isopropyl alcohol, on the other hand, isn’t going to damage your electronics on its own. In fact, isopropyl alcohol is a common cleaning agent used in the electronics industry.
However, isopropyl alcohol can evaporate quickly, leaving behind water. If you’re not careful, this water can cause a short circuit and damage your electronics.
This is why it’s important to use the right concentration of isopropyl alcohol when cleaning your electronics. A higher concentration of isopropyl alcohol will evaporate more quickly, minimizing the risk of water damage. [1], [2], [3]
Is 91% Isopropyl Alcohol Safe for Cleaning Electronics?
So, you want to use isopropyl alcohol (IPA) to clean your electronic devices, but you’re not sure if it’s safe.
The short answer is: yes, 91% isopropyl alcohol is safe for most electronics, as long as you follow a few simple precautions. In fact, if you plan on cleaning sensitive components like circuit boards, 91% IPA is actually one of the best choices.
So we got it, when used correctly, isopropyl alcohol won’t damage most electronics as long as you use the right concentration of isopropyl alcohol and take care not to get any moisture inside the device.
If you want to be 100% sure everything goes well, you can take a step further and get yourself a 99% isopropyl alcohol. This will further reduce the risk of moisture damage, but it’s not strictly necessary. What’s more, it’s not easy to find 99% isopropyl alcohol and it’s often more expensive. [1], [2], [3]
How to Use Isopropyl Alcohol Safely on Electronics
When using isopropyl alcohol to clean electronics, it’s important to take precautions to avoid damaging the device. Use only 91% isopropyl alcohol, which you can find at most drugstores or online. Avoid using lower concentrations of isopropyl alcohol, as these can damage your precious devices.
Power off the device
To clean your electronics with isopropyl alcohol, start by powering off the device. If you’re cleaning a laptop, unplug it from the power cord. For smaller devices, like phones or tablets, remove the battery if possible.
If you can’t remove the battery, make sure the device is completely powered off before proceeding.
Apply isopropyl alcohol to a lint-free cloth
To avoid leaving behind lint or other debris, use a lint-free cloth soaked in isopropyl alcohol. A coffee filter or paper towel also works well. Gently wipe down the entire surface of the device with the damp cloth.
Don’t douse your electronics in isopropyl alcohol
It’s important not to douse your electronics in isopropyl alcohol. This can cause the liquid to seep into the device, which can damage sensitive components. Instead, apply a small amount of isopropyl alcohol to a lint-free cloth and use it to gently wipe down the surface of the device.
Be extra careful with older devices
Avoid using isopropyl alcohol on these types of electronics
In general, it’s safe to use isopropyl alcohol on most electronics. However, there are a few exceptions. Avoid using isopropyl alcohol on these types of devices:
- LCD screens: Isopropyl alcohol can damage the polarizing layer on LCD screens. If you must clean an LCD screen with isopropyl alcohol, use a very low concentration and be sure to wipe it off completely afterwards.
- Devices with plastic or rubber parts: Isopropyl alcohol can dissolve some types of plastic and rubber. If your device has any plastic or rubber parts, avoid using isopropyl alcohol or be extra careful not to get any on those parts.
Use isopropyl alcohol in a well-ventilated area
Isopropyl alcohol fumes can be irritating, so it’s important to use isopropyl alcohol in a well-ventilated area. If possible, open a window or door to let fresh air into the room. You may also want to wear a dust mask to avoid breathing in the fumes.
Wear gloves and eye protection
When handling isopropyl alcohol, it’s important to wear gloves and eye protection in some cases. Isopropyl alcohol can cause skin irritation, so gloves will protect your hands. And because it’s a powerful solvent, isopropyl alcohol can also damage your eyes if it splashes in them. Wearing safety goggles will protect your eyes in case of an accident.
Don’t use isopropyl alcohol near flames or heat
Isopropyl alcohol is highly flammable, so it’s important to take precautions when using it. Avoid using isopropyl alcohol near flames or heat sources. Last thing you want is for your house to burn down while cleaning your computer!
Don’t use isopropyl alcohol on painted surfaces
Isopropyl alcohol can damage paint, so it’s important to be careful when using it on devices with painted surfaces. Avoid getting isopropyl alcohol on painted surfaces, as it may strip the paint. If you must use isopropyl alcohol on a painted surface, be sure to test it in an inconspicuous area first.

Water and electronics don’t mix and we explained that already!
If water does get inside the device, it can cause a short circuit and damage the sensitive electronic components. [4]
Isopropyl Alcohol Alternatives for Cleaning Electronics
While 91% isopropyl alcohol is a highly effective cleaning agent, there are several alternatives that can be used. Each has its own set of pros and cons that should be considered before making a decision.
Acetone
Now, acetone is technically not a to-go choice for electronics, but it is often used as a cleaning agent due to its powerful properties.
Acetone is great for removing grease, oil, and other tough contaminants from surfaces. It’s also effective at dissolving adhesives, which can make it useful for removing labels or tape from electronic devices.
However, you absolutely shouldn’t use it on sensitive electronic components like circuit boards or LCD screens. Acetone is very powerful and can potentially damage these delicate components. Only use it to clean the surface of your devices, not inside of them!
Just like isopropyl alcohol, acetone is flammable and should be used in a well-ventilated area.
Distilled Water
Another common cleaning agent is distilled water. Distilled water is simply water that has been purified through a distillation process. This removes any impurities or contaminants that might be present in regular tap water.
Distilled water is safe to use on all types of electronic devices and components. It’s a great choice for general cleaning and for removing fingerprints or smudges from screens.
One advantage distilled water has over isopropyl alcohol, is that it’s safe to use on LCD screens. This is because it won’t damage the delicate coating that’s present on these types of screens.
However, distilled water isn’t as effective at removing tough contaminants like grease or oil. It also doesn’t have any disinfectant properties, so it can’t be used to clean surfaces that might be harboring bacteria or viruses.
Compressed air
Compressed air is a popular choice for cleaning electronics because it’s gentle and effective. It can be used to remove dust, dirt, and other debris from hard-to-reach places. And because it’s dry, there’s no risk of moisture damage.
Compressed air is very simple to use. Just point the nozzle at the surface you want to clean and give it a blast of air. Be careful not to hold the nozzle too close to the surface, as this could damage delicate components.
Sadly, if you have a stubborn adhesive or other substance that needs to be removed, compressed air probably won’t do the trick. In this case, you’ll need to use a stronger cleaning agent. [1], [5]
