Isoproprl Alcohol Use for Cleaning Electronics

Why you should use 90% Isopropyl Alcohol instead of 70% Isopropyl Alcohol for cleaning usb ports and other electronics

Isopropyl Alcohol is one of the most common household supplies used for cleaning electronics and computer components. It’s great for removing dust, grease and grime from surfaces. But did you know that there are two different types of Isopropyl Alcohol to choose from when cleaning your electronics? The two types are 70% and 90% Isopropyl Alcohol. Although both can be effective for cleaning, the higher concentration of alcohol in 90% Isopropyl Alcohol makes it more efficient at killing bacteria and germs. In this article, we will explore why 90% Isopropyl Alcohol is a better choice than its 70% counterpart when it comes to cleaning usb ports and other electronics.

What is Isopropyl Alcohol?

Isopropyl alcohol, also known as rubbing alcohol, is a multi-purpose cleaning product that can be used on a variety of surfaces. It’s a powerful cleaning agent that can remove dirt, grime, and residue from surfaces quickly and easily. Isopropyl alcohol is also an effective disinfectant and can kill bacteria and viruses on surfaces. When used correctly, isopropyl alcohol is a safe and effective way to clean usb ports and other electronics.

The Different Grades of Isopropyl Alcohol

When choosing isopropyl alcohol for cleaning electronics, it’s important to choose the right grade. There are three different grades of isopropyl alcohol: rubbing alcohol, technical-grade alcohol, and pharmaceutical-grade alcohol.

Rubbing alcohol is the least pure form of isopropyl alcohol. It contains impurities that can damage electronic components. Technical-grade alcohol is a little purer, but it still contains some impurities. Pharmaceutical-grade alcohol is the purest form of isopropyl alcohol and is the best choice for cleaning electronics.

Which Grade of Isopropyl Alcohol should you use for cleaning usb ports and other electronics?

When cleaning usb ports and other electronic devices, it is important to use the correct grade of Isopropyl Alcohol. The two most common grades of Isopropyl Alcohol are 91% and 99%.

91% Isopropyl Alcohol is the minimum concentration that should be used for cleaning electrical devices. This concentration is effective at removing dirt, dust, and grime from surfaces. It can also be used to clean sensitive electronic components without damaging them.

99% Isopropyl Alcohol is a more powerful cleaning solution than 91% Isopropyl Alcohol. It can be used to clean stubborn dirt, grease, and grime from surfaces. It is also effective at removing fingerprints and smudges from glass and plastic surfaces. This higher concentration of alcohol can also be used to disinfect surfaces.

How to clean usb ports and other electronics with 90% Isopropyl Alcohol

If you’re looking for a powerful cleaning solution for your usb ports and other electronics, then you should definitely consider using 90% isopropyl alcohol. This type of alcohol is much more effective at cleaning than regular rubbing alcohol, and it can also help to prevent corrosion on your electronic devices.

To clean usb ports and other electronics with 90% isopropyl alcohol, simply apply a small amount of the liquid to a cotton swab or cloth and wipe down the surface of your device. You’ll want to be sure to avoid getting any moisture inside the port or on any sensitive components, but otherwise this cleaning method is safe for most electronics.

Once you’re finished cleaning, be sure to allow the device to dry completely before using it again. If you’re concerned about possible residue left behind by the alcohol, you can always rinse the surface with water afterwards. However, in most cases there will be no need to do this as the alcohol will evaporate completely on its own.


In conclusion, it’s important to remember that 90% Isopropyl Alcohol is the best choice for cleaning usb ports and other electronics. It has a lower water content, making it less likely to cause damage to delicate components in these devices. Additionally, with its higher alcohol concentration, it works faster and more effectively than 70% Isopropyl Alcohol for tackling stubborn dirt and grime stuck in hard-to-reach areas. For the most reliable results on your electronic device cleanings, make sure you reach for 90% Isopropyl Alcohol every time!
