Does isopropyl alcohol conduct electricity?
Content
Isopropyl alcohol is used to clean surfaces and as a solvent. Some people believe that it can also conduct electricity. This is true?
Before explaining in detail, here is a short answer:
Yes Isopropyl alcohol makes conducts electricity, but its conductivity is so low that it can be considered non-conductive.. Entrance to Madame Tussauds generally safe to use for cleaning electrical components and contacts subject to certain precautions.

Does isopropyl alcohol conduct electricity?
For general purposes, it can be assumed that alcohol does not conduct electricity.
It does not have the free electrons found in metals, allowing electricity to flow easily. However, isopropyl alcohol is usually a mixture of about 70% alcohol and 30% water. The water component is more electrically conductive. The higher concentration of isopropyl alcohol is typically 90% alcohol and 10% water, so it is relatively less electrically conductive.
Technical explanation
No material has an electrical conductivity of absolute zero, i.e. there is nothing that does not conduct electricity at all.
Materials differ only in the degree of electrical conductivity. For most intents and purposes, those with very low conductivity, as in the case of isopropyl alcohol (C3H7OH), are considered non-conductive. Their conductivity matters only when the value is not negligible, as at the micro level.
Typically, isopropyl alcohol has an electrical conductivity of about 6 µS m.-1 (6 microsiemens per meter). For comparison, the electrical conductivity of metals is several million cm.-1.
Why the conductivity of isopropyl alcohol matters
Isopropyl alcohol is used in several ways. For example, it is used:
- For cleaning electronic components, connectors and boards.
- For removing components that have had thermal paste on them, such as CPUs/GPUs. (1)
- As a cleaner in DIY projects.
- For disinfection during make-up application and for hair removal.
As you can see, isopropyl alcohol is mostly useful as a cleaner or disinfectant.
It can easily kill germs, which is why it is used to wipe surfaces. It is also the main component of medical alcohol. However, it is best used where you need to scrape off grease or remove a sticky substance. An alcohol-based cleaner with 70% isopropyl alcohol works well (and is safer than using a cleaner with a higher concentration of alcohol).
Otherwise, a regular non-alcohol cleaner may suffice. Hot water and soap are easier to get, safer, and cheaper for general cleaning.
Be careful! Isopropyl alcohol is highly flammable. Do not apply too much in places where it matters, i.e. in places exposed to heat.
It's important,chicken is used to clean electronics, that's where its electric conductivity is the most important. Since it is negligible, it can be safely used to clean all types of electrical components and contacts. It also evaporates quickly at room temperature in air.
Be careful! When cleaning an electrical board, component or contact, they must not be connected to a power source. Otherwise, a short circuit may occur. Turn it off before applying isopropyl alcohol, allowing enough time for it to evaporate. (2)
Additional Tips for Safe Cleaning with Isopropyl Alcohol
Here are a few more important precautions when using isopropyl alcohol:
- You only need to apply a small amount of isopropyl alcohol. Use a soft cloth, cotton swab, or clean cloth.
- Applying large amounts indoors can be harmful to health. Use isopropyl alcohol only in a well-ventilated area.
- Isopropyl alcohol is only suitable for external use. It can be fatal if consumed.
If you are concerned about electrical conductivity, you can use an alternative to isopropyl alcohol cleaning, such as compressed air or cleaning wipes.
Summing up
Technically, isopropyl alcohol conducts electricity, but its degree of conductivity is negligible and can usually be neglected. Its conductivity is mainly a concern when cleaning electronics. It is generally safe to use for this purpose if some precautions are taken.
First, to clean an electrical board, component, or connection, turn off the device, apply some isopropyl alcohol and let it evaporate before using the device. If you are concerned about its conductivity, you can use safer and cheaper alternatives. However, isopropyl alcohol is better for thorough cleaning, such as when you need to remove grease or other debris from electrical components.
