Is 50 Percent Isopropyl Alcohol Safe for Cleaning Electronics?
Use the strength your device maker names. Apple says to gently wipe the hard, nonporous surfaces of its products with a 70 percent isopropyl alcohol wipe, and not to use bleach, hydrogen peroxide, aerosol sprays or abrasives, or to let moisture into any opening or submerge the device. We found no manufacturer guidance for 50 percent. Switch the device off, unplug it and let it dry fully, because isopropyl alcohol is flammable.

What strength is safe for electronics?
Manufacturers give their own rules, so check yours. Apple’s current cleaning guide says you may gently wipe the hard, nonporous surfaces (display, keyboard and other exterior parts) with a 70 percent isopropyl alcohol wipe. It does not advise it for Apple Vision Pro. We found no maker guidance that names 50 percent.
What Apple says not to do
- Do not use products containing bleach or hydrogen peroxide.
- Do not use aerosol sprays, bleaches or abrasives.
- Do not get moisture into any openings.
- Do not submerge the product in any cleaning agent.
Safe habits
- Power off and unplug first (our advice).
- Use a wipe or a lightly dampened soft cloth; never pour or spray into ports.
- Let it dry fully before switching on. NIOSH classes isopropyl alcohol as a flammable liquid with a flash point of 53°F (12°C).
Mixing a stronger bottle down
If you only have 91% or 99%, the dilution calculator gives a 70% mix. For general disinfecting the CDC names 60% to 90% as the best range.
Can you use rubbing alcohol to clean electronics?
Only if the maker allows it. Apple’s guide says you may gently wipe the hard, nonporous surfaces of most products with a 70 percent isopropyl alcohol wipe, and for a laptop or iMac screen it describes a cloth moistened with a 70 percent isopropyl alcohol solution for stubborn smudges. Apple does not use the words “rubbing alcohol”, and we found no official guidance for other brands, so check your own maker’s page.
Can you use ethanol to clean electronics?
Apple names a 75 percent ethyl alcohol wipe as an option next to the isopropyl wipe. It does not say which is better, so we cannot rank isopropyl against ethanol from an official source. Either way, use a wipe or lightly dampened cloth, keep moisture out of openings, and never submerge the device.
Can isopropyl alcohol damage electronics?
It can if used wrongly. Apple warns against bleach and hydrogen peroxide, against moisture in openings, and against abrasive rubbing: the oil-repellent coating on an iPad screen wears off with normal use, and abrasive rubbing diminishes it further and might scratch the screen. Apple also says its cleaning products must not be used on Apple Vision Pro. For other devices, follow the maker’s cleaning page.
