can i use 91 isopropyl alcohol to clean electronics

Yes, 91% isopropyl alcohol can be effectively used to clean electronics. It's particularly good for removing residue, it evaporates quickly, and leaves nearly zero oil traces compared to lower percentages. However, it's important to turn off and unplug the electronic device before cleaning to avoid any potential risk.

As long as the electronic device is powered off and given enough time to dry completely before being powered back on, there should be no potential for damage. However, you must avoid making the electronics soaking wet. Just use a little on a swab and carefully clean.

You can apply the isopropyl alcohol with a lint-free cloth, or for tighter spots, a small brush or even a Q-tip can work. Just make sure to rub gently to avoid harm to the components. Also, don't forget to wear gloves to protect your skin.
