75% alcohol (usually 75% isopropyl or ethyl alcohol) is widely used for cleaning and disinfecting electronics. A common question is whether it conducts electricity, which is important for safe use.
1. Conductivity of 75% Alcohol
Pure alcohol is an insulator and does not conduct electricity. However, 75% alcohol contains 25% water, and dissolved minerals and ions in the water give it some conductivity. Although this conductivity is low, it can still pose a short-circuit risk for sensitive electronic components.
2. Safety Tips
-
Avoid letting large amounts of liquid pool or seep into electronic circuits.
-
Use alcohol-prewetted cleanroom wipes to minimize liquid volume and reduce risk.
-
Ensure the device is completely dry after cleaning to prevent electrical issues caused by residual moisture.
3. Conclusion
75% alcohol solution has low but present conductivity, so caution is needed when cleaning electronics. Proper handling and thorough drying are key to safe use.
