How does alcohol dry things out?


Isopropyl alcohol is a liquid. How is it used to pull other liquids out of electronics? What properties make it happen? Won’t it trigger liquid detection strips in, say, a cellphone?

Alcohol and water are miscible (they can mix). If you place electronics in alcohol, it will reach all the tiny corners where water is hiding and mix with it, “diluting” the water.

Then the alcohol evaporates, so the remaining water is now spread out over such a large volume that it evaporates quickly as well.

The detection strips rely on a hydration reaction with water. They probably won’t work with alcohol.
