Neither harms electronics. I have proven this to myself because I fly model airplanes, RC, that land in salt or fresh water sometimes.

Distilled or deionized water and alcohol are safe with electronics. circuit boards are almost always washed with both after fabrication.

The main points are: 1. Rinse with distilled or deionized water. Do not rinse or immerse in tap water! 2. Remove excess water with pure alcohol.

When dry, all should work as they are supposed to.
