I was flying my drone when it hit a tree and it fell on a pool of water that had green things in it (maybe algae idk). We immediately took it out and removed the batteries. It seems it sat there for about 5 seconds. We dried it by shaking it and left it in the sun for some time. Then we used the dryer to dry everything inside. Then I found online that you should immerse it with alcohol to avoid corrosion. So I bought a 70% isopropyl alcohol as 99.99% wasn't available, and poured it over the drone before drying it again with the dryer. After that I left it in a bag of rice for about 24 hours. I tested it with the battery that was affected and it said battery error and also barometer fault or something. I switched the battery and everything worked fine this time. After I took it out, I notice seeing water inside (like small droplets) only to be surprised that they were hard. Now I don't know what to do.
Questions: Shall I take apart the drone to bettery dry it? Did corrosion already set in, was it right using the alcohol? Is 70% ok? Do I have to soak it in an alcoholic bath instead of just pouring alcohol in it? Was the rice a good move? What did those hard water mean? How long should I wait before flying it again? It seems like there was still water inside, what should I do? Do I take it off and redry it again?
Thnx to whoever answers this
