So I accidentally put an open water bottle in my bag while my tablet was in there, LCD was unfortunately flooded, but I ordered a replacement screen and it arrived today. Though opening up the tablet I found water droplets throughout, so I removed every part meticulously to put in rice or something and noted any current corrosion I had to remove with a q tip.
My question is this. As soon as I opened it up I noticed the water very quickly evaporating. I actually can’t see any more now. Anyone who does mobile device repairs, what do you think? Could I skip the deep-dry? I looked at all the components and none of them have any parts that could have trapped water that I missed and I don’t really look forward to cleaning the entire thing of starch ( though I do just have silica beads but let’s stay on topic)
Am I right to feel confident about the dryness of the components? Let me know!

You ordered a replacement screen and wait for it to arrive before even opening the device? Why?
Removing corrosion means it will be harder to see where the damage is.
Next time:
- Open as soon as ASAP possible!
- Disconnect battery.
- Let it dry. No rice or dog shit or whatever. Proper desiccant or nothing.
- Reconnect battery and test.
- Win or start debugging.
- Fix it
- Remove corrosion when everything works only now - unless you expect it to cause the issue, then at least document it before cleaning.
Making a few assumptions here,
-
I hadn’t thought about it, but the device worked and the screen clearly had liquid trapped between the layers. So once I saw that I turned it off, and ordered a new screen, because believe it or not, desiccant doesn’t do jack for a waterlogged LCD.

I said “noted” corrosion, not that I went ahead and removed it
-
The motherboard can be cleaned with a generous amount of isopropyl alcohol. It cleans slightly corroded areas, displaces water, is not a good conductor of electricity and evaporates easily.
Don’t put any rice near it. Use the silica bags.
Alright, and what about the not seeing any moisture?
You can’t see under the chips, my guy. Put it in a warm place or with silica bags as suggested and let it dry for safety.
Alright I won’t take the risk then, I’ll take a look at it with the video microscope to look for corrosion then toss the components in a silica bag
Rice is bad because it doesnt actually absorb much moisture and can cause mold growth
Better to put it in front of a fan to add air circulation and maybe warm it a bit (i.e. near ish to a heater but not on it)
I didn’t know this, thank you for the info
