Can I fix water damaged 3DS?

"The best chance you have to fix this is to take it apart and clean it. I use 91% Isopropyl Alcohol and a toothbrush. I also have a small spray bottle that I use to spray on the motherboard then scrub it gently with a toothbrush. You want to remove any corrosion that has taken place. This will also help to prevent further corrosion.

The first thing that needs to be cleaned is the motherboard. After you clean it you need to let it dry for a while. I put mine on the window sill and let them dry in the sun for a couple hours. After it's dry, re install it and see what happens. This will give you a better idea of what else may need to be done.

Doing all of this may or may not help. I have not had a lot of success cleaning water damaged 3DS motherboards, but I have fixed some that way. Since yours still turns on you have a better chance of fixing it using this method.

I hope this helps. Let me know if you have any other questions or need further help."

this also happened to me :( idk how to fix my 3ds, the touch screen isn’t working properly and the buttons aren’t either.

I was drinking water and the cup fell while I was playing on my 3DS so what I did was put my 3DS in a towel and left it for a couple days and yeah I cried like a baby for 2 hours straight3 days later I put it on and everything works fine I just got really lucky

Mine was in the sane bag as a water bottle I was told it would not open it can go but then goes off fully charged

once my sister droped her phone in the pool then we put it in rice then we waited a couple minutes then there was rice inside the phone but we took it out it started working try putting it in rice for a couple minutes or so....

put in rice inside the 3ds and give it maybe a week.
