I'm hoping someone can help with this. I accidentally dropped the remote for my ceiling fan into a large cup of water. The fan and light were on at the time. Although I removed it immediately, the remote is not working and I can't shut the fan or the light off. I tried changing the battery, but it didn't help. Any suggestions?

Keep the batteries out, and leave it for a couple days to dry out. You can help by using a towel to try and get as much as you can out of the inside, but leave it for a few days, then try putting the batteries back in a few, and it should work... I dropped my remote in the toilet (dont ask lol) and did that and voilà! It worked after 2 days of drying

I had a similar experience with one that was left in the rain. It still didn't work after a couple of days, so I left it on my car's dashboard in the warm sun. Voilà! The moisture evaporated, and it came back to life. Perhaps putting it on a heat register this time of year would be better.

In some cases, though, the water actually ruins the device. Cell phones are famous for that. Good luck with it!

Yeah, if you can dry it out, great, but if not you will have to purchase a replacement. They make universal remotes.

Remote for cd/micro stereo got wet going through a wash cycle. Dried it out, did not work for four weeks then tried again, got use of it for three weeks then it stopped. Changed batteries, noticed a wet type substance on the inside of keypad that is not water etc, has chip totally packed up?

Timeinhand, spray with strong spray of water can usually blast that out.

Anyone dropping Electronics in water needs to remove the Battery IMMEDIATLY(electrolosis starts immediately), If just water, drying may be all it needs.

If soda, salt water or other substances is the problem, Warm water helps rinse out the contaminants, then a good drying, When Law Enforcement Officers dropped their handhelds in salt water, and they needed back quickly, we would preheat the oven, low temperature, turn off oven, place electronics in oven while it is cooling down. Do not melt any plastics, not sure the temperature, hopefully you will not place in oven while still too hot.

Electronics are supprisingly tough.

I dissemble remotes when some buttons don't work, rinse with warm soapy water, rinse, dry on the cable/sat box, dashboard, wipe the buttons rubber pads in the back, and maybe an Eraser for the buttons contacts(copper traces).
