This is the thing. I have a hot air popcorn popper,. very old but has always worked great. Since it doesn't require oil, I have always just wiped it out with a damp cloth. Over a month ago, lacking regular popcorn, I tried to pop microwave popcorn in it, sadly, the kettle corn variety. BIG MISTAKE. The non removable cup inside the popper was coated with the thick flavoring grease. I tried to wipe it out, but it didn't work, so I washed the popper, not immersing the machine, but running water into the cup part. A little wanter came out the bottom as well. I did not get the cord wet. I shook it really well and left it to dry. This was over a month ago, and I am afraid to plug it in again! I have not used it since then. Please let me know if you think getting water inside it made it unsafe to use?
