Thank you for the replies! I will try the cooking oil or vinegar to remove the rest. Jasper seemed perfectly fine last night which was a relief.
It's so easy to Skype! It's the first thing I do when I get to work. In case anyone's interested:
1. Create two Skype accounts
2. Set up your camera in front of your bird cage (make sure to set the computer to never sleep/shut down), in Skype settings under calls put answer all incoming calls automatically AND start camera
3. From your other account (at work, on your phone, wherever you are), call the account at home and it will automatically pick up and turn on the camera
I've been doing this ever since I got him, I like knowing he's ok

And of course it's fun to see what he's up to.
I also suggest setting your computer at home to start skype automatically when you turn on your computer in case there's a windows update or something that reboots your computer automatically.
