Many folks recommend mild detergent/water solutions; use with moistened (not dripping!) toothbrush or I prefer (lots of) Q-tips.

If the machine was not used for a long period, the keyboard will likely work better as you use it more. While it's possible there was some kind of spill inside (e.g. soda or coffee) you can usually tell as there is sticky crud around the keys.

Once you have removed the serious dirt, you can also use small amounts of Armor All using a soft cloth; it cleans the plastic and leaves a nice finish.

The key is to just take your time cleaning it slowly and lovingly. Plan to spend an hour on it. It may not take that long, but the results will be much better than if you try to do it in 5 minutes.

OK! I was planning on using damp (not dripping) watercolor brushes, to see how far that takes me.
