Get an old tooth brush and start with some distilled water (hell, its a Ti, you can use tap water for all I care!)
Open the case to get a better view of the rest of the board, or not!
Scrubb it and then rinse. Then, you might try some jewelery cleaner and scrub again in the battery pack area. You may just want to use Q-tips and clean the battery contact area. This is to prepare for a battery solder attachment.
Can you solder?
Buy a cheap 4.5 V phone battery pack from Radio Shack (You do have the charger, don't you?). Solder in onto the two battery terminals (Check http://www.ti59.com/ for details or information). The Ti-58 is basically a Ti-59 without a card reader and half the memory.
All of this can be for naught as the 58 could have further corrosion inside that may have ruined the traces between chips or even bad chips due to over Voltage or abuse in the past. Looks can be decieving.
