I actually use AppCleaner (not the one I told you about) and EasyFind. Whatever AppCleaner leaves behind, EasyFind gets. When the App Cleaner and Uninstall mentioned service files, I was curious as to what they are and if removing them could cause a problem.
Duh! Now I get it. Service files cover a broad spectrum and to a large extent what it covers depends on the application developers personal definition. In general you should not suffer any damage from removing "service" files but just in case I would...
- Be sure I had a current Time Machine backup I could restore the "service files" from
- Keep a record of what service files were deleted from where (screenshots are handy for this)
- Never ever delete anything from the /System folder
- Check the file and path to be sure you are deleting any system files
