how to clean up config files?

[kitts]

I have been using linux for a little over a year now with KDE. I have 
changed distros/hardware and reinstalled a few times but have always 
retained my home folder.

During all this i may have messed up several config files.For example i have 
plenty of programs listed under the "lost and found" entry in KMenu. Most 
of these are not installed currently and some and redundant.

Is there a clean solution to clean up the mess? One solution might be to 
create a new user and copy over all files from there to here and delete 
whats excess but i don't like the solution very much.

What are my options?
