first time I ve built kit in years and put trailing edge in wrong. I got it removed by using debonder the question is do I have to do anything to the balsa wood before I can reapply.. clean with anything?

The debonder will evaporate rather quickly. Take a break, grab a drink, and by the time you come back, it'll be ready to go.

Do what bryris said. only thing I would add is take a paper towel and wipe the wood clean from all the gunk from the debonder and the CA that was dissolved. then you'll be ready to put it back on.
