De Gluing question

[RobSm]

Hi.
I have just been entertaining myself removing a fretboard from a neck with heat vinegar and a putty knife...with a view to re-using both.

I've yet to completely clean up the gluing surfaces ready for the next iteration.

Having got all the titebond residue off the surfaces and lightly sanding etc etc do I need to neutralise the vinegar residue with soapy water or baking soda - or anything?

Where's the end point?

(I don't do this a lot)

Thanks,
Rob.
