Krummy K-nuckles - un gluing

[Isaac OLEG]

if the glue is a bit too,strong, a drop of vinager will soften it
enough so you harly broke a shank when popping the knucles off.

I've done it with 60% alcohol too, but the vinager is stronger (or a
mix acetic acid + alcohol, the interest could be that it may soften
tyhe vinyl glue as well if necessary - for key bushings it works with
less stain marks than wall paper remover)
