Share 'removing tubular glue from sidewalls'

So I glued up my first set of tubulars. Now I need to know how to remove excess glue from the sidewall of my Dugasts? I thought I had stretched the tires enough, but getting the last part of the tire on the rim caused a little sloppiness. I can scrape it off, but I wonder if that does more harm than a solvent? I've heard WD-40 and mineral spirits, but I'd like to hear from someone with experience…
