from personal experience: Forget Acetone and Lacquer thinner or the Citrus stuff, unless you want to spend a lot of time scrubbing. The bomb is any paint or mastic remover in gel form from your local hardware store or the big evil HD or Lwes stores. Just brush on, wait 5-10 min and scrap will metal butter knife, reapply as required. takes it down to the metal in at most 2 applications, do a whole wheel in 45 mins. The fumes are almost non-existant. a $5 can will do more wheels than you possibly need.
