Or lighter fluid, as used in 'Zippo' lighters. It'll take off the residue very quickly, and clean the part. Evaporation takes care of any possible problem where paint might be affected, and a quick wipe-over with a soft cloth will clean-up things and finish the job.
It's been used in the photo and graphics industry for many, many years, for cleaning the glass on scanners, copy board glass on process cameras etc, and is probably used more in this area than for its original purpose !
But test on a similar part first, as some transparent parts, from some manufacturers, may use a different type of 'plastic', which may 'cloud'.
Alternatively, given that the painted areas have been sealed with the relevant clear coat, then a quick wipe, and then polish, with 'T-Cut', or a similar car-body colour restorer/polish, will not only remove the residue, but will also give a crystal-clear sparkle to the transparency, and remove any scratches.
