Paint (not lacquer)  thinner is pretty benign stuff--safe for most 
plastics.  When I remove labels, I first examine the label.  Some 
manufacturer's labels are shiny coated stock--if that's the case, I 
scuff the surface of the label with a copper scouring pad 
(nonferrous; doesn't "shed" like Scotchbrite or sandpaper).  This 
allows whatever you use to soak through the label.

I brush the paint thinner on with an acid brush only allowing it to 
wet the label.   After a 10-30 minute soak, the label should come 
right off.  Wipe off any excess thinner with a soft rag; eventually 
any remaining solvent will evaporate.  

This works for me for the "sticky" adhesive labels, but 
manufacturer's labels might be a different story. Maybe Isopropanol 
or methanol might be worth a try on those.
