Whatever method you use, first test the cleaning/removal material in an inconspicuous part of the surface the label is stuck on the be sure it will not damage that surface.
If the label on the plastic has been wet, or the article has been stored where it was hot or humid, it will be more difficult to remove.
1. Dampen a small piece of cloth, or the end of a swab stick (cotton twisted on the end of a wooden match or orange stick). Dip cotton end in dry cleaning fluid.
2. Allow the fluid to remain on the label only long enough to allow the label to be rubbed off. Wipe away excess fluid immediately, and wash article in sudsy water and dry. (DO NOT ALLOW FLUID TO REMAIN ON THE PLASTIC SURFACE VERY LONG, AS IT WILL DULL THE FINISH OF THE PLASTIC.)
