Sticker Stains?

[Flamingtoasters]

My old Mac SE, which I just finished de-yellowing, has a sticker stain. The sticker itself was from an aftermarket computer upgrades store, and the majority of it was transparent. But the text and everything opaque on it has literally been imprinted onto the surface of the case. I initially though the stain was a result of the unsheltered plastic being exposed to UV and yellowing. But it's still there after the de-yellowing and I don't know what to do next. Any ideas :?:

P.S. Oddly enough, the stain is darker than the rest of the plastic, not lighter.

Try Goo Be Gone or some other glue remover.

Adhesive will keep any whitening chemical from hitting the plastic.

If you have to use Goof Off, just carefully add one drop onto a cloth and try using the cloth. Any more of that can easily go through pretty much any plastic like a hot knife in butter. :'(

I would appreciate seeing a photo of this sticker residue.
