Remove adhesive residue from the Playstation. How best?

For whatever reason, I stuck felt "feet" under my Playstation.

Then I noticed a stupid idea. The felt feet were from Ikea and the adhesive from the things is so penetrating that I can't get it anymore.

Oil, soap, soak tried everything. Does anyone else have an insider tip on how to get these glue residues off?

Maybe with a hair dryer or carefully with a ceramic hob scraper, you can't get sticker remover from the hardware store. Is there e.g. From Mellerud:

There are adhesive removers in every hardware store. Would start with a soft one, otherwise you also take off the paint…
