Label mark on sunvisor

[Slartibardfast1]

I've been doing some detailing and one of the areas I'm having a problem with is a "stain" on the sunvisor (the previous owner probably removed a label and the adhesive mark is still there).

I've tried a number of remedies (unsuccessfully):
Goo Gone
Sticky Stuff Remover
Vanish
Dr Beckmann stain remover
Upholstery cleaner

Any more suggestions please?

Many thanks

Direct sunlight cures a lot of uneven colour marks. Mind you, good luck getting any at the moment.

It might be easier to replace the sicker, it’s one regarding the passenger airbag and how to disable for child seats I believe

The original label was on the reverse side of the visor so I've removed it and replaced to the front side where it was originally. There is a "stain" now on the reverse side (no probs as not normally on show) which means that it is from the adhesive and not from UV, as this side is never exposed to the sun.
