Handlebar adhesive stains alum. handlebars?

This 40 year old bike of mine probably has had this black cotton tape for it's entire life. I take it off and I am left with dark marks from the adhesive -or some type of surface etching that it has caused. I tried wet sanding and nothin. WD-40 and acetone did nothing. What the hell is this and what do I use to remove it, if possible? Not sure I want to sand too deeply on old handlebars.
I've ordered Cinelli cork -which I might shellac- but I want the cork only to just above the brakes so lots of shiny metal is bare. The left side of the bar is affected the most while the right is quite clear where I need it to be.
Got anything?

Sad to say Aluminum is porous so the stain may be deep in the
metal itself. Try "Brasso" or another metal polish to see is that
will bleach the stain out. Failing that you're stuck with a need for
a new plan on how to cover the metal.

Best of luck.

Pretty much what I had figured. Brasso/simichrome and various cleaners won't work. I guess I'm either living with it or covering it up entirely. Not going to sand deep whether or not it's safe to do so.

Thanks for the reply.

Try using those white "Mr. Clean" sponges, they really clean deep into the surface. Try them with or without a solvent like goo gone, isopropyl alcohol or lighter fluid (naptha).
