I got a Apple cube here as part of a larger haul, at some point someone
placed a bit of tape on the clear polycarbonate case, the tape is long
gone but the yellow glue remains.
Am unsure about the hardness of it, if I could use sugar cubes to
rub it off, anyone knows a scratch free way to get it off ?
Regards

Have you tried Goo Gone?

A chemical engineer friend in the adhesives business told me years ago that WD-40 is a
good solvent to use for adhesives stuck to plastic. It's unlikely to hurt the plastic
but it will soften the glue. It's not fast but it does work. As always, check on a
hidden part of the case to make sure the particular plastic doesn't object to the
stuff you're using.

I?d be scared to try Goo Gone on a Apple Cube case. IIRC, it?s not exactly normal
plastic.
As Paul points out, try whatever is used on a spot that will be out of view.
This is a great question, it applies not just to the Cube, but to any Apple system of that
vintage.

Plastics preservation is a huge topic, the art museums have alot of
experience there, identifying that you have is the first hurdel.
The earlier models I got
Macintosh plus
IIvi
lc 475
Quadra 660AV
do seems to hold up alot better than the later models
9500/150
7600/120
lc 630
the plastic especialy the typed used inside the cases is brittle like the
SGI skins

I assume you've already attempted to throw the usual household stuff at it
as if it was a phone or TV. If not, dig out the glass cleaner and microfibre
cloths and get onto that.
In addition to the plausible suggestion elsethread of WD-40, I'd also give
it a gentle waft of a hairdryer (or heat gun set suitably-low) to try and
melt the glue without melting the plastic, and then it may be more amenable
to wiping-off.
Brasso, T-Cut, or similar come in useful if you manage to scratch it anyway.
Test your technique on some matching scrap plastic first before moving on to
the case. You say "polycarbonate" but Wikipedia says "acrylic", and
these
have quite different mechanical properties so you should verify which
plastic the case is actually made from. Maybe the resin code will tell you,
but I suspect it'll just say 7 (other).
If all else fails, style it out by sticking your own label over it :)

... and then you snipped the following paragraph where I pointed out the
case may be acrylic rather than polycarbonate, which is kind of important
given this:
One other possibility is ethanol. But be sure to test
that first, because
it WILL damage plexiglas ("lucite"). That's about the only plastic it
hurts, though.
Plexiglas and Lucite are brand names for acrylic.

From all I have been dig up on it, its polycarbonat
that was used for the
outer casing, going on that it seems wd-40 would be a no go.
I ended up tested with ethanol on the buttom feets, seing no ill effect after some
time, I tested it on the glue and I started to see miscolouring of the
papertowle, the glue was comming off.
If all else fails, style it out by sticking your own
label over it :)
:) good advice also if attempts had made it worse
Thanks to all for advices
