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 :)
