If it is the 3M stuff, should come off without leaving any (not much anyway) residue. Heat it with a blow drier and peel it off. I have applied this stuff to some of my car interior, and when not happy with the first application, heated it up and removed ,then re-applied again. Left no residue (glue etc) when I did it.
The citrus spray is just a cleaning product ,can be found in most supermarkets next to the spray and wipe etc.
