Scraping or using solvent (generally) seems like a rather bad idea...
Why??
I just used a touch of white spirit, but obviously afterwards you would want to thoroughly wash both the tank and your hands before going near any valves/regs.
It only takes a tiny bit of solvent on a clean cloth, and the residues just dissolves, but it does gum up the rag pretty quickly as it wipes off.
Plus the fumes on some of the stronger ones can be, erm, interesting
