I'm a big fan of LA's Awesome Cleaner. Works well on stubborn adhesive and gunk of all kinds. It's cheap if you have a Dollar General around. Look for the clear bottle with yellow stuff in it and a homemade looking label.
And yes, I use Maxima Chain Guard and PJ1 Black.......the Black only because I couldn't remember what one I liked and I think now that it is the Blue since the Blue seems to clean the crud off while spraying and not goop up so bad.
