3M makes a window film that blocks better than 90% of heat, and less than 10% visible light, so it doesn't look like tint, but sure looks like $$$.
Goo Gone is citrus, if you go to a carpet cleaning supply they have Citrasolv a MUCH more concentrated version, but jugs only last a couple months before going soft, its strong stuff.
Goof Off stinks.
WD40 is stoddard solvent, only issue is getting rid of the residue. PBBlaster I've heard also works along with a plastic scraper.
