Yes, I was probably the one who mentioned heptane before. I have used it quite a bit. Works really well for removing the feet of HP41's. Place a drop on a small Swiss Army Knife blade, slide it under the foot (try to get under the double sided adhesive, not between the foot and the adhesive). Also works great lifting the corners of classic HP machine labels. I do the same as with the HP41 feet, but use a razor blade. They are thinner than the knife blade, but be very careful not to cut the label though.
Superlube is a teflon based grease mad by the company "Permatex". It can be found just about anywhere in the US (hardware stores, auto parts stores, etc). It is a translucent white substance. I think just about any teflon grease would work fine. Also the Radio Shack Lube Gel should be available all over the world.
Another recomended calculator chemical is white gas (cigarette lighter fluid, camping stove gas). It removes adhesive residue, grime, etc from cases and display windows with ease. Don't get either the heptane or white gas on the keyboard backgrounds though. They can leave "water marks".
