I take a long small control-wiring flat screwdriver to carefully insert into the front of the grip and slide back under it. Then I put the long red straw of the Tri-Flow in next to the screwdriver shaft as far back into the grip as I can and squirt in the oil. If you can do this 2-3 more times around the diameter of the grip you can pretty much get most of the grip lubricated. Then it is a simple matter to carefully work and twist the grip until it breaks free and just slides off.
Soak the oily grip in a pan o blue Dawn detergent and the Tri-Flow washes right off and you are left with a good undamaged vintage grip that is ready to be re-installed later.
MUCH better to do this with alcohol (ethanol or iso-propanol, doesn't matter). In fact, by far the simplest solution is to use a syringe with a long enough needle to inject a bit of alcohol between the grip and the handlebar. Once you've removed the grip, the alcohol will quickly evaporate.
