What you do is remove the chain from your bike, there is a Park Tools sledge and crowbar especially for this, you will notice that there are some roller things linked together with some flat bits. You don't have to bother with the flat bits but if you use your Park Tools tool kit expertly you should be able to dismantle the roller parts from the flat buts and set them out on your bench. Once you have them all set out with the bit that rolls on one side and the bit that it rolls into on the other side apply Vaseline to all parts and put it back together.
This is the method my Uncle in Broad moor used for years but I never tried it myself, let me know how you get on.
