Hi, All,
I unhook the springs with paper clips bent so that they hook onto the springs and can be hooked onto the upper edge of the RF deck frame, maintaining tension on the springs so as to avoid them getting away from you. The clips are bent into something resembling a lower case "h."
By all means, number racks with Magic Marker so as to keep them in order if you remove all of them during, say, an RF deck overhaul. The same goes for the cans. Clean off markings with a paper towel lightly dipped in mild solvent such as paint thinner.

I learned many valuable lessons by messing up coils;
1. Paper form coils should not be oiled. The oil swells up the paper and
eventually the slug will not turn or it will tear the coil in half while
trying.
2. It is probably one of the only uses of talc in the radio. The slugs
should work free with absolutely no binding. Do not be afraid to un-spring a
slug rack and remove it for cleaning and/or inspection. Note do not lose the
little springs down inside the radio. Hemostats are your friends and a few
of us have the very old tool sets with the picks and probes for removing and
reinstalling springs (mine came from an old teletype service kit).
3. Do not remove all of the racks at the same time. Some of the slugs in the
IF racks are quite different than those in some parts of the RF deck.
4. Buy a junker RF deck for the parts.
5. Have fun, do not go into this with too much "reluctance".(pun intended)
