The Campy advice sounds pretty bizarre to me. Thanks anyway, I'll keep doing what I've been doing.

Comments:
Rowan, I've never tried synthetic, but used regular motor oil once. It was a gunk magnet. Everything that got close to my chain stuck.

JoeTown, the Forester formula also calls for paraffin, that's what the white gas is for... to dissolve the paraffin (instead of using heat and melting it). The gas evaporates, leaving the paraffin/oil mixture.

Miamijim, what's the harm in removing your chain to clean it if you've got an SRAM, or have installed a power-link (or whatever they're called)?
