My definitive method using Squirt:

Put the Squirt bottle in a hot water bath to reduce the viscosity. Leave in for as long as it takes to wipe off the chain and/or tune in to ESPN on my basement TV.
Shift the bike to cross chain in the big-big combo and drip the Squirt onto the top of each roller just before it goes over the cassette. Silca has a video showing how the links spread and allow the lube to get in there. Back pedal a few times to set the stuff in there and run it through the gears.

If it has been a while, or has been noisy, repeat but this time dripping on the other side of the chain, cross chaining small-small.

Squirt says don't wipe off, so I don't.

Let dry overnight. Turn off TV while swearing that the whole time was just commercials and I missed the Sports Center Top Ten Plays, again.

And Importantly, before turning off the light, look back and admire how great my bike looks.
