I would basically say the same as Roger.
If the windows are really minging then you might have to wash them with your aplicator sleeve, including as much of the frames as you can, use a damp scrim to dwtail the top three edges of each pane of glass and the frame and then use a cut down squeegee on them.
You'll have to fart around with a lot of detailing afterwards though.
But it is worth the effort on a first time clean.
On subsequent cleans use a spayer to mist the glass (and I agree with Roger that Tesco's own brand one is just about the best AND the CHEAPEST out there) and buff clean with either microfibre or scrim.
I personally prefer Microfibre, but others like to stick with scrim.

Oh, and if you are inexperienced, just remember that georgian work will take you 3 times as long per window to do...minimum

I've just read Jeff's reply
I've done the same thing as he describes (nor with beer mats though, they don't come even close to being as effective as scrim or microfibre, doesn't look as professional either
)
But you do a time and motion study (and I have..often) and squeegeeing georgian windows in whatever manner you may choose is slower than either wet scrim-dry scrim or mist and buff with sprayer and microfibre.
