The way I understand it "noclean" solder doesn't need to be cleaned off. I've never tried it though, someone correct me if I'm wrong.
Um, I guess that holds true EXCEPT for when using no clean
I have never used that stuff so I can't really say what the drawbacks are.
I used the 60/40 rosin Kester and cleaned the whole board with techspray and had no problems with cold solder joints or flux bridges. Does the no clean work well?

Does it have to be cleaned? My 60/40 says it is non-conductive. I've never had problems, but I haven't done a large and sensative project like this before either...

60/40 is just the mix which does not really say anything about the flux material so the stuff I use has the normal rosin core that needs to be cleaned with a solvent. The organic stuff can be cleaned off with methanol but the commercial flux cleaners will make a mess of it.

Ok, so my kester 60/40 probably has a type of rosin core that is safe to leave on the circuit board, since it is "not conductive"... if anyone's experience differs, let me know please.

I've been slow to get a flux remover so my whole project has stalled. Can you believe Radio Shack doesn't sell flux remover?
Save yourself a lot of trouble. DON'T use a flux remover (at first) - you'll just end up spreading flux all over the board. Been there done that, no thanks.
You can easily chip off excess flux using a non metallic scraper such that it can't scrape through the board laquer (something like a wooden lolly stick or plastic guitar plectrum, shaped if needed). Wait a little while after soldering so that the flux sets hard, it will then flake away with a little sideways pressure. You can remove 95% of the flux this way, then use flux remover if you want it absolutely spotless - not necessary in my opinion.
