What are people using to clean boards with these days?  I've been using 
electronic grade isopropyl alcohol on boards I repair (solder is 
old-school Kester 245 SN63/PB37) and it sure takes a lot of IPA and 
patience to get a board clean. Same if you use it on "new construction".

Then I read someone is using MEK, but have never tried that:

Now Ian mentions ethanol.

I tried the MG Chemicals Flux Remover and I thought that was worse (more 
wasteful and expensive) than IPA. And sometimes left a white residue. 
It's mainly flux cleaning I'm after.
