At $11 for a couple of tiny bottles, both of which you have to use together, it's another 2-3x more expensive than tape head cleaner.
For me, the bottom line is how much it will cost to clean *one* CPU/heat spreader combination.
Because I always have a Menda bottle full of high-purity alcohol on the electronics bench, I find many uses for it.
If I had to drive to Radio Shack every ounce or so to get a refill, I would doubtless not bother for most jobs.
100% is possible if you synthesize it
I'm not sure what you mean by synthesize in this context.
I mean assemble the molecules from bulk quantities of their constituent elements. :) Chemical engineering.
As my measurement data in the post I just sent hints, there are serious practical problems -- aside from the direct economic ones -- that restrict the utility of such high-purity alcohols. There's probably no point using it outside a cleanroom. Dust on the glassware will wreck the purity rating otherwise.
