[Boatanchors] What is "No Clean" solder?

[Phil]

My present roll of Alpha 63/37 is down to it's last wrap on the roll, so 
I had to order some solder today (Leaded solder ONLY please).  As I had 
to order some other stuff from Mouser anyway (I find their on-line 
search format clumsy, but am getting used to it), I ordered from them.

I wanted to order two rolls, one .031 thin and one thicker for PL-259's 
etc, as leaded solder is getting more difficult to find and more dear in 
price.  I figured two pounds would last me quite a long time.

Well, I found the .031 Activated Rosin core OK, but the ONLY thicker 
Kester I found was .062 "No Clean" at nearly half again the price (about 
$45 vs. $31 per pound).  So I opted for two rolls of the .031, figuring 
it's the same amount of solder, just have to use a longer length on 
large connections.  It should last me quite a while, unless I go 
"building crazy" (have been lately).

But what is "no clean" rosin core solder and what makes it so dear in 
price?  Surely it can't do that much better a job. . .
