Well Carl, it depends, and depends largely on what flux system you are 
trying to clean.  If I was constrained to a single solvent for universal 
cleaning, I would pick Kyzen Cybersolv 141R solvent.  It has worked well 
on both the leaded and lead-free flux systems that we have tried.  Also 
works well as a general cleaner.  Kyzen also tends to support their 
products very well.  You can get more info here:

As a second choice, you might consider Chemtronics Heavy Duty Flux-Off. It 
also works well, but is more designed for flux removal than general 
cleaning.

Not sure what the relative costs of these are, but they should be widely 
available.

Subject:        [TN] General purpose spray solvent question
Sent by:        TechNet <[log in to unmask]>



History:  I grew up with a can of GC Electronics "Big Bath"
solvent/cleaner within easy reach, using it for flux removal, adhesive
clean-up, and a wide variety of solvent related tasks.  Each of the
monster 22 oz. cans would last for several years of my minimal usage
patterns.  The last can I bought cost $18 and is almost empty.  The
local store no longer stocks this item.  Looking in the catalogs, I see
that there are a variety of blends going by the name of "Big Bath", with
a variety of solvents and propellants, with prices up to $45!  Maybe
it's time to change my old habits.

Question for the group:  What is your favorite/best/recommended spray
solvent for general clean-up?

Bonus Question:  What characteristics make it your favorite?

Thanks,
Carl
