I used the veggie oil and acetone mix (but with around 30-40 percent
acetone), as outlined in the Drexel U lab report. It worked well on a badly
rusted 3/4 bolt at the base of my crankup. I did my mix in a glass jar with
a lid that would seal. Actually a large size baby food jar I got from the
granddaughter. Didn't need a large amount. The Drexel U lab report notes the
use of paraffin to keep the mixtures homogenized but does not note what
specific paraffin and amount to use; anyone knowledgeable about this?
Would using ATF instead of veggie oil also benefit from paraffin to preclude
separation of the two liquids? I have not used the ATF/acetone solution.
Wonder also if the acetone level has to be at the 50% level to work well.
Good idea on the acid flux use brushes, didn't think about that!!!!!
Being a few hundred feet from the ocean I learned, after moving here and
getting everything up, that regular hardware, including much of the
galvanized stuff, just wouldn't hack it. Now I always replace when necessary
with good SS hardware from the local fishing fleet supplier with generous
use of their recommended CorrosionBlock compound on all threads and mating
surfaces such as tubing.
But, I have an old TH7, partially disassembled, that has been sitting out
back on sawhorses since moving here. A couple of the elements tubing have
become stuck together such that I can't pull or twist them apart, probably
corroded or the like from the local salt air. What is the best penetrating
solution to use on aluminum? Would the above mix work without harming the
aluminum? Have not tried anything yet and before I do suggestions would be
welcome.

Julio, Don't forget the caveat about not breathing a lot of acetone
fumes. Harbor Freight and other outlets sell "acid" brushes, small
metal handled brushes used with acid flux in plumbing soldering. These
are good as applicators. An eye dropper or spoon or whatever depending
on the specific circumstances can be used. Mix in ATF with the half a
can of acetone you have in the previously mentioned glass jar and use
the jar to soak small parts if need be.
There are plastics that are impervious to acetone and ATF but in general
I avoid long term contact between acetone and plastics because it is
difficult to be sure exactly what plastic something is made of. The sure
fire way to find out which plastic will work is to put acetone in the
container, seal it up tightly waiting for a good long time to see what
happens.
Those acid brushes are good for applying No-Alox or thread dope and
other messy stuff.
