Hi All,

A bit trivial but very common problem...
I got a free 203BA i had to remove from a tower. It has been there for
years.
All parts are OK except that i can't dismantle some elements. Certain
tube junctions are corroded despite some tape protection, and the
elements are like soldered.

Is there a safe way to remove the aluminium oxide so i can disassemble
the elements for transportation ?

I've been told that letting petroleum seep between the elements would
help. But that can take days or ... weeks...

I'm sure, you all had this problem one day and that someone found a
"good" solution.

Thanks for any comments,
