I recently cleaned an Alphax #4 using Ronsonol lighter fluid.
Prior to cleaning, it was only good on T or B, with all timed
speeds running very slow.  After a good soak and drying out,
all the speeds were nominal.  I did oil the ends of the gear
shafts in the timing section only, using a light machine oil
applied with the tip of the tiniest jeweler's screwdriver I
have.  Probably about 1/100th of a drop of oil per shaft
doing it that way. I'm happy to report that it works GREAT.
