Epsom salts is magnesium sulfate.  VX-6 used to be a cadmium sulfate 
solution.  Have they changed it?  

When I was a pimple face, the local discount store sold this snake oil.  
So 
did some of the garages.  It came in a little bottle maybe 10 cm tall and 
cost a few bucks, perhaps $3 or $4, IIRC.  It was dyed red.   

As I understand it, somehow cadmium sulfate binds to the crystalline lead
sulfate that won't take part in the charging reaction, and precipitates it
out.  (No, I don't know how this works.)  This doesn't add any real 
capacity
to the battery, but it may temporarily reduce its internal resistance.

The usual "proof" that VX-6 worked: turn on your headlights until the 
battery
is dead.  Now shut them off, and go pour in your VX-6.  Wait a few 
minutes. 
Now try to start your car.  Presto!  Look at all that new energy the VX-6 
gave
your battery!   

Of course - as we all know - a "flat" lead battery left to its own devices 
for a few minutes will "regain" some charge, quite possibly enough to 
start 
an ICE. But this "proof" sure made the stuff look good, and gullible 
customers bought it.
