[CAUT] VS Profelt a Spirlock or aluminum cauls,

[Chris Solliday]

I've never used the plastic but I routinely use the aluminum cauls with VS Profelt.
Is alcohol a solvent for aluminum?

  Pianotek Supply's "technical article" on the usage of VS Profelt is very short. I have a set of keys that I wish to size/lube with this stuff, but my supply of cauls are are aluminum and polyethylene (Spurlock). The brief tech article states "Soaking the key bushings with VS Profelt and using a brass caul ...". Anyone know if the aluminum & polyethylene ones are also AOK? As some have stated that the mystery juice has alcohol content, I don't want to find that I'm melting plastic or leaching aluminum into the bushings.
  So, is everyone using brass cauls with this stuff, or are the other cauls just as good?
