[CAUT] VS Profelt a Spirlock or aluminum cauls,

[Chris Solliday]

Patrick, a cursory search leads me to the conclusion that alcohol inhibits chlorine corrosion of aluminum. So if there isn't too much chlorine in the water (and there is not in VS PRofelt) you shouldn't have a problem. The alcohol might even help but I wouldn't drink that stuff even on a holiday.

    Patrick:

     

    I suspect the reason he specifies brass cauls is because that's what Pianotek sells.  Shaff's are aluminum and Bills are polyethylene so naturally he refers to cauls as brass cauls.  I can't imagine that the chemical is strong enough to damage either of the other choices or it would hurt guide rail pins.

    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?
