[CAUT] Proteck

[Jim Busby]

Ric,

Years ago we spoke with a Protek rep and this (below) is basically what we were told as well. "Prolube" does not contain the "Cleaner" in the CLP yet has their proprietary formula (which Steinway likes to use, btw). It is the "C" (Cleaner) that has been in question. As far as the lubricant goes a chemist friend told us he "thought" it was a Teflon substance suspended in a polymer. The problem is when techs simply say "I used Protek", because this "C" ingredient may be something to avoid. Prolube, on the other hand, doesn't seem to be controversial.

Also, the company rep told us to use "Prolube" mainly when applying it to metals as it bonds better, and the "CLP" to the cloth, felt, etc. This way the "C" cleans the metal or surfaces that it comes into contact with. (The "C" doesn't bond to metals)

Of course, you could simply use my friend Joes "Goosejuice" and life as we know it would be better :>0


Regards,
Jim

Hi Joe

In response to your experiment suggestion, which seemed to point in the
direction that you suspected there was some danger of Protek causing
verdigris I would post this quote from a web side I just bumped into
looking for info on the stuff.  I have no idea whether the below
statement is entirely true... but I was under the impression that Protek
was a polymer based product.

Still looking for more info on Proteks effect on wood.

    Protek CLP is a cleaner, lubricant and protectant made from
    polymers. This product removes verdigris (the green crud) and
    protects against future build-up by coating the center pin and
    sealing the felt from moisture thus preventing oxidation. Unlike
    silicone, Protek will not run, dry out or become ineffective. Since
    Protek will not harm wood, plastic, metal or the piano finish, it is
    excellent for damper guide rail bushings, underlever lubrication,
    front and balance rail pins, capstan screws and squeaky knuckles.
    Widely used, very effective product.
