Proteck

[Richard Brekne]

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.
