Customising a piano

[J Patrick Draine]

A E & list,
Hoppe's ingredients:

INGREDIENTS NAME CAS NUMBER CONCENTRATION BY % VOLUME

Severely Hydrotreated Heavy

Naphthenic Petroleum Oil 64742-52-5 >85%

Polyalpha-olefin 66070-54-0 <10%

Proprietary Additive Proprietary <10%

Possibly A E chose to use this having heard of the use of ballistol, which
has been used in Europe in lubricating action parts. It's also a component
of Mother Goose's Goose Juice.
>From Wikipedia:

*Ballistol* (meaning 'Ballistic Oil') is a mineral
oil<http://en.wikipedia.org/wiki/Mineral_oil>-based
chemical which advertises that it has many uses. It was originally intended
for cleaning, lubricating, and protecting
firearms<http://en.wikipedia.org/wiki/Firearms>.
The product originated from Germany <http://en.wikipedia.org/wiki/Germany>
 before World War 2 <http://en.wikipedia.org/wiki/World_War_2>, after the
military requested an 'all-around' oil and cleaner for their rifles and
equipment.

The chemical is a yellowish clear liquid with a consistency expected of a
light oil. However, when it comes in contact with water it
emulsifies<http://en.wikipedia.org/wiki/Emulsion>,
becoming a thick creamy white substance. It has a sweet and mildly pungent
smell similar to black licorice <http://en.wikipedia.org/wiki/Licorice>. It
is distributed in liquid and aerosol
<http://en.wikipedia.org/wiki/Aerosol> forms.
The aerosol uses butane <http://en.wikipedia.org/wiki/Butane> or
propane<http://en.wikipedia.org/wiki/Propane> as
a propellant <http://en.wikipedia.org/wiki/Propellant>.

One of its selling points is that it is not
petro-chemical<http://en.wikipedia.org/wiki/Petro-chemical> based,
and uses biodegradable ingredients. It also advertises it has no
carcinogens<http://en.wikipedia.org/wiki/Carcinogen>.
Some other similar chemicals contain petro-chemicals which can pollute the
environment if improperly handled, and can damage the 'seasoning' developed
on the bore of a black-powder gun.

As someone has already noted, WD-40 is a lubricant which was used by piano
technicians in an earlier era; it loosened things up for a while but
eventually got gummy, caused parts to freeze up, and soaked into the wood as
well -- essentially ruining everything it came into contact with. It's
appropriate for use on metal parts.
