Pitch Raising to A440.......Or Not?

Hi Patrick,
Where are you located?
I know that strings that do not render across the bearing points will tear.
Due to rust mostly, but also to other forms of crud.
A few years back there was a major forest fire in my area and the smoke from
the fire coated the tuning pins and strings (everything else for that matter
<G> )
The tuning hammer almost felt glued to the pins.
Lowering the string a tad before raising to pitch did not seem to help that
much to keep from tearing the strings.
I found it necessary to use oil on the bearing point at the pressure bar.
At first I used Three in One oil Sewing machine oil , but found that while
it worked it had a tendency to get on the bass windings and the smell was
not what I liked.
In the process of searching for a product to use for this purpose
Goose Juice was developed!
I apply it above the pressure bar, and let a drop run down, catching any
excess with a rag. Once dried  the juice does not run further but still
lubricates. There is no silicon in this product.
I have also been using the Juice on centerpins.
At Reno several techs recieved the Juice.
In my own testing I have found to work as well as or better than the other
product used for centerpin lubrication.
