Canola Oil Spray eliminates SQUEAKS in doors,

I live in a rather old house, it is around 110 years old. Very structurally sound, you know... When they KNEW how to build them right.

Everything is original, the doors, the paneling, the floors, etc...
This means the OLD hinges too.
We did replace the skeleton key locks with NEW skeleton key locks.
Due to someone getting locked in their room... and I digress.

If you have a door that is just SCREECHING like a banshee,
Canola Oil Spray will remedy that.
Just Spray each hinge, open and close the door several times!
NO MORE SQUEAK...

I did this because I had NOTHING else to oil the door with. 
So I grabbed what oil I had available.
It's been 8 weeks and still no squeaking!
VIOLA!!!
