[Nodxa] Fw: How to loosen rusted hardware . . .

[Mary Michaelis]

We keep a bottle of the mixture on hand but Aero 
Kroil is our go-to fluid to get things 
unstuck.  A few years ago Pete N8TR found the 
gift-pack of three flavors of Kroil under the 
Christmas tree and this year he received two 
industrial-size Aero Kroils.  Stuff really works.
