Ok.
Bought some of the windex with vinegar and am going to use it tomorrow at the range.
Cayugad, I found a supply of castor oil at a pharmacy here and bought 12 bottles (2 oz). Raised eyebrows at the checkout.

I have made 4 batches of the hard lube and poured them into foil mini loaf pans from the grocery store. They are stored in the beer fridge in the garage for future use. One batch of the hard lube fills the mini loaf pan just right.
Have you used this lube to pan lube?
I have a little hotplate in the garage and am going to melt it down to try it.
