the alcohol is just a carrier so ratios can vary. As cheap as it is to make I would rather have it a bit more concentrated and have zero chance of a case sticking. I did go back and empty what was left of the open bottle of alcohol into the spray bottle just to get rid of it so it is now 4 to 1. On the net you can find ratios from 1 -3 to 1-10 I decided to err on the conservative side. After the alcohol evaps it gives the cases a slick feel, not really greasy or sticky at all.
I have seen these recipes many time through the years , I think this thread is the one that spurred me into making a batch.
