Thanks for all your ideas. I have tried degreaser and paint thinner to no avail.
The inside of the mug is glazed, and the thinner did not take anything off. There is some gunk on the outside, too, but for now I am concentrating on the inside so I can drink something out of the mug (getting thirsty).
I will try Bar-Keepers friend (I've kind of been wanting to get that stuff anyway) and Goo-Gone.
Here is what the gunk looks like:
I think whatever it is might respond well to some abrasive cleaning. I'm thinking the Bar-Keepers friend has a shot here.

Looks like hard water stains (commonly called 'tide lines', made when a previous owner has kept a flower or plant in tap water in it). Have you tried the CLR? You should be able to just put some on a paper towel and wipe them away.

OK, I might try Coke/Pepsi first (least chance of damage to the mug). Then Naval Jelly...then CLR.

OK, the results are in.
First, I tried Coke. I got a glass bottle (the kind from Mexico with no corn syrup)--the third ingredient was phosporic acid. I soaked the mug in this Coke for 4 days. It got some of it off.
Then I went to get Naval Jelly--but a little bottle of the stuff was $6. Next to it was Barkeeper's Friend for $2. I will have a lot more future use for Barkeeper's Friend, so I got that. It took the rest of the stain off in two washing/scrubbings. And I've already used it to clean a steel flask I have.
So thank you all for your help. I know a lot more about cleaning vintage tiki mugs now.
