Kerosene will be the cheapest since many gas stations sell it by the gallon and WD-40 and Finish Line's degreaser are by far the most expensive way to accomplish the same thing.
I've been to a lot of gas stations around the country and I haven't seen any of them selling kerosene. They might have back in the 60s and 70s, although I don't recall seeing it even then. Most "gas stations" now are food stores with gas pumps outside and I definitely don't recall seeing kerosene on the shelves of my local 7-11.

Big Box home stores do sell lots of nonpolar solvents which are listed by the various names I gave above. Some even sell kerosene although, in my experience, kerosene is more expensive than mineral spirits.

It might be a function of where you live. I agree that many stations don't seem to have kerosene anymore, but in/around farm country, I find most non "branded" stations have a kerosene pump around the back.

The oven cleaner has been addressed above. As others have said you can use long cotton swabs like these to get to harder to reach places. Soak the tip in mineral spirits and go at it.

However, if the hardened grease is inside the shell, there is no real reason to remove it. It's not hurting anything and won't interfere with the function of the hub. In actuality, hardened grease in the races isn't all that bad either. Fresh grease will work as a cleaning agent as well. Pack the bearings, ride it for a while and the hardened grease will dissolve in the new grease. Next time you repack the bearings, residue will be gone.
