Cast Iron Nightmare??
I was given a nice old 10" cast iron skillet from the 1950's. Only problem is the former owner sprayed it with WD40 in his garage so she wouldn't rust. Any chance of bringing it back?

Media blasting will do little more than clean the surface of the pan. I would not waste the media to do it.
WD40 has a flash point, I am sure that a charcoal fire or the oven will easily exceed the flash point of WD40--that will burn away the oil. Time is on your side. The oil if any in the pores will work its way out of the pan to the surface and there may be some ash. Wash the ash away and do the heating/cleaning process again.
Fire is a wonderful cleaner.
If its a particularly rusty piece I will have at it with a wire brush or scotch brite pad on a die grinder. It can look very stark.
I like old cast iron and have a number of pieces, when I get an old piece of cast iron I use the above process and when done cleaning, they are clean and ready for seasoning.
