Used the electrolysis method and had it sit over night on my porch, only had to scrape a few small spots to get it clean when I pulled it out of the water.
Washed it down with some soap and water, dried it off on the stove top and wiped it down with cooking spray.
Next step is to season it in the oven tomorrow while the wifes at work.

I have another Wagner #8 i need to clean as well.
