Have rough cut cedar board and bat siding. Have been thinkng that corn blasting would be the way to go on removing the BEHR #13 that has black mildew on it. Suggestions on removal and if corn blasting is the way to go, what grit pressures etc. should I use?

Go with the corn blasting. You want to keep the wood as dry as possible.
