For my crawl space mold problem I've heard the professional cleanup

clean up areas that don't need the wood replaced.

Do I need to get a "Soda Blaster" or can I just get a Harbor Freight
pressurized abrasive blaster and fill it with baking soda? Just
wondering
how much difference there is between an "Abrasive Blaster" and a "Soda
Blaster"?

You will find that baking soda is far far too fine.

They sell different grades for blasting, they claim it will remove paint
or powder coat but not rust. Soda blasting is also recommended for mold
removal from wood and cleaning up fire and smoke damaged wood. Soda
blasting is supposed to have started with the work on the Statue of
Liberty.

It works well, but takes time, and I was using a large pot and a 175 CFM
compressor. It also leaves an alkaline mess.
