I'd like to give soda blasting a try, however I'm a little perplexed (common these days) about the part where it brags about the anti-rusting effect soda has over sand blasting, then mentions how much more easily soda is to remove (rinse) from the substrate being blasted.
Uhm, once you rinse the soda residue from the substrate, of course using water, don't you then kinda start the oxidation process all over?
