[3.2 CAB]

It is true that baking soda is a "base" chemical as opposed to an acid which is an "acetic" chemical. But, if doing the powder blasting with the sodium bicarbonate materials, once the blast work is finished, the piece or pieces need to be flushed with a lot of water and maybe a small dilution of vinegar to balance the two chemical out, and become neutral, then flush with more clean, to get any final residue from the nooks and crannies, then air dry the parts so there is no water left standing on them. To be totally honest, I have never used and boxed type laundry soap in my gun kits, it might work... then it my very well suck. Good luck with what ever way you decide to go with!! Tony.
