manufacturing a salt scrub vs a sugar scrub
we may have to product a salt scrub in our tanks/kettles. Do tanks have to be grounded working with a salt scrub? I know some places will not produce a salt scrub and will happy produce a sugar scrub.

I would say no - salt’s not known for causing electrostatic discharges, and in any case, that’s only a risk when you’re handling flammable materials in the same space

maybe it’s not because of the Electrical discharge but because of the abrasion effect that the company will accept sugar scrubs but not salt ones?
as far as I know, it is harder than sugar because of the crystal structure. Steel and Salt have nearly the same Hardness on the Mohs hardness scale (normal steel around 2, Salt between 2 and 2,5) therefore if you are not using special Steel which is made harder you will scrub away your Production vessel / Homogenizer / Sierring peddles and so on. which can be very expensive in the long run

Salt also can contribute to corrosion of metals so this may be why some choose to not manufacture salt scrubs.
