I am looking for a kitchen salt grinder.
I know salt is an aggressive compound and it needs a little bit of attention when we design products.
Since most of grinders have plastic-made or stainless steel-made parts (I'm talking about grinder mechanism), and corrosion is virtually unavoidable,
As engineer, I have one (+bonus) question:
I know salt can corrode metals, is it true for plastics too?
Bonus. Concerning about health, is preferable to have metal corrosion (rust) or plastic corrosion?
