OK, soap chemists, what is cause for rust building up on my Martin de Candre shave soap tin?
3 yrs ago, I repotted some soap from the MdC original glass jar, to a smaller 2-oz flat tin with tin screw top lid. Good for travel.
But the rims in both the bottom and top are now rusting.
No similar issue with any other soap in similar tins.
Any explanation??
