What Is Passivation Of Stainless Steel?

What Is Dry Ice Blasting?

Also known as cryogenic blasting, this cleaning uses compressed frozen carbon dioxide, or dry ice, and sublimates under high pressure on a rusted surface. After, a high-pressure power jet blasts the ice, at a temperature of -79° C, onto your contaminated stainless steel surface. Because the stainless steel surface is warm, it creates a “thermo shock,” loosening the rust while the dry ice evaporates.

How To Remove Rust From An Iron Skillet?

Removing from an iron skillet requires a mixture of white vinegar and equal parts water. Pour the mixture in a plastic bucket and let your skillet soak in it for eight hours. After, wash it off and clean cloth.
