Stainless Steel Surface Prep

The Objective

What are we trying to achieve?

Ensure stainless steel tanks, tables, and equipment are sterile, passivated, and visually pristine.

Improper wiping leaves streaks that harbor bacteria, or uses abrasive materials that damage the protective chromium oxide layer.

Common Challenges
