Key Takeaways:
- Corrosion occurs when stainless steel’s oxide layer is compromised in GMP areas.
- Rouge traps residues and microbes, making cleaning and sanitizing more difficult.
- The FDA sees corrosion in product-contact systems as a contamination risk.
- A proactive, risk-based strategy is better than reactive maintenance for corrosion.
- Maintenance should be guided by scientific data and risk, not just visual checks.
