Optimizing Electropolished Stainless Steel Cleaning in GMP Environments: The Sahara+ System

by | Mar 28, 2024

Maintaining Surface Integrity During Effective Decontamination

Electropolished stainless steel (EP) is chosen for GMP facilities due to its superior cleanability and corrosion resistance. However, ensuring effective decontamination without compromising the delicate surface finish presents a significant engineering challenge. Disinfectant residues, if not thoroughly removed, can lead to:

  • Corrosion Initiation: Certain disinfectants contain components that can trigger corrosion on EPSS over time, compromising structural integrity and potentially introducing contaminants.
  • Surface Staining: Residual disinfectants can leave unsightly stains, impacting visual cleanliness and potentially indicating insufficient cleaning, leading to hidden contamination risks.

Limitations of Traditional Cleaning Methods:

Conventional cleanroom wipes often lack the scrubbing power required to effectively remove hardened disinfectant residues. While harsh scrubbing methods might seem like a solution, they can introduce microscopic scratches onto the EPSS surface. These scratches become breeding grounds for future contamination and compromise the inherent corrosion resistance of the steel.

The Sahara+ System: Engineered for Effective and Gentle Cleaning

Foamtec’s Sahara+ system offers a unique approach to cleaning EPSS equipment in GMP environments. This innovative system prioritizes effective residue removal while safeguarding the delicate surface:

  • Sahara Foam Wiper: High-Performance Cleaning with Low Contact Pressure—The Sahara wiper’s high-density, non-abrasive foam design is the core of the system. This material conforms precisely to the contours of the EPSS, ensuring deep cleaning in even intricate areas. The Sahara wiper effectively loosens and removes hardened residues using only water or 70% isopropyl alcohol (IPA). This minimizes the need for harsh chemicals, significantly simplifying validation processes for GMP compliance.
  • MiraWIPE Microfiber Wipes: The Final Polish—After cleaning with the Sahara wiper, MiraWIPE microfiber wipes capture and eliminate any remaining loosened contaminants and residual cleaning solution. These ultra-absorbent wipes are optimized for cleanroom environments, leaving the EPSS surface in pristine condition, virtually indistinguishable from new.

The Sahara+ System: Benefits for GMP Engineers

  • Preserve Equipment Longevity: By eliminating the need for harsh scrubbing methods, the Sahara+ system protects the critical mirror finish of EPSS, extending the lifespan of valuable equipment and minimizing the risk of corrosion initiation.
  • Streamlined Validation Processes: The effectiveness of the Sahara wiper with just water or 70% IPA reduces the number of cleaning chemicals required, simplifying validation processes for GMP compliance.
  • Enhanced Contamination Control: The Sahara+ system’s superior cleaning power removes even stubborn residues, minimizing potential harboring sites for contaminants and ensuring a sterile environment.
  • Reduced Operating Costs: The reusable components of the Sahara+ system minimize waste generation and labor costs associated with traditional cleaning methods.

The Sahara+ system is an engineered solution for maintaining the performance and longevity of your electropolished stainless steel equipment while simplifying validation processes in your GMP facility.
