In GMP facilities producing biologics and mammalian cell culture APIs, pH buffers like phosphate, acetate, and citrate are everywhere—used for media prep, purification, and product formulation.
But when these buffers contact stainless steel carts, work surfaces, or transport trays, they often leave behind invisible residues that quickly lead to rust, staining, and surface corrosion.
⚠️ Why Buffers = Stainless Steel Trouble
Even in trace amounts, buffer residues:
- Create localized pH imbalances on stainless steel
- Accelerate corrosion and pitting, especially in humid or steam-rich areas
- Leave behind stains that fail visual inspections
- Often resist removal with standard mopping or alcohol wipes
Most SOPs fail to fully remove these residues, and repeated exposure adds up—leading to early cart replacement, audit observations, and higher maintenance costs.
The Sahara Remediation Process – Restore Stainless Steel Without Harsh Chemicals
Foamtec’s Sahara Remediation Process was designed to quickly and safely remove rust and buffer-related corrosion using cleanroom-certified tools—no acids, no passivation baths, and no downtime.
The 3-Step System:
- Diamond ScrubPADS
- Cleanroom-compatible abrasive pads using fine diamond particles
- Gently polish out stains and surface rust without damaging steel grain or finish
- UltraSOLV Sponge Wipers
- Non-shedding, polyurethane foam wipers absorb and lift corrosion particles
- Compatible with DI water or 70% IPA, no residue left behind
- MiraWIPE Final Pass
- High-purity microfiber wiper ensures a streak-free, inspection-ready finish
- Removes any remaining film or fine particles for full compliance
Why It Works:
- Requires no additional SOPs or special chemistries
- Uses only validated cleanroom tools and standard solvents
- Fast, effective, and ideal for routine maintenance or pre-audit cleanup
💡 Pro Tip: Add Sahara Remediation to Your Cleaning Program Before Rust Becomes a Replacement
