Correct What Cleaning Cannot
When leather becomes unstable after cleaning, it needs correction—not more cleaning.
✨ What Acidifier 2.0 Does
Acidifier 2.0 corrects alkaline overexposure, restoring the leather’s natural response and preparing it for proper rebalancing and restoration.
2-LAYER EXPLANATION
Core:
Corrects pH imbalance caused by alkaline exposure.
Deeper:
When leather is exposed to high-pH cleaners or residues, its fiber structure can denature—leading to tackiness, drag, and instability.
Acidifier 2.0 restores the proper acidic environment, reversing these effects and allowing the leather to function normally again.
SYSTEM FLOW (ADVANCED CASE)
Cleaning → Rinse 3.0 → (if needed) Acidifier 2.0 → Rinse 4.0 → Hydrator → Fatliquor
Used only when Rinse 3.0 is not sufficient
WHEN TO USE ACIDIFIER 2.0
✔ leather feels tacky or sticky after cleaning
✔ draggy or unnatural surface feel
✔ exposure to alkaline cleaners or soap
✔ imbalance that persists after Rinse 3.0
⚠️ WHEN NOT TO USE
❌ routine cleaning
❌ as a replacement for Rinse 3.0
❌ without signs of imbalance
This is a conditional corrective step
IMPORTANT DISTINCTION
Rinse 3.0:
Residue removal + baseline stabilization
Acidifier 2.0:
Corrects imbalance when stabilization is not enough
Rinse 4.0:
Rebalances leather after correction
SYSTEM PRINCIPLE
Start with Rinse.
Correct with Acidifier.
Rebalance with Rinse 4.0.
HOW TO USE
- Complete cleaning and apply Rinse 3.0
- Evaluate leather condition
- If tacky or unstable, apply Acidifier 2.0
- Follow with Rinse 4.0 to rebalance
- Proceed to Hydrator 3.3 → Fatliquor 5.0

CORE MESSAGE
Correct before you continue.
