Detergent – Hard Water Compatibility (High Ca/Mg)

This research examines formula performance in hard water conditions to reduce soap scum and maintain cleaning power. Objective: improve chelation and prevent redeposition.

Method: Wash tests were run with elevated Ca/Mg hardness using identical stain sets. Residue on fabric and washer drum was assessed.

Conclusion: Visible improvement with chelator addition; still mild redeposition at extreme hardness. Increase builder system.
