Scale neutralizing ability is a titration that measures how much the descaler solution can dissolve. The maximum time allowed for this analysis is 1 hour. Dynamic Descaler dissolves 56% more scale than our competitor.

* Dynamic Descaler is also known as Bio D’Scale in Asia and as Precision Descaler in some US states
