Clear the Hidden Build-Up
AquaSpa Pipe Klenz is the deep system-clean step in the AquaSpa chlorine-free and bromine-free spa system, created to clean the hidden internal pipe-work where body fats, grime, scale, and organic build-up can collect over time.
Even when spa water looks fine on the surface, residue can remain inside pipe-work and associated systems, especially in warm, recirculating spa environments. AquaSpa Pipe Klenz is used before draining to help clear this hidden build-up so the system can be cleaned more thoroughly before fresh water is added.

How It Works
AquaSpa Pipe Klenz is a concentrated internal system cleaner used to break down and loosen the calcium, grime, organic build-up, and harboured body fats that can remain inside spa pipe-work and associated systems. In warm recirculating water, these residues can collect in hidden areas even after the spa has been emptied.
Used before draining, AquaSpa Pipe Klenz circulates through the internal pipe-work to help lift this build-up so it can be flushed out more effectively during the drain-and-clean process. This makes it an important part of deeper system care, especially when periodic internal cleaning is needed.
