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.
Key Features & Benefits
Deep cleans internal pipe-work
Targets the hidden areas of spas, hot tubs, and spa baths where residue can remain inside the system.
Helps remove body fats and organic build-up
Works on the residues that can accumulate through normal spa use and remain trapped in internal pipe-work.
Helps address calcium and grime
Formulated to help loosen unwanted internal build-up that can collect over time inside the spa system.
Supports more thorough system cleaning
Helps prepare internal pipe-work and associated system areas for a deeper clean during drain-and-clean maintenance.
Works where build-up is not always visible
Designed for the hidden internal parts of the spa system, not just the surfaces you can see.
Supports a cleaner overall spa system
Helps clear hidden residue so the spa can be restarted with a fresher internal system.

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.
How to Use
- Ensure the water level is at least 50mm above the jets.
- Add AquaSpa Pipe Klenz to the spa water at the required dose.
- Run the pump for the required circulation period as directed on the label.
- Scoop away any foam residue if present.
- Drain the spa completely.
- Wipe the spa clean and refill with fresh water before restarting the AquaSpa program.
Dosage & Coverage
- Dosage: 250mL per 1,000 litres of spa water
Important Usage Information
- Use AquaSpa Pipe Klenz before draining the spa or hot tub.
- We recommend using AquaSpa Pipe Klenz at least once every 3 months.
- Because this product contains acidic compounds, the system should be fully flushed before using the spa again.
- Follow the full label directions carefully when using this product.
Spas should generally be drained every 3–6 months, and more often with high usage. AquaSpa Pipe Klenz is the deep system-clean step in the AquaSpa routine and does not replace sanitising, shock treatment, balancing, filter cleaning, or regular water replacement where required.
