SpaCare System Klenz Internal Pipe-Work Cleaner 500mL – Spa Chemical (DG)

Deep Cleaning for Internal Spa Pipe-Work

SpaCare System Klenz is a concentrated cleaner for internal pipe-work in spa pools, hot tubs, and spa baths, formulated to remove calcium, grime, and organic build-up from within the system.

It helps clean hidden internal areas where harboured body fats, including bio-film, can remain as part of normal spa use, supporting a deeper level of system maintenance beyond visible surface cleaning.

Used as part of scheduled spa care, System Klenz helps keep internal pipe-work and associated systems cleaner during periodic maintenance and water change routines.

How It Works

SpaCare System Klenz circulates through the internal pipe-work and associated systems of the spa or hot tub during treatment.

As it moves through the system, it helps loosen calcium, grime, organic build-up, harboured body fats, and bio-film from inside the pipe-work and associated areas, so they can be removed during draining and rinsing.
