Deep Clean the Pipe-Work You Cannot See
Iluka Purge is a concentrated internal pipe-work cleaner for spa pools, hot tubs and spa baths. It effectively purges hidden pipe-work and associated systems where calcium, grime, organic build-up and body fats can collect over time.
By cleansing the internal system, Purge helps remove harboured residues, including bio-film, from areas that normal surface cleaning cannot reach. It gives your spa a more thorough system clean as part of periodic water replacement and deep maintenance.

The Iluka Sea-Mineral Spa Experience
Iluka is an Aboriginal word meaning “near the sea”, and the feeling of being in a sea-like environment is at the heart of the range. Iluka Sea Minerals by Lo-Chlor brings together mineral comfort, water clarity and simple spa care to help create a more natural, luxurious and enjoyable spa experience.
Inspired by the calming feeling of being near the sea, Iluka transforms spa care into something softer, fresher and more rewarding — less like maintenance, and more like a calming ritual.

Frequently Asked Questions
Why clean spa pipe-work if the water looks clear?
Clear water does not always mean the internal system is clean. Body fats, grime, calcium and bio-film can build up inside hidden pipe-work and associated systems where normal surface cleaning cannot reach.
Why should Purge be used before draining?
Purge works through the existing spa water to loosen and flush residues from the internal pipe-work. After the treatment has run, the spa is drained so the loosened build-up can be removed from the system.
What signs can suggest the pipe-work needs cleaning?
Foaming, dull-looking water, recurring odours, residue around jets or water that becomes difficult to maintain can all suggest build-up inside the system. A pipe-work clean helps remove hidden residues that may be contributing to these issues.
Is Purge the same as a surface cleaner?
No. Purge is used to clean the internal pipe-work and associated systems. It is not a wipe-on surface cleaner, although deposits released during treatment should be rinsed away from around the shell and jets after draining.
Should I clean the filter at the same time?
Yes. The filter cartridge should be removed before treatment, and filter care should be completed as part of the drain-and-clean process. This helps prevent old residue from being carried back into freshly refilled water.
