How It Works
Over time, cartridge filters can collect debris, oils, body fats, minerals, grime, organic build-up, and calcium scale. Regular cleaning helps remove this build-up and keep the filter in better condition as part of ongoing spa maintenance.
SpaCare Instant Filter Klenz uses a no-soak spray-on, hose-off formula to lift build-up from cartridge filters so it can be rinsed away more easily with fresh water. This helps make cartridge filter cleaning quicker and more convenient.

Frequently Asked Questions
Why does my cartridge filter still look dirty after cleaning?
Some filters carry heavier build-up than others, especially when oils, body fats, minerals, and scale have been sitting in the pleats for some time. In these cases, a second application may be needed to achieve a cleaner result.
What if my filter foams while I rinse it?
Foaming during rinsing can happen as the loosened build-up and cleaner are flushed out of the cartridge. Continue rinsing thoroughly with fresh water until the foaming stops.
Why is regular cartridge filter cleaning worth doing even if the spa water still looks clear?
A filter can hold oils, debris, and other build-up even when the spa water still looks fine. Keeping the cartridge clean helps make ongoing spa care easier and supports cleaner overall filtration.
Is this only for deep cleaning, or can it be used for regular upkeep?
It can be used for regular upkeep as part of weekly spa maintenance, not just when the filter is heavily soiled.
