The Nexus Citric Acid Cleaning Cartridge is an easy-to-use solution to hard water scaling within any Nexus water ionizer.

Nexus Citric Acid Cleaning Cartridge Directions:

1. Remove the acidic hose and plug-up that port.
2. Stretch the spout [flexible-hose] out over the sink - slightly downward, but at the end curl it up to where the tip of it is above the height of the water ionizer.
3. Remove filter and insert the Nexus Citric Acid Cleaning Cartridge into the filter port.
4. Run the water ionizer on filtered-water-mode at a slow trickle until it starts to come out of the tip of the spout.
5. Let it sit for about an hour or so.
6. Re-position the spout to point downward and run the filtered-water mode at normal speed to rinse out the machine.
7. Remove the empty Citric Acid Cleaning Cartridge and return the filter to its normal position.
8. Return the acidic hose to its normal position.
9. Rinse the machine once more for about a minute [in filtered-water mode].
