Please follow these steps carefully to sterilise the cartridges properly:


Ensure you have gloves, isopropyl alcohol solution (70% or above) and a clean container to hold the solution.


Put on your gloves to avoid contaminating the cartridges during the sterilisation process.


Check on your cartridge; ensure the needles are in perfect condition (i.e. not bending) and remove any debris.


Pour enough alcohol solution into the container and dip the cartridge needle into a sterilisation container, then soak for a couple of minutes.


If you have alcohol solution in a spray model, you can spray it towards the needle head of the cartridge.


Once the sterilisation is complete, allow the cartridge to air dry fully before using it
