However, this is no substitute for manual cleaning: For optimum performance and consistent flavor, you should clean your device regularly. The exact procedure for cleaning varies depending on the model. The general cleaning steps are simple:
Cool holder sufficiently:
Allow your IQOS holder to cool sufficiently before you start cleaning (at least 30 seconds after the last use).
Tap the holder:
Remove the cap and tap the holder gently on a smooth surface to loosen tobacco residue.
Use the cleaning tool:
Now remove the cap from the cleaning tool. Insert the cleaning tool straight into the holder until it reaches the bottom and then turn it gently.
Use a cleaning-stick:
For more thorough cleaning of your IQOS holder, use IQOS cleaning-sticks regularly, after around 20 tobacco sticks (please use carefully!) Be sure to not exert too much pressure and to not touch the heating blade.
Finally, you should also clean the inside of the cap of the IQOS.
