It is best to clean the nozzle's outside after every print, so that no black residu builds up. I usually do this immediately as soon as the print finishes: just wipe it with a paper cloth, when still hot. But you can do it later too, after warming up the nozzle a bit.
Wiping the nozzle with silicon oil prior to starting a print also reduces build-up of residu for some materials (PLA), but less with others (PET), in my experience.
Reducing temperature and making sure you have no overextrusion may also help.
I second the cleaning the nozzles after every print in the highest order. Both nozzles for me because the other nozzle may pick up stuff. Also, some of the AA core type materials are hydroscopic and will sizzle and crackle like PVA. So, I just hit them each time a print is finished.
In addition to what I said about the temp. drop, keep in mind that the idea is to drop it low enough to reduce the carbon build-up, but still allow flow. Different material manufacturers have different qualities.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
