Do those pictures agree with your "wavy vibrations"?
Why do you want to clean the bowden? You can take it off but be careful - it's easy to damage. If there are pieces of PLA inside, just let them go through and melt in the head.
UM1 or UM2?
On the head you have to reduce the pressure on the bowden by unscrewing/taking apart the head a little bit - to reduce the pressure. Then remove the little red or blue clip and push down on the outer ring and slide up the tube. The gray ring that holds the bowden in has 4 metal blades. If you aren't careful you will scrape the bowden and when you put it back in it won't stay in very well. Don't pull up very hard. This instructions were written for UM1 and UM2.
You might also consider reducing the xy-jerk setting, if the issue is just mechanical vibration of the whole printer during printing fast, short infill sections where the head changes direction lots in a short amount of time.

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.

If the wavy lines are caused by vibrations, you can reduce the acceleration from 5000 to 3000 and it won't affect print time much:

I've never removed the bowden on the other end.
