Cappuccino poured into the air system

Hello!

This is my first post here, I am researching for a friend of mine who isn't so mechanically savvy, it's not my car but I will likely be doing the repair.

Yesterday, a cappuccino was left balancing on the dashboard, fell over, and nearly the entire thing poured directly down into the main defrosting air vent that is beneath the windshield. Oh man, tragic and horrible but also hilarious that the whole coffee poured directly down the vent. Everything functions fine but now there is a coffee down there that will likely mold during these 35°+ days in Berlin.

2014 Berlingo (diesel)

1. Is it difficult to get to the disassemble the dashboard to get to the air hoses and clean them out?
2. Is it possible to partially disassemble the dashboard to access the vents without making the project too crazy?
3. Does anyone have a link to a detailed repair manual?
4. Is there an air filter deep in the air system that likely needs to be replaced? Perhaps there is a "catch" in the venting system like in a sink to capture things that could fall down the dashboard.
5. Is it worth it?

I wish we could just pour a gallon on water down the drain to chase it but that's likely not an option.


I'm sure it won't be too big of a hassle, but it's difficult to get too involved with big projects that could take days or weeks when you have to work in the Berlin streets without facilities or securities to leave the project open.

Thanks for your help and input!

Peace!
