2004 C class bulkhead drains

[Marquisofraspberry]

What's the preferred method of cleaning the drains, I've pulled out what debris I can, is a carefully aimed hose pipe the way to go or a wire coat hanger or something else?

Compressed air is best if you have a source available. Your local garage would do this for you I imagine.

I have also used curtain wire with some success.

+1 for the curtain wire.
It’s worked well for me in the past
