Leaking 'door breathers'

Its annoying when I wash my car and the next morning there is sticky residue down the bottom side skirts etc.
Tried cleaning the bottom runs of the door where it is seeping from but its extremely sticky.
I know its a lubricant of some type, but has been leaking for weeks...
Anyone experience anything similar? Ideas how to stop/clean effectively.

hopefully it stops before then.My BMW F30 did a similar thing and dripped from the bonnet at the front and down the headlights (stained one of them) - had it replaced with no explanation and the lock mechanism on the boot constantly leaked the same sort of stuff.. Previously to that, I hadn't experienced a car thats done that before.
