Welcome back Ajn. I think the X1 has a shield against such instances. If you fancy changing to a premium brand sometime I’m told the X1 is a proper BMW. Unlike the Volvo and owners you won’t find any flies on them.
The handling and pure exuberance of the gearbox should see off any unwelcome pests post-haste!
Also think a bucket of warm soapy water applied 5 minutes before a wipe over will do nicely.
