Is this anything drastic to worry about or will a clean and grease suffice?

That does seem excessive - but obviously the frame is carbon so it's not structural - it's an alloy sleeve. I would give it a good clean and grease and see what happens. If it corrodes enough that the sleeve starts to move then the frame is probably done (uneconomical to repair) but it should be fine for now if you get all the crud out of there - and after riding in the wet probably worth draining the bike so that water doesn't sit in there.

Thanks K-dog,

I shall do exactly that then, do you think its worth putting some epoxy putty on it to prevent is getting worse or just use a heavy amount of lithium/copper grease?

thanks

I would just grease it and keep an eye on it.

LBS time get the threads cleaned out and then get some grease in there.
