salt build up

That's possible. I would clean it away and see if it returns. If it does the there is salt creep at the joint and it will need to be attended to.

Hi Dwight

Long time no talk.

I agree clean the area and watch it closely. I could very well have been some water splash during the move that has since dried. Hope that is all it is and all is well.
