Fixed one once by lubricating the hog-rings that attach the mesh to the frame. Vaseline/Petroleum jelly. Well, it was already in the room.
I imagine it would make a mess of the underside of the mattress, but it was an emergency.

CRC is a penetrating oil. The trouble with penetrating oils is that they keep spreading until there's nothing left where you want the lubrication, it is all over the earth.



Husband. "What are you doing under my bed?"

Strange Man. "Just oiling your hog-rings, mate. Fixing the window next."
