This will make this hole in the wall air tight stop the hot and cold air drafts and keep the moisture away from the cold hence stopping the condensation.
Green stuff on electrical plug.

Anytime copper corrodes it gives off a green film.
Wd 40 will clean and replace the moisture on the wires and in the box.
Moisture has corroded the copper.
1 of 2 go to page.
The green substance is a combination of copper oxide and plasticiser which is conductive.
Replace the outlets with air tight electrical boxes or at least put gaskets under the face plates and anti draft plugs into the unused outlets.
Electrical wires are usually made from copper and as such prone to oxidation.
Thanks mate your a diamond ive just left a post on the other green goo thread how what can this stuff do to you.
Spray with wd 40 and wipe it down.
Apparently the copper wires in the plug are corroding.
Or replace it they are not expensive.
Therefore whenever this green substance is found at socket outlets etc.
The outlet spray it then blow it out and you will be good to go.
I was walking down the hall at work and noticed some green stains on the receptacles at work.
This is a 24 year old 10 color set that has been sitting in a closet for years.
If connected to a battery the subsequent corrosion can take the form of acid leakage.
The green liquid is definitely coming out of both prongs on the plug only when current is passing through it.
The electrical wires will appear to have a white or greenish powder coating on them and they will lose their conductive properties.
