We are in the process of renovating our house and I ran CAT6 cable to an area with plans to put a network switch there. I now find that the drywall people did not try and protect the connectors and they are caked in the stuff. Yes. I know I should have covered them... What will dissolve the mud? Anything? I would like to avoid cutting the connectors off and re-doing as they were factory cables.
Let's get to the root of the problem. You mudded and it kind of looked like this.

Pros use this...
Yes you simply wad up a bunch of newspaper and stuff the hell out of each box. It should be sticking out. The guy mudding can do whatever he wants. You keep it in there during sanding too. At the last stage of sanding, pull it and then use a knife/saw (I used a utility knife) to cut out any extra pieces which is usually not much or just a sliver here and there.
For things that get mud on them I usually just try to pick the pieces out or rub them between finger to break apart. If that does work a small tap with a hammer. After it breaks apart clean it with a wet rag... it can air dry.
But the entire issue is solved with less the 50 cents of left over newspaper.
