I'm building a new home and I prewired my house for surround sound and the internet. This past last week the sheetrock guys came in and did my home. They hung the sheetrock and sprayed the walls. During the course I was out of town to overlook the job. Well I walked into my home and I had an instant aneurism. They sprayed all my speaker wires with the banana tips on them including all my cat5 wires that I crimped at the ends. So pretty much all my wires are caked in sheetrock spray. They really went full retard doing my home. Anyway is there any the of solvent that I can clean the tips of my speaker wires and cat5 wires without damaging them? I tried using soap and water and it was able to get alot of it off but not all of it. Especially the tips of my cat5 which I don't feel like recrimping them.
