In several videos, I've seen them spray those dreaded electrical connectors. I'm assuming it's to help disconnect them. I've searched and can't find any specific electrical connector spray. I found some old forum that talked about using soapy water. However, those videos seem to be spraying some sort of aerosol spray.
Does anyone know of such a spray? What do you use?
Is soapy water really a good idea? Water conducts, couldn't that cause a short? Or rust?
