Deoxit is awesome! Above you can see a dirty Fuse panel in my 74 Jeep (pretty basic wiring as. Compared to today’s Jeeps) it was dirty and not making good contact. I unhooked the battery, then gently cleaned her with Deoxit and a tooth brush! She’s running better now. I didn’t immediately hook back the battery just to make sure all of the cleaner had dissipated. You probably can but I’m cautious.
