Hey, I apologize if this has been covered before, I know rust has been talked about, but I'm not sure if my issue has been discussed. Breaking down a polished Juliet frame and all the screws are rusted. Not a problem, I have a Wiha T6 so the screws came out easy peezy. How do I clean the threads on the frame, WD 40? There looks to be a lot of rust left down there on the ear stem and orbital threads. I have replacement screws ready to go, just want to clean the frame super well so I don't get any rust on/ruin the new screws!
