Great video, using a plastic safe contact cleaner and following up with isopropyl alcohol is the way to go. Isopropyl alcohol is widely used in avionics. After cleaning we are required to perform a no go test. You have great attention to detail.
Dave could you make a video showing how you de pin connectors. Thats something I really struggle with and would be useful to check some female pins for serious water corrosion.
Top job there Dave, look as good as new after your magic , as always attention to detail, was Poppy going to look down the back of the sofa fir your change that's fallen out of your pockets after a wee bit of dancing 👍😉
I noticed that descaler doese an excellent job in removing oxidation. However you do have to clean very well afterwards because is highly electric conductive.
White vinegar works extremely well. Follow it up with baking soda in isopropyl alcohol to neutralize the acid from the vinegar. And finish the job with Deoxit.
White vinegar is not recommended as will tarnish the electroplated contacts, will attack plastics, dissolve rubber grommets and melt insulation. The guy in the video is showing what he uses and shows the results without vinegar. Deoxit is a brand of electrical contact cleaner similar to what is shown in the video
