content: Quote from: Kean on April 20, 2025, 12:15:17 amOur gear in production in the underwater towed array factory used to get this sort of grime. I believe it came from the oil (Isopar M) we used in the product and then our gruggy fingers just ground all the grim into it and it somehow binds with the rubber coated knobs.Also happened to the plastic knob,s they they were easier to clean.

content: QuoteThat reminds me of my second job out of University - IT support at a local ISP. One day one of our regular clients came in with a computer wrapped in a trash bag. I could see a pool of ick at the bottom."It got dropped in a vat of used machining oil. Give us a call when it's fixed."It did not get fixed. It got taken out to the parking lot and sprayed with a garden hose for half an hour. Patient did not survive.

content: I have a couple of DMMs that get used in the field, so they encounter all kinds of grime - oil, dirt, penguin guano, etc.When working at the bench with the better gear I do try to keep things clean. Anything coming from the metal workshop or laser cutter gets cleaned before going to the electronics benches.I've also worked on some oil filled gear for submersion, but that got added during final assembly, and testing after that point would not generally involve probing it with the scope.And like many electronics technicians, I've worked on my share of devices that got dropped into water or the toilet.

I just went through finding a replacement for the BNC on my 54831M, which is absolutely unobtanium. No equivalent size/shape unless you want to make something custom. I ended up lucking out and finding someone with a dead aquisition board that sent me one of his BNC's
