Back in the day I must have cleaned many hundreds of N Type connectors, the biggest issue at the observatory was actually PP (Pigeon Poop - 60' dishes were ideal nesting sites!) However soap/water/brush worked fine for that!
The connectors that were more exposed to the elements were sealed with tape and we used a solvent to get that goop off (Trich in those days but IPA would probably be a safer alternative today!) and no harm was caused.
Whatever solvent you use the merest hint of WD40 sparingly applied to the top of the locking ring afterwards makes a huge difference to the ease of subsequent fastening/unfastening. Left dry there seems to be a lot of friction at that point, especially, I have noticed, on stainless steel bodied connectors - I find a drop applied from the end of a cocktail stick is ample.

I have a bunch of type N attenuators and connectors where the electrical surfaces are in good shape, but the outer body is cruddy with sticker goo, grime, and who knows what.
Any suggestions on how to clean these without causing damage?? I'm guessing some sort of solvent bath plus a toothbrush would do the trick, but I don't want to dissolve anything important.
Thanks,
John
