Detector Maintainence.....

I have a couple of older detectors in my collection which the coil plugs and connectors are badly tarnished.....
can anyone suggest a method of cleaning them.
Ta.

What about a bit of 1200 wet and dry
I'd use it dry
Blow out the grit
And give them a spray
Of electrical cleaner

But is it just the colour ? Or are they not performing
Properly , because of build up
If oxidisation

If the original coating is gone replace them or performance could/will suffer. Like SDs or GPs when the gold coating wears off after you change the coils dozens of times they get noisy and the machine sounds faulty. Put or get new plugs or connectors on and it runs like a different detector. Personally id go for new plugs or connecotors on anything that didnt look like it used to originally. Years ago I used to chop and change coils on my SD 2100 often, it got noisy and when I took it to the then still existing Finders the tech showed me the gold plating was nearly all worn off, when he replaced plug and socket it was like a new machine. I know a lot of US ones are not gold plated but I reckon if its damaged from what original looked like id replace. False economy to hang on to the old if they are damaged.
Just my two bobs worth.
