Corroded cable plugs

Postby Airfix » Thu Apr 15, 2021 12:04 am

Like alloy wheels fuzz up - after three years behind the couch -
I need these XLR patches - so i will wash them with window cleaning fluid ( it cuts through the fuzz)- dry them - and spray them with wd40 and clean. Crap has eaten through the metal in parts - gnarly bits i removed with a beauticians nail file -
With my SOS right to edit - i edited that last bit -
Bloody cables - capitalists bastards - built in obsolescence swines - if only i had listened!

probably not a bad solution { :smirk: }, window clean would be vinegar based, i.e. slightly acidic & have a bit of soap too. Could cut through some oxidation layers and clear dust & spider poo. Cillit bang is another domestic caustic cleaning product.

Not sure about the WD40, its just an oil which might well prevent further oxidation but is a bit messy.

If there are gnarly bits, its probably time to renew your plugs preferably ones with a few microns of gold plating.

Bloody non gold plated alloy cable plugs! Your probably right - cheap me - serves me right all that scrubbing - i wiped off the wd40 and intend to use these cables. Bollix "$%*9 from the bottom of my heart- avoid cheap cables

Fair enough to avoid cheap cables but connectors don't have to be gold plated. I regularly use XLR connections in work that are over 40 years old with no issues. It sounds like behind your couch is a particularly harsh environment :D

Standard WD40 is an oily water-dispersant, not a contact cleaner. It has lots of uses but this is not one of them. You need to get that WD40 off before using the XLRs or you’ll be back in the same situation very shortly. WD40 film attracts dirt and dust. If you’ve used WD40 on your XLRs before, then that is probably why they got like that.

You need to remove the WD40 and use a proper contact cleaner like Caig’s DeoxIt or WD40’s dedicated contact cleaner product. Servisol also works but as it contains a lubricant, it is best used for cleaning potentiometers and sliders.

This sounds like damp corrosion, I use Servisol 10, always have done, does the job.

Airfix, do you live in the Bornean jungle? I have XLRs and jack plug going on 50 that have not corroded, dullish yes but not corroded. Jack plugs benefit from a spin with a plastic scouring pad MOISTENED with a little WD-40 once a year.

YES! WD friggin FORTY. I have a pair of mics in my garden and there is a total of 8 XLR connections. After six months or so, depending upon the weather, the system gets hummy/crackly. I split the conns, soak with WD and I am good to go again for another six months. I also treat the power co ax and BNC to the camera the same.

I don't like the 'feel' or smell of WD-40 particularly but it works for me!

WD-40 is a paradoxical substance that at once INSULATES insulators and prevents 'tracking' (as for instance on a distributor) but also improves intimate electrical contact. The while repelling water.

My experience of [UK] corrosion was from hanging my cables off of the end of the curtain pole.
Really handy !
The window was open all summer & by autumn the connectors had roughed up & tarnished.

There is some part of the UK where one might leave the windows open all summer?? :o :o :o

yeah, it was in a top floor flat, so no security issues. I was younger then & summers were sunnier, hotter, longer & more plentiful.

Thanks Wonks - big rabbit - in response to lovely others -- I do not live in the jungle. I have heard when certain metals touch each other (cheap alloys) while in a bag behind the couch for 3 years - it can cause a reaction - quantum stuff - and corrode my plugs - swine reality

Well, you can certainly get galvanic corrosion when two metals with significantly different electrode potential values come into contact.

But it's normally only significant with a liquid such as water present, to ensure an abundance of hydrogen ions to allow the reaction to occur.

Tested my recovered plugs on my tc helicon 'pedals'. Alls well. Although i will not be plugging them into my newly acquired Sound Devices MixPre 3 ii (sweet thing). Have ordered new fuzz free stuff (i hope) - - Stay safe -

Said this before here. Where you have a piece of tasty gear (and a MixPre is VERY drool inducing!) it is wise to make up 'sacrificial' adapters i.e. an XLR MIC plug to XLR female and then only connect to the flying socket thus taking any 'in and out' wear away from your Precious.

Same goes for microphones and two birds can be deaded as the adapter can be a thin, flexible cable with an LF filter 'knot' in it.
