I back the Deoxit Product too. My work i look after 30 odd TV Station Broadcast ENG cameras. (P2 Panasonic rigs and a few Sony SX).... They have diecast magnesium bodies and in all machines the edge where body cover meats main body there's always a pile of white corrosion from the activity leftover from the usual rain splash days when he cameraman hasn't been quick enough to cover with its 'raincoat'.

I have found the red coloured Deoxit makes short work of shutting down the corrosion and in the process of maintenance i coat the same area with the blue or gold coloured product to really keep any water that wicks in there from messing things up.

Interestingly buy small bottles of the magic stuff that have an applicator brush and find they last a long time. Trouble is if i buy from a TradeSupply Professional here in NZ the price for a Deoxit kit runs out at NZD $55 but i discovered the same identical kit at a hobby electronics shop fro the sum of NZD $22 so stocked up well and truly!

Do those covers have wire-braided, rubber seals on them? I know that many field/ENG cameras do. I think the braid is stainless steel and being iron based against an alloy of magnesiou/aluminum, it creates a potential that is exacerbated when water (esp. mineralized water) comes in contact. I could understand why applying an petro-based deoxidant would retard corrosion.

Yes, you're onto it! These cameras have precisely that kind of electrical connect probably as a requirement for RF screening (probably under EMC directive) but it truly can result in a really bad mess.

One company suggested I could try using a thin wipe of mineral grease but most certainly not a lithium based one as with the magnesium it would really make for other problems.

As i've said, the best results i've had in removing the corrosion products and to keep them at bay has been with Graig Deoxit (the concentrated version.... NOT the one in aerosol spray form).... :-)
