I've got a few IP cameras down at the New Jersey shore where they are
subject to the typical marine environment.
Even the indoor connections are eventually affected.
Been using some stuff from Radio Shack (two cans: "DeOxit DN5" to clean
and "DeOxit GN5" to condition/protect after cleaning).
I use it on the RJ45 plugs and the RJ45 receptacles - which are
sometimes visibly blackened by the time a problem surfaces.
It works, but the cans are very small (14g net) and the stuff's not
Anybody got an alternative that comes in larger containers?
From the Synco Site
"Can Super Lube® be used as a dielectric grease?
Yes, Super Lube® has good electrical insulating properties and will
protect electrical and electronic equipment. Synco also offers a
Silicone Dielectric Grease version of Super Lube®."
I guess I don't understand "Dielectric Grease". If it has "good
electrical insulating properties", wouldn't it have the opposite of the
desired (good conductivity) effect if applied to the mating
electrical-connector surfaces? Seems like I'd want something with good
electrical conductivity properties instead...
I know that's way off-base, but can somebody explain why.
When you dose up threads, the metal to metal
conducts just fine. The grease fills the air
spaces, and helps keep water out.
However, if there is some grease trail between
connector A and connector B, you'd not want
power to leak from one to the other.
The connectors make good electrical contact all by themselves until
the corrosion starts. You want something that keeps the moist air out
with having any effect on the circuit. If the grease was conductive,
it would let current flow between adjacent contacts and cause
For once, WD40 is perfect for this type of application. The WD stands
for water displacement and WD40 is good for removing water from
contacts. I used some WD40 when my phone wire union got wet and I
lost POTS connectivity. A couple blasts of WD40 on the rain soaded
connectors/contacts and I was in business, again. ;)
You're the second person to mention salt water on this group lately.
Years ago I visited a non-close friend who lived near the Mediterranean,
and he took me sailing on his boat. Very nice of him, and I thanked
him a lot.
I wrapped my new digital camera in a plastic bag and wouldnt' take it
out of the bag, until we got in the car and went inland, I couldnt' tell
how far. Later I realized he was annoyed that I hadn't taken pictures
on the boat, with him iirc wearing his captain's hat.
I told him I was afraid of the salt sea air, but he denied it did
damage, or much damage, I forget. It's so good to know the two of
you think or even know that it does.
I used to have a seawater aquarium, and I'd find lots of salt on the
outside of the walls, all the way down to the table, and on the table.
I should have mentioned that to him. He died a few years ago.
In a thick film it is a good insulator. It has very little film
strength though, so when the fine wires of the RJ45 jack wipe the pins
on the RJ45 plug, they make physical contact - with oxygen and
moisture locked out. Using anything conductive would load or short the
line (conduct between wires). The stuff works good for light sockets,
spark plug boots,electrical connectors - anything you want to protect
from the elements. And it doesn't wash off. It doesn't attack rubber.
It doesn't damage paint, and it doesn't dry out and turn to stone.
It's also a VERY good lubricant for anthing you need to lube and
doesn't stain - and it's food grade - non poisonous and all that.
The only problem is it dries up and doesnt protect the connections
from getting wet again, and doesn't keep salt out, and basically
doesn't do much of anything other than chase water away. It might help
get rid of some corrosion as a cleaner - - -

The pot I've been dipping into for the last 10 or more years is their
#4160 400 gram multipurpose grease with PTFE.
Their 91016 dialectric grease may be better as a dialectric, but not
nearly as good as a lubricant.
I used to also have a can of their 31110, which is the multi in a
spray. For that use I'm now using Fluid Film.
Their syncopen product is supposed to be pretty good too, but I've
never tried it. It is used as penetrating oil in food production
You can use the dn5 in the full strength container, and mix it with alcohol
as a drip on fluid.
deoxit is a 5% mixture of the red stuff.
Actually, WD -40 works better as a cleaner.
I'm not sure If silicon grease is the best for water control. I think some
car recepticals come with it, or marine connections.
CRC 2-26 is pretty good as a do all. You can find it in the big can.
LPS-3 might work as a sealer.
Some times, the light bulb goes on....
I've had bad experiences with Ox-Gard or
No-Al-Ox, the grey stuff meant for coating
aluminum wires in panel boxes. Seems to be
a bit agressive, and has eaten away terminals.
