Lubrication of a NEMA 14-50 (240V, 50A) electrical outlet?

Q: (18567)

I’d like to make plugging and unplugging a lot easier.
Which DeoxIT product is safe for this voltage and current?
Would the DeoxIT Fader make more sense since it’s got a higher about of lubricant?
Does DeoxIT add resistance?
Do I need to worry about arcing and flammability of the solution?

Thank you,

Cleaning an antique 1970’s Moog synthesizer

Q: (18564)

I’m very nervous to use any chemical product on an ‘antique’ 1970’s era Moog synthesizer. However, the keyboard contacts as well as the ‘variable resistor’ knob pots all require cleaning – some feel sluggish to turn and have audible scratchiness when turned. Of all your products what would be the best and safest product to use – I’d prefer to keep the application of the chemical very ‘defined’ and avoid overspray.

Thank you,

DeoxIT D5 – use on silver plated contacts – how long will it last?

Q: (18545)

This is Simon. may I ask some questions about  D5 Spray, D-Series?

I cannot find the effective time of the DeoxIT® D5 Spray, D-Series from your datasheet and website.
I would like to use your D5 to avoid oxidation on the silver-plated metal of products.

Do you have any suggestions for how often to use your D5 on my product? and how long is D5 effective time?


Need to repair my EV car charger and looking for tips.

Which product and process is ideal to clean plated metal contacts? Need to repair my EV car charger and looking for tips.
Doesn’t always connect properly.


What do I use on RCA plus and sockets with ferrous and non-ferrous metals?

Q: (18522)


I have DeoxIT D100L-2C & DeoxIT Gold G100L-2C, 100% 2ml tubes. In some equipment it is impossible to understand if the metal part inside of a female RCA plug is ferrous or non-ferrous – unfortunately it is not the same metal as the outside. Here is my question: assuming that the RCA is clean and has either no oxidation or slight oxidation and without knowing if it is ferrous or non-ferrous, which of the two products I have should I use?

Cleaning of AC connectors; Pin and Sleeve, Single Pole Staging Cam-Lock, and Twist Lock?

Q: (18520)

I’m wondering what you recommend for the cleaning of AC connectors; Pin and Sleeve, Single Pole Staging Cam-Lock, and Twist Lock.
Some examples:  Primarily Hubbells HBL2613, HBL 2623, HBL460P7WR, HBL330C6W, HBL400 series.


Hybrid Battery (600VDC) applications which calls for treatment of connectors (both high and low voltage connectors)

Q: (18512)

Message: I noticed a Field Repair Guide for one of our Hybrid Battery (600VDC) applications which calls for connectors (both high and low voltage connectors) to first be cleaned/lubricated with DeoxIT D5 and then filled with Dow Corning DOWSIL-4 or MolyKote Dielectric grease.

Is this something you’d approve of (using both DeoxIT and a grease)?  Are there any issues you can think of where doing this could be a problem down the line a few months/years?

Is DeoxIT alone sufficient to clean, lubricate, and protect connections?

Thanks, Steve T

IDC connectors on the black PCB and the wide ribbon cable are intermittent

Q: (18509)

Hello Caig,

In the attached picture are the 2 connectors which give me troubles – loots of intermittents.
Attached you’ll find the datasheet for the IDC connectors on the black PCB and the wide ribbon cable, Unfortunately, I don’t have any datasheet for the 2 x 17 connector used to stack the 2 smaller boards (which BTW gave me most of troubles).
For what is worth, visually the contacts surface seems to be quite similar to the contacts of the IDC connectors.

Looking forward to your comments.

Best regards,



Need a product for our bridges. Lubricating, cleaning and protecting solutions for lift gearing, locking and limit switches.

Q: (18490)

Our most important concern is our exposed limit switches (rocker and plunger-style) which tend to accumulate grime from spray lubricants, road surface dirt, and winter road salting. We are in a freshwater environment, but exposed parts do take a beating.

We are also looking for a lubricant to help with our safety tail lock pads that tend to flash rust from damp and cold environment.  The main arm and pad are pushed into place by hydraulic arms. Our issue is the base pad of the bridge structure rubbing against the tail lock pad.

Third issue we run into is extreme cold operations on our exposed bridge gear & rack systems on a 1936 double leaf steel bascule bridge. In normal weather we use MobileTech lubricant, however in winter we have to mix it with another lubricant to make it adhere to the gears or it will flake off.  Not exactly something we like to mix up.

We have some photos of the limit switches and tail locks if you would like to see some of our systems.
I am familiar with some of your spray products as I use them on older Amateur Radio equipment I own (and highly recommended by other older operators).

Thank you,
Howie Hathaway
