DeoxIT D100L-25C Precision Needle Applicator, More Than A Contact Cleaner, 25 mL, Pack of 1

This is great stuff for removing oxidation from metal components and screws. I used it to remove corrosion from a battery connector. For electronic contacts you want to dilute it in alcohol. It can damage Bakelite like surfaces otherwise.

Perfect! Replaced the GEM module and used this to make all the connections and it WORKS!. Im looking forward to using this in all my electrical projects!

Did a thorough cleaning of all electrical connectors on an older motorcycle using purpose-specific fine diamond files but there was still some residue that this product completely removed in just a few seconds. After flushing out residue with a dielectric cleaner and applying a little dielectric grease to each terminal prior to reconnecting, all circuits work correctly, as they did when new. Very effective product for this purpose.

Works great ! I watched the tarnish disappear !

Im at least the second owner of a medium format film camera (Mamiya RZ Pro II). The film holders for this camera are contained in removeable backs, and there is a system of interchangeable lenses. The camera is battery powered, and there is a system of electrical interlocks that sense whether all systems are go or not, before you can push the button and have it do something other than beep at you. There are contacts between the film holder and the camera body that have to make good electrical connection, a mechanical linkage between the back and the body, and similarly with the lens. It is not unusual to see questions from new users of Mamiya RZs on-line, asking how to get around the cant wind it or just beeps at me when I push the go button impasse. I could see that some of the round-ish gold buttons that are the contacts on my holders, had worn down to be a little flat - probably the backs came out of a professional photography studio where they received heavy use, being rotated from portrait to landscape orientation many times (one of the strengths of the RZ system). I was having systematic problems winding the film to the next exposure, finding by experiment that rotating the back after each shot seemed to free the winder mechanism. Before I sent the camera in to a repair shop for analysis and a minimum $100 charge, I decided to try the DeOxit route first. The needle applicator let me put just a tiny drop on each of the contacts (I didnt want an oily mess spread around the inside workings of the camera), and I also used it to lube the tip of the metal drive rod that connects the film back to the camera body, in case that was part of the problem. I did the same for the lens contacts. Whatever it was, for the first time with this camera, I went through an entire roll of film smoothly, with no beeping, no film advance lockup (a sign of electrical or mechanical distress inside). So, Im happy to have found DeOxIT. Now I just need to find a way to take it with me without leaking when I take the camera out in the wild.

I was not able to remove my pick guard completely to get to the switches and knobs that were scratchy and intermittent. The long applicator was able to reach these controls and the fluid did the job! Saved me a trip to the guitar tech.

This purchase was a restock. Im a retired commercial broadcast and instrumentation engineer. Ive been repairing all types of electronics from consumer to state of the art comercial test equipment since the early 70s. Ive been using Caig products since the early 1980s so about 30 years. It was first recomended to me by John Fluke Company for use on decade switches on an AC calibrator. (Not saying they recomend it now, just that they did then.) Since then Ive used Cramolin Red as this used to be called for countless applications. It is THE ONLY product I have ever seen that would satisfactorily clean up a noisy position potentiometer on an analog oscilloscope. (Gives instant feedback about how well it worked by smooth trace movement. Noisy potentiometer causes eratic trace control). When it came time to refurbish my Nakamichi 1000 recorder I used this to clean and treat the slide potentiometers, switches and edge connectors. I use a tiny drop on the contacts and switch on any flashlight I own. No more variable intensity. Caig makes other products for other applications. Ive used many of them. But this is the one Ive used most. It hasnt let me down in 30 years. For those technically inclined: How it works. Cramolin Red (Deoxit) is specially fomulated not to adhere to itself. Meaning it easily reduces to monomolecular thickness under contact pressure. The liquid itself has 10 x 10 to the twelth ohms per cm. But that resistance reduces to almost nothing at monomoleculat thickness it reduces to under contact pressure. In the meantime it desolves oxides and contaminents so they can be wiped away. It leaves a very light protective coating that blocks further contact oxidation. Be aware that it isnt a universal solvent. There was an older contact lubricant known as Rycon that with time leaves a wax like coating on contacts that must be removed mechanically (Pencil eraser). Deoxid wont remove it. But for treating clean or untreated contacts this stuff simply cant be beat. Doc

Magic elixir for electronics. Im used to using the spray but this is awesome of volume, tone controls. Ive also used on cell phone contacts inside the phone. Just a dab will do you :)

The material arrived undamaged, well protected in a tight blister-pack. After some effort to free it from the packaging, I tried it out on my Vibroplex Bug ( which was suffering from scratchy-dots ). There was immediate improvement, but not a miracle. Still a little intermittent contact scratchiness. To be fair to the product, the instructions state that I should wipe contacts repeatedly each time with a fresh cloth until oxidation is no-longer observed. I did not do that, I just applied product to contacts. So many projects in the pipeline - When I get back to this one I plan to apply DeOxiT in a manner fully according to instructions and will update the review. In the meantime, there was SOME improvement with just one drop, enough for me to get back on CW without shame of REALLY scratchy dots.
