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

I think it it did the job , I used it to get some rust from the frame of a window.

Does exactly what it says on the bottle. Since a little goes a long way, this bottle will last you quite a long time. Great for fixing up all sorts of electrical/electronic contacts. Improves and protects battery contacts, headphone jacks, computer cables and so on.

A must have for restoring turntables and old stereo equipment. I acquired some vintage stereo equipment and turntables that were in dire need of some cleaning and TLC. CAIG products are a must when doing projects like this. Sticking, popping slider controls are now smooth throughout their operation and sound like new. Before you toss that old equipment, give this a shot. I might just save the life of your loved one (your loved stereo equipment, that is)...

I just finished my other unit which was a smaller squeeze tube. This is much more quantity and allows for better precise application. I have another spray which is for harder deeper reach areas. This model wont lose pressure which is great over long time ownership.

Just wow. What a difference this stuff makes in a toxic environment full of corrosion and acidity. Connectivity is everything.

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.

Managed to restore my original Korg MS-10 Synth from noisy scratchy control knobs and connectors, to a perfectly functional and QUIET state.

This is a nice electronics / contact cleaner that just works. I like the needle applicator as it lets you get the cleaner right where you need it without making a total mess. Recommended.
