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

Worth the price, long time user of product

This stuff is magical. Used it on several vintage electronics. Cleared up static plagued knobs and restored function to those that didnt work.

Very good item!

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.

Deoxit is a great cleaner/enhancer for electronic switches and connections. I use a very small amount on all blade connections and plugs.

Ive used it on everything from vacuum tube pins to padlock tumblers. Expensive stuff but you get what you pay for.

The best!

DeOxIt is a great product, and this is a far easier way to apply it than the brush cap bottle. Yes, this is EXPENSIVE, but it works every time and the needle applicator allows me to be more careful and economical applying the stuff.

I purchased this product because I have long since recognized its excellent de-oxidizing properties and have previously used the same product in a spray form. I now needed a larger quantity because it has saved me so many times from disasterous situations where nothing more than a bad or intermittment connection has caused one of my electronic devices from working. I like the long needle applicator and am better able to control exactly where I apply the product. I am always amazed when a failed device comes back to life after just one application of this product. It is now my Go-To solution for any failures that could involve a dirty contact or oxidized contact or something that just plain doesnt work when it should. This has saved me an untold number of hours in trouble shooting time and I would never want to be without this as a first step in trouble shooting appropriate circuits.

Good stuff. Excellent contact cleaner. Needle applicator very handy. Use it all the time for my vintage audio gear.
