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

Ive used deoxit in a spray can for years. It has always seemed to live up to the claim. The can however, wasted a lot of product. This bottle with the needle applicator works so much better, (in most situations). Not crazy about the cost, but now I dont spray it everywhere.

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.

This solvent works great to clean metal electronics connections. Very easy to use and the supplied applicator is perfect for applying just the right amount.

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 :)

Needle dispenser was great for getting into tight spots

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

This is good for cleaning noisy pots without having to do much disassembly. I just put a drop or two on the pot stem and it penetrates into the pot. I turn the pot a few times back and forth and give it a little time to penetrate and dry a little. When I use the pot later it works well with no scratches or pops when it is turned in use. I recommend using this for your amplifier or guitar pots that are noisy.

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.

I know more about PC boards than I ever wanted. Tech in US Air Force. This product does a fantastic cleaning up corrosion and protects against further damage caused by humid environments.

I am an electronics engineer and I can tell you that this product is by far the BEST for electrical connections. Its pricy, but worth it in the long run.
