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

Friend of mine recommended this to me. SO I got it after trying just about everything else I could think of trying to get a car with an older fuel injection system running. Applied just a drop on the contacts of three of the sensors and two of the injectors, did a little light cleaning, leaving a coat of Deoxit on the contacts - bingo - car started and has been running without a hitch since. Car is a 1993 Saab - over time electrical contacts can get a little corroded. Deoxit cleaned them right up. Highly recommend keeping a bottle available,

Used for restoring vintage ham radio gear, cleaning potentiometers, rotary switches, etc. Its amazing stuff. One swipe with a cotton tipped swab on switch contacts or a few drops in an old pot and theyre like new... Its expensive, but it does work, use sparingly.

good deal

This is the right stuff to put on electrical connections. This little 25mg bottle could last you a lifetime of dabbing little bits on various audio and video connectors. I use the thin probe tube to refill the DeOxit pen, you have to depress the tip to open the valve, with the tip up, and drible the oil down into the pen body. its a bit tricky but with practice,... the pens come with 6ml of D100.

Deoxit is what you need to spot clean electronic contacts.

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.

Without a doubt, DeoxIT is by far the best product of its kind available. Ive used it many times to eliminate the noise in old potentiometers ... saving untold dollars in repair costs and probably saving lots of gear from the scrap heap since many of these were obsolete parts. THis particular supplier had a very competitive price and very prompt shipping.

I used this on my old Mesa Boogie amp and also on my old Marshall plexi amp. Instantly cleans off corrosion and crap off sodered parts. Also makes old pots work like new. If you have static or loud pots, this should make them work as they are supposed to. Works great on electric guitar pots too.

Everything was fine
