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

I use this for coax connections and for refurbishing my TV remote contacts. I like this stuff and its why I bought a big bottle of it. It needs very little and it goes a long ways. I just never want to be without it.

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.

From pinball tables to airplanes, this is the best. Light sockets, scratchy audio pots, fickle low power connections, switches, etc.... Whatever you have that not only needs cleaning, but also electrical contact enhancement and protection. This size bottle lasts a LONG time, I have rebuilt 7 pinball machines plus countless other projects, still have half a bottle left!

In my sample, the dispenser nozzle did not work at all. I had to remove the cap entirely in order to use the product. Once applied, the product performed as advertised. Assuming that the dispenser worked I would buy this product again.

I have never seen anything work like this. I had several rusted and snapped fuses, fused to the main fuse box of my 70s muscle car. I used the long syringe to get it in as tight as possible. Closed the door, left it in the sun and came back an hour later after getting groceries. EVERYTHING wobble out as if it wasnt even rusted tight, shut, and sealed for ever. This stuff worked so good, I thought it would be banned as toxic or something. thats how good it is. Definitely a wonderful purchase AS LONG AS YOU DONT LOSE THE TIINY BOTTLE.

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

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

Purchased smaller quantity of product first, it works so well I purchased the larger quantity. Have used product on everything from volume controls, flashlights and amplifier vacuum tube pins. Guitar amp did not provide consistent sound until the vacuum tune pins were cleaned. Great product and definitely refer it to Friends

I find this the best form factor dispenser for D100. You want to use as little as possible, as thin as possible and this bottle can dispense very small amounts, precisely placed. This bottle should last most techs the rest of their lifetime. The spray can version is cut with solvent, not full strength, and wasteful. CAIG makes lots of other specialty versions: gold, fader, etc. but this is really all you need to prevent oxidization of contacts and connections. Worth the investment. Was sold as Cramolyn Red back in the 70s. Same great stuff.

Good product, performs as advertised.
