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

I have used DeoxIT for years in my career in the electronics repair business. Those infuriating intermittent problems, caused by slight invisible-to-the-eye oxidation of connectors or switches, magically disappear! This is especially true of very low current connections. Many times DeoxIT has been the one thing that suddenly completed the service call. Around the house I have used it to clean inside the tiny micro-switches on computer mice and eliminate unintentional double-clicking. That beats having to de-solder the offending switch and solder in a new switch.

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.

Came across a 45 year old stereo receiver that had been stored in an attic for 25 of those years. It looked like it was ready for the trash but a few drops of this in the POTS and some on the other moving parts and its now working great. I even used some on the rear RCA jacks which cleaned up the audio. The needle applicator made it easy to get into the narrow spots and there was no worry about wasting product with overspray. I highly recommend this product.

This stuff is liquid gold. I have a Headphone Amplifier (Drop THX AAA 789) that after a year developed volume pot scratch which unfortunately is all too common with the 789. A few drops of this stuff while turning the pot up & down fixed it right up. Secondly I have a Fiio portable audio player DAP that has a volume wheel on the side. I wasnt getting volume scratch but it was jumping the digital volume number on the lcd whenever turned it. I would turn it up a few clicks and it would go from 10 to 99 back down to 10 then 30 without me even touching it. It was crazy.. I didnt think this stuff was gonna work but a few drops later... Its like new and fixed. I was pleasantly surprised concidering I didnt buy it for that item.. Magic stuff I tell ya.

Holly Toledo! This bottle is about a 300 year supply given that I only use on my camera gear a couple of times a year. Works great abd a huge improvement over the spray style they offer. I have gone through 2 cans of the spray stuff andwas lucky to get 3-4 uses before they ran out. With this liquid style bottle I just put a drop or two on a Q tip and clean the electrical contacts. It would be harder to use this style applicator on recessed contacts but for those easily reached it works well.

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

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

Great product for guitar and electronic potentiometers seems to be less waste and mess than the aerosol version. Does fantastic job at restoring noise issues

One of three Caig products that no audio enthusiast should ever be without. Regardless if the music you play is through a Home stereo System or a finely tuned electric Guitar and Amplifier. This product cleans and Lubricates the potentiometers in your system. Virtually removes scratching noise in volume and tone controls. The included needle allows for precision application. A little pricey but youll only need to buy this product once. Unless you loan it to friend that doesnt return it.

This is great stuff for removing oxidation from metal components and screws. I used it to remove corrosion from a battery connector. For electronic contacts you want to dilute it in alcohol. It can damage Bakelite like surfaces otherwise.
