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

Great product. Did exactly as advertised.

Used this to apply to contacts on computer plug-in module that was not recognized by the system. The module was un-used for decades and the contacts had become oxidized. After a drop of Deoxit on the contacts and plugging/unplugging the module a few times, it was working again. Great product. This size bottle should last me a long time.

works as promised and the applicator tip gets the liquid exactly where you need it to be without waste.

THE best stuff have used it for years, dont fool will other brands this is what the professionals use.

Great product to use in electronics.

I cannot get the needle valve to screw onto the bottle. Pretty much useless without it.

Caig products are extremely expensive.I first tried the small spray cans.Big mistake.The stuff goes everywhere. Than I tried Caig DeOxit with needle applicator.Bingo! Just what I needed for precise and economical placement of the product.No waste and goes right where you want it to. Great product.Highly recommended.

Ive been using this stuff since the late 1800s in audio pots and switches. Audio guys have commented forever how this stuff lubes and quiets audio slider pots. My findings have always been equally as positive. I put a drop on the pots on my flight sim joystick. They are typically 10k, 90 deg ROM composition pots, doing the typical 5v thing to an A/D converter. They are often miniature pots, smaller traces, likely more prone to dirt/dust/bug poo. As expected, the drop of red stuff smoothed out the response very dramatically. What was a quarter to half volt spike with every movement of the pot became measurably zero spike. Smooth as a baby pots bottom. As smooth as any Hall Effect sensor curve. Heres the new use - I put a drop on the joysticks mechanical cams. Thats typically a machined and/or chrome surfaced cam and ride bearing affair with or without a center detent. I dont want oil or grease on these, they live in a desk mount joystick or in a set of flight pedals, constantly on the floor, being activated by the bottoms of the pilots shoes. I simply cleaned the factory supplied lithium/moly/bear fat grease off the cams and allowed one drop of DeOx to flow onto the cam bearing surface. The carrier disappears via magic pixies and apparently leaves the Business End part of the product on the metal surface. No dust collecting like with grease. The seemingly high price of the little bottle is not a factor. Man cave engineers will likely get 10+ years out of one of these bottles. Youre likely to change hobbies or die before you use up two bottles.

Decent price and you get it quickly. I use this exclusively for dissolving gunk in potentiometers and jacks.

This works great to clean the contacts of connectors, controls and switches; also for computer memory and plug-in cards. I have been using CAIG products for over 25 years, and in my opinion they are the best available.
