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

Ive used it on everything from vacuum tube pins to padlock tumblers. Expensive stuff but you get what you pay for.

Needle delivery into repair item. More precise delivery. The spray type seems to push more product into the cavity you are cleaning.

Ive used this high quality product for years and it lives up to all of the claims. Dont let the price for the small amount scare you away, this small bottle lasts a remarkably long time.

Worth the price, long time user of product

I swear by this stuff and have used it for over 10 years. It dissolves oxidation and dispenses dirt/grime from contact surfaces. Recently I used it on rotary switch contacts. The silver plating was no longer shiny but black from oxidation. Applying Deoxit to a cotton tipped applicator allowed me to scrub the contacts clean (back to shiny new) resulting in more reliable connections. The rotary switch is on a VTVM, so having contacts with no resistance goes a long way to promote meter accuracy. A little Deoxit goes a long way so the needle point dispenser is the perfect way to control how much of the solvent that you are applying.

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.

Very good item!

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.

Great product, and the most economical way to buy it. Easy to use with the pinpoint applicator.

Works great!
