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

expensive but gets to the areas you need and you dont need much

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.

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.

DeOxIt is a great product, and this is a far easier way to apply it than the brush cap bottle. Yes, this is EXPENSIVE, but it works every time and the needle applicator allows me to be more careful and economical applying the stuff.

A must have for restoring turntables and old stereo equipment. I acquired some vintage stereo equipment and turntables that were in dire need of some cleaning and TLC. CAIG products are a must when doing projects like this. Sticking, popping slider controls are now smooth throughout their operation and sound like new. Before you toss that old equipment, give this a shot. I might just save the life of your loved one (your loved stereo equipment, that is)...

Love this stuff! Brings old contacts to life.

All in one contact cleaner. Latter you can put your own juice in it.

Excellent product

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.

Good stuff. Beware around switch wafers, however.
