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

This is a nice electronics / contact cleaner that just works. I like the needle applicator as it lets you get the cleaner right where you need it without making a total mess. Recommended.

Great item for the slot car nerd to make good connections at track joints

Container/applicator allows precise, pinpoint application. No waste or mess.

Ive only used this a few times so far (corroded provision plug for car cruise control actuator and a couple battery terminals) but it seems to work great. As a warning I believe it is supposed to be conductive, though, so you might want to use electronics cleaner to blast it out on smaller connectors that have very close electrical connections before you power the device up again.

Save me tons of money by cleaning the contacts instead of buying new parts. It works

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.

This stuff is magic! I have vintage motorcycles and electric guitars that have the occasional electrical issue related to oxidized connectors. The needle tip applicator makes applying a drop or two where needed possible without making a mess of things, and the connection becomes like new again. Because you can apply it easily and only need a tiny bit, this little bottle will last a long time.

I used thus stuff on my Pioneer dj mixer. The sliders was static cutting on and off. The main volume adjustments on the rear of mixer was static and one side (left side) would completely cut off until I lubed it up with that juice. Now the mixer works like brand new.

This stuff really works! Not snake oil!

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.
