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

I got my first electric guitar over 15 years ago. For the past several years, I rarely touched it - the pots and pick up switches were so corroded it wasnt worth the struggle to play. I few drops of this stuff and shes as good as new! No noise whatsoever. I dont know why I waited so long to try this.

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

I have an Owon scope and the rotary encoders that control the trace location and other things were erratic. Other people replaced them or the whole assembly. Someone fixed by adding decoupling capacitors. I was lazy so i tried DeoxIT. I applied it only to the shaft under the knob three times 1 drop a day apart. It is been a few months and it is still working. For the negative; it is expensive. I could have replaced all the encoders for what i paid for this and the DeoxIT slider product. (i used both) . I still have most of it left for other projects.

Everything was fine

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

I have been using the bottle with brush applicator for almost a decade. And when it was about to run out, I got this to refill the brush bottle and at the same time have a syringe-like applicator for delivering into tight connector spots like in surface-mount interfaces. I use this in tandem with the usual pressured spray can contact cleaner first, then apply this one. The contacts are maintained at high-efficiency maximizing signal transfer and preventing intermittent problems due to poor connections. My go to choice for connector maintenance and reconditioning.

Electronics

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

This is the right stuff to put on electrical connections. This little 25mg bottle could last you a lifetime of dabbing little bits on various audio and video connectors. I use the thin probe tube to refill the DeOxit pen, you have to depress the tip to open the valve, with the tip up, and drible the oil down into the pen body. its a bit tricky but with practice,... the pens come with 6ml of D100.

the nozzle applicator thing could be longer but it worked
