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

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

Received this yesterday and applied two drops to the on off volume control switch of my 30 year old radio and it cleared up the cracking and popping sound when I turned it on. What sold me was that it is safe on plastic. I have seen some other cleaners that work very well cleaning electrical equipment but will cause some plastics to weaken and crack. This bottle will last me a long time.

Purchased smaller quantity of product first, it works so well I purchased the larger quantity. Have used product on everything from volume controls, flashlights and amplifier vacuum tube pins. Guitar amp did not provide consistent sound until the vacuum tune pins were cleaned. Great product and definitely refer it to Friends

Deoxit contact cleaner works great on audio gear, old video game cartridge contacts, and vintage electronics.

Saved my old Super Nintendo! Applied a small amount to the cartridges and the cartridge slot. Used a small brush and q-tips to remove oxidation and excess. Nintendo started right up and games played without hesitation.

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.

This is just as great as the DeoIT spray and I put this on some foam applicators and clean electric contacts with it. Most recently used it two days ago to get some light bulb socket adapters for Christmas lights to work and make them a lot easier to screw in too. I also use it on all kinds of other contacts, wires, and electrical connections with great results!

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.

Without a doubt, DeoxIT is by far the best product of its kind available. Ive used it many times to eliminate the noise in old potentiometers ... saving untold dollars in repair costs and probably saving lots of gear from the scrap heap since many of these were obsolete parts. THis particular supplier had a very competitive price and very prompt shipping.

This product came back to life my 1987 Teac EQA10MKII equalizer IN-OUT and PRE-POST switches. I was suffering last 3 years after trying quite a lot of products such as contact cleaners and the like. Tried to get parts, no way... It is the oldest equipment I own, and Im not going to replace it because it is wonderful. Thanks to Deoxit I can now enjoy the superb sound with no sound cuts, or poor contact scratchy noises anymore. Best of the best!
