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

This stuff works, Over the years it has made PCs with intermittent issue start working flawlessly. Just apply to every connector, socket, plug, addin card etc.

Relegated to electronics this might provide some benefit but for wiring on motorcycles and cars, it really doesnt do much. This cleaner never really gets past the tarnish/corrosion on copper wire. I tested two pieces of the same wire, one dipped in vinegar and the other had Deoxit applied. No comparison, the deoxit did virtually nothing even after hours. The vinegar was a drip in, rinse and then spray with one of those moisture removing formulas found in auto parts stores and it was as clean as new. Sure, there is the idea that vinegar is an acid and could compromise the wire but Im not talking about dunking the insulated wire in it, just the end that is bare where a connection is made. After cleaning, a suitable film barrier will keep the connection working properly. I imagine that much of the claims made about deoxit come from just disconnecting and reconnecting the wires that dislodges corrosion and really has little to nothing to do with the deoxit. Unlike silver where the tarnish layer doesnt affect current capacity, on copper that isnt true and that is where the simple disconnect/reconnect improvement has some real benefit. In summary, for the rather high expense, save your money, this isnt going to clean copper wire any better than any other cleaner that costs far less and cant come close to some household methods that cost almost nothing. In all fairness, Deoxit might act as a barrier to reduce corrosion after cleaning with something else but given that the company seems to have a multitude of liquids for various steps the idea of cleaning contacts and wire connections for automotive type uses can quickly become more expensive that a new wire loom.

Love it

Great product to use in electronics.

Just wow. What a difference this stuff makes in a toxic environment full of corrosion and acidity. Connectivity is everything.

Had a noisy audio connector for years. Tried a drop of this just to see if it would help. Fixed it up completely. Not just for controls and switches!

the nozzle applicator thing could be longer but it worked

Ive been using this on automotive applications, electrical connectors specifically. Sometimes they get white corrosion on them. This stuff seems to work really well on that. I have also been putting it on grounds and other connections and it works great. A little goes a long ways.

Good stuff. Beware around switch wafers, however.

So easy to apply just the right amount. Tube sockets, pins, and relay contacts. Use on air capacitor bearings and control shaft bushings. 25 mL will last over a year of frequent use.
