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

The strong version! Thick concentration of electronic parts cleaner. Really goes after that green/blue build up when batteries leaked.

Ok

Works really well but lil to pricey

I apply this to a Q-tip and scrub my wafer switches. Much less mess than the spray can variant. And I use so little of it for any specific job that even though it looks like a small bottle, it should last me for decades.

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

Not sure about vol rating, lol but great product expensive for such a small bottle but great applicator

lube for radios

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.

A must for electronic buffs

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
