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

I got what I asked for, and that is what it is all about. Product works just like its supposed to work. Good stuff.

I think it it did the job , I used it to get some rust from the frame of a window.

Works as advertised and corrected my corroded electrical contacts.

Good product, performs as advertised.

This stuff is magic. Buy the small nail polish size with a brush, then refill from this. I use it on EVERYTHING. Before putting batteries in anything, I brush some on the battery spring and contact. No more jiggling flashlights. Ever. Those cheap aluminum LED flashlights that have sections that screw together - aluminum oxid (rust) is an insulator (read flashlight dies). Unscrew the new flashlight sections and apply a drop of this to each threaded section and reassemble. I use a little on USB cables. No more intermittent connections. Anything thats bare aluminum or bare copper us going to oxidize/corrode without thus stuff. I put it on bare twisted copper wire before using a wire nut - like on my landscape lighting. Without it, you might get an intermittent. You come back and the copper is black. Theres no way to get a good connection, short of stripping back at least six inches of wire... Twist each wire, brush some magic on. Twist them together and use the wire nut. You wont get an intermittent, and if you come back to re-wire anything, youll find the wire uncorroded! Seriously. Any place metal and electricity collide, add some of this and everyone will be happier. Trust me. You will not be disappointed. It may seem expensive, but a little goes a long, long way. (I use it a LOT and the nail polish bottle lasts me at least a year, my refill bottle just ran out after maybe five years.)

I like the control the needle applicator gives to this great DeOxIT product when I dont use their spray. Wonderful product for cleaning and preventive application.

Use DeOxit to enhance electric contact to any appliance switch or electrinic device thats making intermitent or deficient electric contact. Flashlights, photo eq., flashes, hot shoes, batteries and battery compartments, cable connectors, etc. The needle applicator lets you can precisely put a drop or two on both surfaces that should make electric contact and presto. It deoxidizes and lubricates switches, contacts or any other part that you suspect may not be making adequate connection. Great for flashlight threads and battery end contacts as well.

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

It works for stuck keys!

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
