DeoxIT D100L-2DB Brush Applicator, More Than A Contact Cleaner, 7.4mL, Pack of 1

A MUST have for working on cars. The full strength polyphenol ether exerts a powerful removal and protection from oxidation of metal contacts. It also has a lubricating quality that makes connectors easier to remove later. I used to get the smaller mini tubes and apply with a q-tip. But I find the small brush in the bottle make it easier overall to use. Plus there is no danger of loose fibers from the qtip coming off inside the connectors.

I purchased this to try and repair a small pile of 30 or so battery powered toys and have continued to use it as I find more. I see a lot of reviews upset its not a miracle product after trying it on a single device. I'll say after applying it to every item I had its effectiveness was roughly 70 to 80% of the items I tried it on. Sometimes pieces I was sure it wouldn't work on it actually did bring back to life, and other times items I thought barely needed it still wouldn't work. Its really dependent on how the corrosion happened, what areas it affected, and possibly your item might just have some other unseen issue. Its great for corrosion, tarnished metal, and battery acid buildup. But if the metal prongs themselves are damaged its probably not going to save it. This is a cleaner, not a magical time-rewind potion. The bottle is really small and I've seen some people say they used the whole thing on one item. Honestly after using it over 60 times I still probably have hundreds of uses left so I have no idea how some reviewers are using the whole bottle on a single item unless they're just dumping the whole thing in (which would definitely just destroy it) I'd recommend it if this is something you see yourself using more than once every now and again. Go in with realistic expectations that it could save your item, but consider it a last chance, not a sure thing.

Expensive little bottle but it does the job. Quickly cleans every connector. Apply and then wipe until cloth is clean. You’ll be surprised at how much crud comes off a ‘clean’ connector. Must have if you’re into vintage equipment.

Help me clean contacts. The bottle is great for giving you the exact amount that you need for small spots.

Amazing! Works like a charm to instantly clean musical instrument input jacks and eliminate that scratchy contact noise caused by the tiny amount of surface corrosion on contacts that have not been used in a while. Flashlight contact surfaces can also benefit from treatment with this product, which is easy to use and apply precisely to small contact surfaces.

I have a 1985 Porsche 911 which is all original. Over the last couple of years, I'd started to have issues with the spade connection in the ignition wire near the key. I'd plug and unplug the connection and eventually, I'd get a connection and the car to start. Then a couple of weeks ago, nothing I did could make a good connection. So I tried DeOxit on the male and female ends of the connection and let it sit overnight. (This is a key to the application process, it seems.) The next day the connectors looked like new and the connection has been solid ever since. I'd recommend DeOxit for any electrical connection that has oxidized and isn't working properly.

Works like it supposed to.

Great handy cleaner for any metal contacts. Usually use them on cable connections, like USB-C or USB-A after much use pulling out or putting them in. People don't realize how dirty and worn out these computer connections (Thunderbolts connections, etc.) can get. These tiny cleaners are great to carry around (I have the spray version but they are too big to put in my suitcasel) when I take my laptops and all my hard drives while travelling. Handy dandy.

Muy buen producto pero añadid al precio de venta casi 7 euros que te meten en la aduana española.

Works as described, highly recommended!

saved me a huge amount of money, since i did not have to change the computer in my truck.
