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

Works very well

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.

Excellent product — Works like magic! We call it Yum Yum sauce for electronic connections!

I have used DeoxIT at work for years. If you need to remove oxidation from electrical connections, this is the best. This is a surface cleaner. An example is the surface of rechargeable batteries, and the connectors used to connect to the batteries. Another example is fuse holders.

Very good product, easy to use

Delivered a measurable improvement in sound quality on the connections with my vintage Damici AV receiver and the various components. Also used it to restore the functionality of several remotes. Everyone with electronic components that require a strong connection could avail themselves of one of these.

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.

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.

słabo sobie radzi, lepsza jest jednak IPA

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.
