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

great stuff. works on just about any electrical connection to cut down on wear and tear as well as oxidation.

This stuff works amazing! I am pleasantly surprised! I had some very corroded contacts on my car’s connector, I used this and within 2 minutes they looked brand new, now everything works amazing!!This little bottle will go a LONG WAYc so it is worth the money for sure!

This was mainly bought so I could use as a reference for what I use at work. As long as you properly shut the cap this will last awhile for the average consumer making it worth the price. The first time I had to use this particular product I was a little dismayed by the large brush making it difficult to work into a phone's charging port. However it does it's job I used it on a few cables and other contacts around the house; a flickering bulb in my bathroom gave me an idea of just how great it cleans the contacts. I did sadly have to apply a week later on the bulb which was in my bathroom but it hasn't flickered or had an issue turning on in months. Overall it's a great cleaning product to have on hand even if it's just kept in storage.

DeoxIt is a great product for treating contacts to remove corrosion and oxidation.I used it for my Harley Davidson electrical connectors.

Have used this product to clean battery contacts in flashlights, bicycle safety lights, remote controls where the batteries had leaked. the devices work almost like new.

This stuff works wonders for electronic connections for audio and video gear. When used as directed it can turn less than standard stock headphones sounding decent. Been using this stuff for years. Only get the gold treatment if both your connections are gold plated. Otherwise it’s a waste of time and money and it was not designed for this way. The red treats all connections well, no matter the metal type.

Works as advertise -- fix a chuch sound system that would not respond to typical contact cleaner highly recommend.

Excellent quality, easy to use.
