CAIG LABORATORIES DeoxIT® Gold Mini-Brush Applicator, 100% Contact Conditioner, 1.6mL - G100L-16BX

Fantastic product. I use this on new cables before I plug them in first time and maybe monthly or so on existing cables. Not only helps the sound but makes plugging and unplugging cables easier. This is def easier then using the small tube which I also have. Kinda pricey but a little goes a long way.

Used to clean contacts of twenty year old outdoor light fixtures, worked just fine. Applied solution to q-tip to maintain cleanliness and was able to clean six two lamp fixtures (twelve contacts) and only used about ten% of bottle.

I got this to clean up the contacts on a vintage Canon lens that was not responding to autofocus signals. It cleaned the contacts on the lens just fine but unfortunately the autofocus still was not working. The lens is vintage early 1990's so I guess I should not complain...plus it works fine in manual focus. I do have other lenses which I will apply this material to.

Our internet speed declined significantly, and the cable company guy's computer was much faster when he tested it on-site. I learned that my dual monitors slow internet speed (who knew?) but cleaning the interior and exterior contacts with this obtained another 100 mps. NOTE that the instructions say to first treat "severely oxidized" contacts with D-series and then with this stuff (this is G-series). I'm assuming mine weren't that bad. The bottle is small but goes a long way. The applicator is a small paint brush which you have to crush to break it up to get the most coverage (otherwise it's like a pick). The cap didn't come off easy but it just twists (I used a paper towel to improve my grip). It doesn't leak as someone else found. Good luck!

perfect for what i needed

Im not one to leave reviews other then leaving ratings. This stuff warrants a review. I have a 10+ year old mag light that was not as bright as it once was. I was about to order all new lights and rechargeable batteries for this and saw this from a friend. SO I decided to give it a try. I used the brush and put some of this liquid on the contactors and battery. The brush is very small and I thought I didnt apply enough. I put the flash light back together and turned it on. I was AMAZED, just as bright if not brighter when I first bought it. I was a believer in this product. I have several cnc machines that are getting this on the drivers and VFD.

When the bottle arrived I was a little shocked at how small it actually was. However after using the little applicator on my RCA connections, I was satisfied. It only took a drop or two to clean the connector surfaces, and now I have no more sticky plugs. I'd give it a 5-star as far as performance, but I'm dropping it down to a 3-star only because of how much they charge for this stuff.

I needed to apply to contact pins and this worked perfectly. I have some in spray form which works well in certain applications, but not where precise delivery is necessary and overspray is to be avoided. Worked perfectly.
