DeoxIT Gold GL100L-16BX

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!

Resolves oxidation issues on gold finger contacts (e.g. video game cartridges) and PCB flex ribbons.

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.

I suppose 100mL is 100mL but never the less must admit the bottle size surprised me! Don't expect much I suppose that's why they call it Gold !

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.
