Caig Labs D100L-16BX DeoxIT D-Series D100L Mini-Brush Applicator

I used it on the contacts of a 30 year old stereo.

Hands down the best stuff for automotive electrical cleanups!

Did nothing on old green battery corrosion. Had to go out and purchase lemon juice which removed it right away.

I used this on a corroded phone power connector that wasnt working well and a Datsun alternator terminal. Both are now working great.

Bought to clean some crackling pot switches on a DJ mixer. Worked like a charm.

I had a rusty/broken wire cord that was used to operate an electric motor, I was recommended to try this product and it seemed to have fixed my issue. Would recommend if you are faced with an unknown wire issue

I use this every day. The brush is definitely the best way to clean most connectors. Refillable. Super seller. Would definitely buy from them again.

Works great on connectors, etc. I just made my sd card socket on my tablet much more reliable with a couple drops

I liked that it arrived quickly and wasnt requiring packaging as well as that it is concentrated Deoxit. I thought about diluting it myself but couldnt think of a proper solution to mix it into. I had 90% IPA and Distilled Water but didnt want to use water and thought Isopropyl Alcohol may not work well with Deoxit. I disliked that it is such a small bottle and I nearly spilled it a couple times. I now keep it in a small tackle box with other small tools and such. I use it on connectors both power and data as well as electronic components that are oxidized or I want to be more responsive.

Used on HO scale nickel silver track to help stop locos from jerking motion due to soiled track. Works great.
