CAIG LABORATORIES DeoxIT D100L-25C Precision Needle Applicator, More Than A Contact Cleaner, 25 mL, Pack of 1

i saw some one on youtube use this to clean their game cart and also put some in a pot for a 2600 paddle. so i got some and boy does it work well! especially for cleaning the contacts on a virual boy for the displays after solder fixing them. i also tried it out in the volume knob and and its as smooth as silk after applying when turning it and the sound is no longer crackly. it works way better than wd-40! all though the price is high i will be using this sparingly. one thing i really like it the fact that it absorbs in to tiny cracks making it easier to oil a pot. If you work on old electrics this is a must!

There is nothing better to restore the function and add longevity to old (or new) potentiometers, switches and connectors. I have used it for decades. I suggest buying the small bottle with a needle dropper on it. The spray cans are effective but waste a lot of the valuable product.

A little pricey, but as they say, "you get what you pay for." Will definitely be buying more.

Yes it's expensive, but........ Nothing else on the market works as well as this stuff does, nor as fast as it does! I've tried nearly every contact cleaner and keep coming back to this. Gladly paying the price of entry. I would not spend the money if it didn't perform! It's really good stuff and is worth what it costs!

I used this on an old WWII‑era military surplus variable coil with silver‑plated parts. Before cleaning, the coil was extremely intermittent and felt rough while adjusting—I wasn’t even sure it could be saved. After applying just a couple of drops of DeoxIT D100L‑25C, the adjustment became perfectly smooth and every intermittent issue disappeared. For something that’s been sitting around since World War II, that’s impressive. Don’t be fooled by the small bottle—a tiny amount goes a long way.

This is an excellent way to keep bare copper contacts in a mech mod in good shape. It removes light to medium oxidation, protects and keeps contacts cleaner longer, and provides for better conductivity than other contact cleaners. It's also good for cleaning bare copper threading. It has help cut arcing way down, and improved performance. An easy way to keep mech mods in peak shape. It should not, however, be used on plated contacts since it's too aggressive and can damage the plating. DeoxIT Gold is the one to use for plated contacts -- the red is only for bare contacts. It comes in a lot of different formats (dropper bottles, spray, cleaning wipes, cleaning tips). This version is the most economical since it's 25mls. The thin needle dispenser is great for minimizing waste -- only a small amount is needed per use. It comes blister packed, and made it through the mail with no problems at all.

Mine didn't come with a cap or plug for the needle valve and so it leaks everywhere and I've wasted much of it, otherwise it's a great product and doesn't an excellent job cleaning oxidized electric contacts and keeping them firing well.

Decided to try and repair a remote where some of the buttons had failed. Followed the instructions and now I have repaired 3 old remotes! I am telling all my buddies how great the product is. Saves a great deal of money.

Really nice to have around.

Amazing product, expensive but worth the money, use it sparingly, mix it with Isopropyl alcohol to use on model railway track and rolling stock wheels.

Por el precio sinceramente pense dos veces en comprarlo, pero una vez que lo use ... ufff no hay nada parecido que haya usado antes (creeme, le busque a fondo). Es un producto costoso pero si eres amante de la electronica y quieres darle mantenimiento a tu equipo no vas a encontrar nada parecido.

Arrivato tutto ok, consegna nei tempi.

Works Great.....
