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

Decent price and you get it quickly. I use this exclusively for dissolving gunk in potentiometers and jacks.

I purchased this product proactively so I have not used it yet, I am anxious to try it on a noisy volume control.

Friend of mine recommended this to me. SO I got it after trying just about everything else I could think of trying to get a car with an older fuel injection system running. Applied just a drop on the contacts of three of the sensors and two of the injectors, did a little light cleaning, leaving a coat of Deoxit on the contacts - bingo - car started and has been running without a hitch since. Car is a 1993 Saab - over time electrical contacts can get a little corroded. Deoxit cleaned them right up. Highly recommend keeping a bottle available,

you get what you pay for and this stuff is a very effective corrosion inhibitor. By the nine divines this stuff is ludicrously expensive however.

I know more about PC boards than I ever wanted. Tech in US Air Force. This product does a fantastic cleaning up corrosion and protects against further damage caused by humid environments.

Brought back old pots faders and switches I thought were gonna be scratchy forever.

I used about 1ml and dis all memory cards, a really scratchy volume control on a 30 year old classic shortwave radio, Many audio plugs and jacks. You must buy this NOW. You will love it.

great stuff! Much better than hardware contact cleaner

I swear by this stuff and have used it for over 10 years. It dissolves oxidation and dispenses dirt/grime from contact surfaces. Recently I used it on rotary switch contacts. The silver plating was no longer shiny but black from oxidation. Applying Deoxit to a cotton tipped applicator allowed me to scrub the contacts clean (back to shiny new) resulting in more reliable connections. The rotary switch is on a VTVM, so having contacts with no resistance goes a long way to promote meter accuracy. A little Deoxit goes a long way so the needle point dispenser is the perfect way to control how much of the solvent that you are applying.

I have been using Caig Lab products since the 1980s! Originally, their deoxydizing product was called Cramolin. They had to reformulate it to conform to new regulations. It is now called DeOxit. Available in 5% spray can (D5), or in 100% concentrate (D100L), accept no substitutes. Go to the Caig Lab web site and see which companies use Caig Lab products, including DeOxit. (Tip: one of them is NASA!)
