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

I apply this to a Q-tip and scrub my wafer switches. Much less mess than the spray can variant. And I use so little of it for any specific job that even though it looks like a small bottle, it should last me for decades.

Ive used it on everything from vacuum tube pins to padlock tumblers. Expensive stuff but you get what you pay for.

This is most useful for maintaining guitar switches and jacks. It stopped crackling and dropouts immediately. Also works for restoring continuity in motorcycle wiring.

Everyone should have some of this on hand to keep all of their electronic/battery operated devices working at their best. Ive been using this for over 30 years, and know from experience that IT WORKS GREAT! Keep contacts clean, conductive and rust free. A little goes a long way, and it will pay for itself in battery costs by extending the their usable life.

Works as advertised. Great product to say the least.

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.

good deal

I think it it did the job , I used it to get some rust from the frame of a window.

Container/applicator allows precise, pinpoint application. No waste or mess.

Great item for the slot car nerd to make good connections at track joints
