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.

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

Best electronics cleaner/protector on the market.

My cars ECM had an intermittent connection that was causing the left bank of injectors not to fire, so I decided to give this stuff a try. Well I wiggled that connection to no end, and the engine didnt sputter not even once. I then put it on all my cars sensor connections. I really love this pruduct especially the fact that it is proudly made in the U.S. of A !!

Instantly remedied noisy volume pot on electric guitar.

I use this to clean rotary switches on 30 year old VOM. This cleaner works perfectly and the mini control tip is a plus over the usual contact cleaner spray cans. Highly recommend this product!

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

Love this stuff. As close to a miracle as Ive ever seen. Use it on contacts, plugs, batteries, computer cables. Improves conductivity of anything it touches.

This product works great at improving the electrical connection of connectors that are prone to oxidation. It lubricates and prevents further oxidation problems to restore normal function of your connections.

Ive had varying degrees of results with this. Didnt work as good on guitar pots as it did on amp pots. I got a used amp with extremely loud scratchy pots, opened it up and squeezed this stuff in them and most of them are almost quiet now. Didnt really help the noisy guitar switches. Very expensive but its enough for hundreds of pots.
