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

good size

This stuff works, Over the years it has made PCs with intermittent issue start working flawlessly. Just apply to every connector, socket, plug, addin card etc.

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

I am an electronics engineer and I can tell you that this product is by far the BEST for electrical connections. Its pricy, but worth it in the long run.

The strong version! Thick concentration of electronic parts cleaner. Really goes after that green/blue build up when batteries leaked.

Good one

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. Its 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 its 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 its 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.

If youve never used this stuff - its almost magic. Removes oxidation like nobodys business. HELPFUL HINT: it can be mixed with naphtha ( I do about 8:1- naphtha to Caig ), which will stretch it out quite a bit, plus naphtha is a mild solvent, and adds a bit more oomph. Naphtha also evaporates and leaves no residue.

This is the best stuff on the market to clean volume pots

I cannot get the needle valve to screw onto the bottle. Pretty much useless without it.
