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

Really nice to have around.

Used to clean Marshall and Peavey 5150 tube sockets. Worked very well. A drop goes a long way. Finish with Deoxit Gold

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.

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.

I had heard great things about this one. for years i thought that was just marketing hype... i was wrong... this changes everything. Every audio engineering academy, university or school should give one this each of their passouts. it will last the rest of their professional lives and then some.
