In addition to the "wooden stemmed tightly woven Q tips that are made especially for electrical cleaning" mentioned by Dennis, AE6C, I also use the brushes listed below. A drop of DeoxIT on either goes a long way.
These brushes are great for cleaning 7 & 9 pin tube sockets: http://www.gumbrand.com/interdental-brushes/products/gum-go-betweens-proxabrush-cleaners-wide/872rn/ These brushes are good for cleaning RCA connectors, 8 pin and other larger tube sockets, etc: http://www.mcmelectronics.com/product/CAIG-LABORATORIES-AB-50-/200-288 Ken WA2LBI On Fri, Dec 23, 2011 at 13:06, Dennis Monticelli < dennis.montice...@gmail.com> wrote: > I have found that 100% DeOxit dries more slowly than the 5% stuff > because the latter is mostly carrier.
