Soldering has become a integral part of my modeling. Much of my work has been, and continues to be, installing decoders as well as a variety of other soldering projects. During the soldering process, I typically I have been cleaning the iron tip with a damp cloth. Earlier days I was using the accompanying sponge. By the way I use a Weller, the most common one which can be purchased with its stand and sponge. Then my friend Ray Russell was here doing some soldering work that had me stumped. I offered a damp cloth and he gave me that.. "Are you kidding me?" incredulous stare. I responded most curiously knowing I evidently was still on the learning curve. He showed me this miraculous device that not only cleaned the iron nearly instantly, but avoiding the damp cloth eliminated the wait time till the iron reheated. One other most important element was that the iron was not subjected to mineral deposits from the moisture. You may say these are quite insignificant. I would say that if you do solder, this device will have a marked improvement on your time and process. The brand name is Hakko. I found this one on Amazon. You just insert the tip in the mesh a few times and its ready for the next melt.
