If your using a water soluble flux, in theory it should clean up with dish soap, otherwise get a good anti-flux cleaner too. It is used to remove most of the flux, and allows the soldered areas to polish up nicely. A came stretcher will fix that and make the glass opening a little smaller for a snug fit. After this there are many other hand and power tools available. Some make it easier to apply foil, make more accurate cuts, or organize your workbench.
Some tools are single purpose and suitable for making only one type of project.
Some tools look like smaller versions of wood working tools, only with water cooling added because glass is tough on tools. These tools probably go beyond the scope of an FAQ in scope, therefore they won't be mentioned here.
