Brad, I read up a bit about electrolysis and while the method appears gentle on the metal there are some concerns/doubts. Can I use it on brass ? asking because brass is a copper alloy. I use a very small single car garage with no ventilation (once I close the front shutter) as my shop. The hydrogen formation seems a bit worrying if the process takes more than couple of hours & I have to leave the process unattended in my small shop.

Brass cleans up nicely using electrolysis. And the hydrogen produced is a non-issue… there is so little produced, and it is almost instantly harmlessly dissipated into the atmosphere as soon as the tiny bubble bursts. In fact, it’s pretty fun to pop them with one of those long nose grill lighters :) Just as long as you don’t cover the container, there is absolutely no worry (and even then, it’s minimal). If you do want to produce hydrogen to use, google HHO (Browns Gas) generators. They make fantastic torches and sources for alternative heating, and can be powered by solar cells. The torches are awesome and don’t get hot, but can melt lava rock, glass, stainless steel and even tungsten (melting point of over 6000°F)!
