I can't find the beginner's soldering kit that you list above? Will you please suggest another. I'm just staring out and learning by video. I absolutely love your studio. Mine is much smaller but I have hopes to get to your level....Cheers!
The best product I have ever found to prevent this is by Jax Chemical - It's called Tarnish Preventer For Brass. You'll want to dip your whole piece in :)
