Hi, Brian. Thank you for the post. I haven't tried to do any cleaning at all so I'm really happy that you addressed that aspect. You mentioned professional cleaning - how does one go about finding someone who does that? Would the value of the iron tsuba warrant that? (As you see, I meant it when I posted that we are totally clueless when it comes to these items. I found your excellent forum through Google as I was searching for information that might enlighten me, if only a little. There is so much to know !)
