Andy,  who is a regular reader of this blog, asked about the cleaning of metal after silver soldering. You can read Andy's reply in a comment.

I asked if Andy could send a photo of his work and I think you will agree that his 'test' piece is well soldered for something that small! For more information use this link http://www.workshopshed.com/
