I learned of a new bore cleaner on another forum and so even though I've got a cabinet full of just about every solvent you could think of, I couldn't help myself and have placed an order for a bottle of KG12 copper solvent. This company also has some other products such as KG1, KG2, etc., for other specific cleaning needs, but the copper solvent was all that interested me at this time. Has anyone heard of this product or better yet, used it?

Here's a link to the company: http://www.kgcoatings.com/
