I recently acquired some old brass and copper bore brushes at an auction. They were loaded with string, lint, etc. I picked out a lot of it with a needle nose pliers but they were still pretty full. That's when I got a "brainy" idea. Drain cleaner dissolves cotton and hair and stuff like that without hurting metal pipes. Why wouldn't it work for this? Since there was no aluminum on these brushes I decided to give it a try. I started with a bent and twisted brush as a test run. After 5-10 minutes submerged in the drain cleaner I removed it and dropped it in a large container of water. Good as new! Bright and shiny with no lint. Has anyone ever tried this before? Obviously it would not be recommended on the bottle and I would not use it with any aluminum, blued or plastic parts. It is strong acid and is very corrosive. I am not recommending this, just letting you know my results.
