I started using this mixture and it works very well. I had one thing happen that was a little unusual. I had a batch of brass fresh out of the tumbler and sprayed it down with the mix. I had stuff to do so I let it set over night. The next day, I had dark stains all over my freshly tumbled brass. I ended up running it through the tumbler again to shine it back up. Other than that, it works very well.

Stay away from negative people, they have a problem for every solution.
