Sorry again.
The pictures I found online seemed close but not quite right. I finally got a chance to go look at the actual can.
The product is SafariLand BCF Bore Cleaning Foam.
It doesn't appear to contain ammonia. It's primary ingredient is 2-Aminoethanol (Monoethanolamine) according to the
MSDS.
I can't believe how much and how fast the stuff removes copper.
