Description Milfoam Forrest Foam is designed for quick, efficient gun barrel cleaning and tackling copper fouling, carbon buildup, and gunpowder residue.  With its 360-degree cleaning system, it delivers full barrel coverage, making cleaning faster and more effective than traditional methods. The foam’s colour-changing formula turns blue for copper and black for other residues, ensuring you know exactly when cleaning is complete.  Non-toxic and ammonia-free, it provides a safe, damage-free clean while maintaining your barrel’s performance. How to Use: Apply the foam, wait 15–30 minutes, then wipe clean. For stubborn fouling, repeat until the foam turns white.
