Key Details at a Glance
Product: Sweet’s 7.62 Bore Cleaner
Function: Copper fouling remover (not a carbon solvent)
Formulation: Ammonia-based; designed for steel barrels when used as directed
Recommended Tools: Nylon bore brush or patch jag, quality cotton patches, bore guide
UPC: 797776593804
Note: Avoid contact with bronze/brass brushes (ammonia can attack copper alloys) and with stock finishes or painted surfaces.
How to Use (Step-by-Step)
Make Safe & Prep: Ensure the firearm is unloaded. Use a bore guide to protect the throat and keep solvent out of the action.
Wet the Bore: Soak a clean patch with Sweet’s 7.62 and push from chamber to muzzle in one smooth pass. Do not pull a dirty patch back through the bore.
Let It Work (Short Dwell): Allow 5–10 minutes of contact time. Do not exceed the manufacturer’s maximum recommended dwell (commonly no more than 15 minutes per cycle).
Patch Out: Push dry patches until they come out light blue to clear. The blue color indicates dissolved copper.
Repeat if Needed: For heavy fouling, repeat steps 2–4. Keep each dwell time short.
Neutralize & Protect: After copper is removed, follow with a neutral carbon solvent or alcohol patch, then apply a light oil to protect the bore.
Pro Tips for Best Results
Use Nylon, Not Bronze: Choose a nylon brush to avoid false indications and to prevent brush damage.
Carbon First, Copper Second: Remove carbon fouling with your preferred carbon solvent before applying Sweet’s—this exposes copper for faster action.
Short, Smart Contact: Multiple short sessions beat one long soak. Avoid letting solvent dry in the bore.
Ventilation Matters: Strong, effective chemistry—work in a well-ventilated area and wear gloves/eye protection.
Store Wisely: Keep the cap tight; store upright, away from heat and stock finishes.
Safety & Compatibility
Safe for Steel Bores when used as directed.
Avoid prolonged contact with nickel plating, aluminum, anodized parts, wood finishes, and painted surfaces. Wipe any accidental contact immediately.
Do not mix with chlorine bleach or other household chemicals.
Always finish with a neutral cleaner and light oil to protect steel from flash rust.
Frequently Asked Questions
Q: Will Sweet’s 7.62 remove carbon?
A: It’s formulated for copper, not carbon. Use a dedicated carbon/lead solvent first, then follow with Sweet’s to attack copper.
Q: Can I leave it in overnight?
A: No. Keep contact times short (5–10 minutes, max ~15) per cycle. Multiple short cycles are safer and more effective.
Q: Why are my patches blue?
A: That’s copper being dissolved—blue/green indicates copper ions lifted from the bore.
Q: Is it safe for stainless barrels?
A: Yes, when used as directed—short dwell, thorough patch-out, then neutralize and oil.
Q: What brush should I use?
A: Nylon only. Ammonia can chemically attack bronze/brass brushes.
Use Cases
Precision Rifles: Long-range rigs that shoot jacketed bullets and demand consistency.
Hunting Rifles: Seasonal deep cleans before/after hunts to maintain cold-bore predictability.
Service & Training Guns: High round-count barrels that accumulate copper quickly.
Competition Prep: Copper control between stages or match days to keep groups tight.
