I have tried it and that is what happens. In a water pipe it is fine as it all washes away naturally. **Q: I have a ring that snapped and i want to fix it, i can still wear the ring but the part where it snapped pinches the skin. can i use it on jewelry?** A: This would likely corrode the ring badly. Its removes oxidized layers so solder can stick to the base metal. It's very acidic and corrosive. ## Frequently Bought Together - LA-CO 22194 -Water Soluble, All Weather Copper Flux Paste for Soldering, Brush in Cap, Developed for Plumbing, 4 oz, Made in USA - AIM Lead-Free Plumbing Solder, Silver Bearing, 0.125inch dia, 1/2 Lb Spool - Pro Grade - Acid Brushes - 36 Count 3/8 Inch Boar Hair Acid Flux Brushes --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/61297208-la-co-22194-water-soluble-all-weather-copper-flux-paste](https://www.desertcart.sn/products/61297208-la-co-22194-water-soluble-all-weather-copper-flux-paste) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-22*
