I tested it on a 316 sink and it showed 316. On a 304 it didn't. But it will definitely etch, so only use it on an inconspicuous area. ### ⭐⭐⭐⭐ Small...works *by on Reviewed in the United States April 5, 2026* Very small but it does work ### ⭐⭐⭐ It may work, but highly overpriced for the quantity actually received. *by on Reviewed in the United States August 7, 2026* I understood from the description that these would be small bottles. What I didn’t know was that one of the bottles would barely be 1/2 full and the other bottle would be 1/4 full. I’m not sure if it’s a quality control issue or what. But be aware. ## Frequently Bought Together - Stainless Steel Test Kit for Differentiating 316/304 [Packaging Upgraded 2025] - DIYMAG Super Strong Neodymium Fishing Magnets, 500 lbs(227 KG) Pulling Force Rare Earth Magnet with Countersunk Hole Eyebolt for Retrieving in River and Magnetic Fishing,Diameter 2.36 inch(60 mm) --- ## 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.ma/products/577383394-stainless-steel-test-kit-for-differentiating-316-304-packaging-upgraded](https://www.desertcart.ma/products/577383394-stainless-steel-test-kit-for-differentiating-316-304-packaging-upgraded) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-08-15*
