Wait a few seconds and observe the color change. Compare the resulting color to the indicator chart printed on the bottle to identify the steel grade (200, 201, 202, 301, or 304\/316).\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this testing liquid distinguish between 304 and 316 stainless steel grades?\u003c\/h4\u003e\n\u003cp\u003eA: This testing liquid primarily identifies steel grades based on manganese content, which effectively differentiates lower-grade 200-series steels from higher-grade 300-series (such as 304\/316). For a more precise 304 vs. 316 distinction, additional molybdenum-specific testing may be required.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this product safe to use at home to test kitchenware and tableware?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — it is designed for both home and professional use. However, as with any chemical testing solution, always handle it with care, avoid contact with skin and eyes, keep it away from children, and ensure adequate ventilation. Follow all safety precautions listed on the bottle label.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many tests can I get from a 12ml bottle?\u003c\/h4\u003e\n\u003cp\u003eA: Because only a single drop is needed per test, a 12ml bottle provides a large number of tests — typically hundreds — making it highly economical for both occasional home use and frequent professional quality control checks.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"How do I use the stainless steel grade testing liquid?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Simply apply one single drop of the testing liquid to a clean surface of the stainless steel item you want to test.
