Although the stainless steel cup is durable, rust-proof, corrosion-proof, durable and beautiful, it belongs to alloy products and contains a lot of heavy metal substances, such as nickel, chromium and manganese. These heavy metals can be released easily if they are not used properly, which is harmful to health.
Therefore, you can't use stainless steel cups to hold acidic drinks, soy sauce, vinegar, vegetable soup, tea and so on. After a long time, otherwise the electrolyte in these foods will react with the heavy metals in stainless steel, leading to the precipitation of heavy metals.
