Are Stainless Steel Coffee Mugs Safe?

With the ever-increasing risk of health issues, you have to be extra cautious to ensure that the containers you are using to drink from do not contribute to providing any toxins that can be ingested or inhaled. I must admit I have always been mindful in this area. Recently I received a stainless steel coffee mug as a gift. Which left me wondering Are Stainless Steel Coffee Mugs Safe?

According to the US Food and Drug Administration, stainless steel coffee mugs are safe as long as they have at least 16% chromium. It is also vital to ensure that the mug is made of high-quality stainless steel, which will ensure that it is completely BPA and toxin-free.

It is crucial to understand that although stainless steel has been around for many years, having undergone many stringent tests in the manufacturing process, to obtain a stamp of approval, some mugs on the market may resemble the product but differ in quality. Let’s gain more insight on identifying the real from the generic product and explore why stainless steel mugs are safe.

How To Test If The Stainless Steel Is Of Good Quality?

Unless you have personally purchased your stainless steel mug from a reputable stainless steel supplier, you might question the authenticity of your stainless steel mug. It would be advisable to eliminate all doubts and follow the below;

  • Check that the mug has a stainless steel stamp of approval; if it does not, then chances are it is not genuine.
  • Alternatively, you can try the home test of boiling water in the mug with a tablespoon of vinegar for a few minutes; if the boiled water has a metallic taste, it means the steel is reactive and of inferior quality.
  • You can also do the magnet test; if your magnet sticks to the mug, it is stainless steel, which is highly resistant to corrosion; if it does not, it means it contains nickel, a product that can corrode very easily.
