Stainless steel is a metal made of iron, chromium and nickel which makes it strong and resistant to corrosion. Not all steels are the same and here at Cheeki we use a high quality, food grade 304 stainless steel. 304 is the grading of the nickel and chromium and in the food industry it is also referred to as 18/8 grade.

By not going into too much scientific details but to be graded as “food grade” the steel must be resistance to corrosion, less thermally conductive (transferring of heat) and finally being very durable. One of the most important things of our steel is that it’s super smooth. This prevents any bacteria to grow on the surface of the metal. Unlike other materials like plastic germs can make their homes in little scratches and grooves on the surface.

So, in summary. We use high quality food grade stainless steel that’s durable and safe. Free from BPA, toxins and lead. So ditch the plastic and use Cheeki stainless steel for all your refill and reuse needs.
