Grayish Residue in Bottom of Bowl - Stand Mixer

Possible Solutions

How to remove residue from the stainless bowl?

  1. Put a small amount of olive oil in the bowl and spread it around inside the bowl.
  2. Let this sit for several minutes, then wipe the oil out.
  3. After removing the oil, wash the bowl with hot water and good dish detergent.

Or, use a mixture of lemon juice and salt, or a baking soda paste to clean the bowl. These are food-safe alternatives with abrasive qualities that will adequately clean the bowl.

How did the residue get there?

A mechanical only polishing process is used in stainless steel bowls to make them shiny.  There is no polish involved.

Occasionally, new stand mixer bowls may have residue in the bowl that cannot be removed in the dishwasher or by hand washing. When this happens, it may be noticeable to the naked eye. This residue is not harmful, and it can be removed easily.  It can discolor food items mixed in the bowl.  It is a common occurrence when polishing stainless products.
