Stains on Stainless Steel or Silver After Wash

Cause:

  • Some food remnants such as mustard, mayo, lemon, vinegar, salt, and dressings can cause stains on stainless steel or silver if they remain on the silverware.
  • Aluminum can also cause stains on dishes.
  • Stainless steel can cause staining on silver

Topics:

  • Silverware has stains on it after running the dishwasher
  • Knives, forks or spoons are dirty after washing
  • Rust or Rouging on stainless steel after washing

Steps to Verify Issue:

  1. Rinse all food residue if the dishwasher will not run immediately.
  2. Separate cutlery into various compartments in the basket.
  3. Ensure silver and stainless steel are not together.

Answer:

If stains are appearing on stainless steel or silver after washing, check the following:

  • Use longer dry features and rinse aid to ensure all the dishes are completely dry.
  • Run the dishwasher regularly since discoloration of cutlery can occur if flatware is left in the diswasher too long and moisture on untensils can cause stainless steel to rust.
  • Hard water and using more detergent can cause problems with the detergent not rinsing fully.
    • Detergent residue staying on utensils can cause discoloration.
  • Do not mix stainless steel with non-stainless steel as it can cause spots that appear like rust, this is called rouging.
