It is not uncommon to see tarnishing sometimes, it can be casued by detergents not being washed off correctly, contact with hot fat, contact with vinegar, wine and even foods that are high in acidity. Tarnishing can sometimes be remedied using the dishwasher instructions, or easily removed with a proprietary stainless steel cleaning cream (we recommend Bar Keepers Friend).
When using a dishwasher, we recommend:
Wash on a short hot cycle (65°-75°).
Use quality branded ***all in one*** dishwasher tablets*.
Keep Rinse Aid topped up and Salt (for hard water areas).
Avoid washing with non-stainless steel metals (these can cause rust staining - especially on knives).
Ensure the dishwasher filters are cleaned and use a proprietary dishwasher cleaner regularly.
Always avoid scouring your stainless steel product with pads or abrasive cleaners as this will scratch the surface.
Do not place products with plastic or wooden parts or black EVA bases in the dishwasher!
*For UK customers we recommend Fairy Platinum Plus and for US customers Cascade Platinum Plus
