| Try the following: Mix some white vinegar with pure lemon juice and scrub the pan interiors with a non abrasive cloth. The spots are probably scale deposits from the dishwashing detergent. Some detergents have a high PH level which can spot stainless steel. In some cases salt will cause pitting or white spots, although that doesn't sound like what you're experiencing. Couple tips to keep in mind. Add salt after water is boiling!!! Not before. Also, allow your stainless cookware to pre-heat over medium low heat for a few minutes before adding oil. And as a last step, salt your food before it goes in the pan, not after. Finally, I know the line is dishwasher safe. But you've made a substantial investment in quality cookware. Always wash by hand when you can. |
