Rust stains on forks and knives are annoying, especially if you bought stainless steel cutlery. As a matter of fact, the rust stains often appear when we don't treat the cutlery in the right way. For example, it happens when we wash it in the dishwasher together with items that are not suitable for dishwasher. When you wash items made of iron in the dishwasher small iron particles are being released and can cause rust stains on stainless steel, so-called flash rust.
Items made of iron should not be washed in the dishwasher. Here are some of the most common items that cause flash rust:
If cutlery or other stainless steel items are exposed to fruit acid, acetic acid, lactic acid or salt for a long time, the acid will corrode the stainless steel surface. In this way, the rust can spread and become difficult to get rid of. Don't leave the cutlery in the sink for a long time. Rinse and place it in the dishwasher immediately after use.
