- Before using your colanders for the first time, hand-wash with warm soapy water. Rinse and dry thoroughly. - Do not leave or store food remains in the colanders for long periods of time. Superficial pitting may occur if very salty or acidic foods (such as tomatoes) are left in the colanders. - The colanders are not suitable for stove-top, oven or microwave use. - Stainless steel colanders are dishwasher-safe. However, we recommend hand-drying the colanders immediately after the rinse cycle or hand-washing and drying to prevent water spots from forming. - To recondition your colanders or to remove stubborn spots or stains, use a nonabrasive pad and quality stainless steel cleanser such as Bar Keepers Friend®.
