Yes. All of our products are dishwasher safe. There are many reasons why some stainless steel products are hand wash only, or "not recommended" for the dishwasher. It may be to protect the exterior paint finish, to protect the chemical resins that leach when heated, or it may be because of the interior seam that weakens with heat. It could be because of the non-dishwasher safe parts such as the clasps, lids, seals, straws. We wanted safe, but we also wanted simple, so go ahead and drop them in the dishwasher!
Refrigerator- Yes. The containers are excellent for storing all types of food, including the most fragrant or acidic foods. No more tomato stains or lingering food odors from traditional containers. Microwave- No. These are metal product and should never be used in a microwave. They can, however, go in an oven up to 450 degrees F. You'll likely want to reheat at about 350degrees. Unlike glass or ceramic, stainless steel heats up rapidly.
Yes, the containers can go in the freezer and are great for storing all types of food. For kids at school or even for work, freezing yogurt in a DALCINI™ Stainless container can work as a cold pack for the rest of your lunch and ensure your yogurt stays cold. Do not over fill.
