Using your Passage bowl is a breeze. Just put your food in it, and the Cool Grip fins will let you hold it without worrying about burning your hands. When it comes to cleaning, you can simply wash it with warm soapy water. It's also dishwasher - safe, but make sure to place it in a secure position to avoid any bumps. Since it's microwave - safe, you can heat up your leftovers right in the bowl. However, always use caution when taking it out of the microwave as it can get hot. Store it in a dry place to keep it in good condition, and it'll serve you well for a long time.
