How to Tell What Is (and Isn’t) Dishwasher Safe
Unsure if an item is safe for the dishwasher? The most common way to tell if something is safe for the dishwasher is to check for a corresponding symbol underneath (a plate or glass with water drops above it) or a label that says “dishwasher safe.” Plastics with a low melting point, kitchen-specific glass, and glazed ceramics can all also be placed in the dishwasher. If it can sustain sharp temperature changes, then it’s good to go.
When it comes to deciding what shouldn’t go in a dishwasher, steer clear from items that are not certified “dishwasher safe” (because doing a few dishes by hand never hurt anyone, right?). Generally, you really don’t want to stick in items that are insulated, made from rust-prone metal, wood, or light plastics, or are gold-trimmed in the dishwasher.
