What is the symbol for dishwasher safe?
People often confuse the cup and fork symbol for the dishwasher safe symbol. The thing is that there is not universally approved symbol for dishwasher safe. The cup and fork means that the material is safe for food use.
The international symbol for "food safe" material is a wine glass and a fork symbol. The symbol identifies that the material used in the product is safe for food contact. This includes food and water containers, packaging materials, cutlery etc.
- Lock & Lock Glass. Lock&Lock Glass containers, the original oven safe containers, are essentiel when it comes to storing, re-heating or even cooking your food. Each piece (container and lid) is freezer, dishwasher and microwave safe.
- The primary use of microwaves in a kitchen oven is to heat water molecules. Porcelain is fired at very high temperatures - many times the boiling point of water. That means there will not be any water internal to the porcelain. So it should be OK to put porcelain in a microwave oven.
- If you choose to use plastics, stick with those labeled “microwave-safe” (but don't allow plastic wrap to touch your food during heating). If you're wary, use glass or ceramic dishes marked “heatproof” or “microwave-safe.”
Most takeout containers, water bottles, and plastic tubs or jars made to hold margarine, yogurt, whipped topping, and foods such as cream cheese, mayonnaise, and mustard are not microwave-safe. Microwavable takeout dinner trays are formulated for one-time use only and will say so on the package.

- Not all glass is designed to be used in the microwave, so stick to products labeled "microwave safe." If the glassware isn't labeled, check by microwaving the container on high for a minute or two and give it a quick feel. A slightly warm or cool glass is microwave safe.
- All Ziploc® brand Containers and microwavable Ziploc® brand Bags meet the safety requirements of the U.S. Food and Drug Administration (FDA) for temperatures associated with defrosting and reheating food in microwave ovens, as well as room, refrigerator and freezer temperatures.
