Dishwasher Safe Symbols:
Most plastic bowls and containers have symbols or labels on their base indicating whether they are dishwasher safe. These symbols help users understand the compatibility of the plastic with dishwasher cycles. Typical symbols include a wine glass and water droplets or a plate with water droplets. It is crucial to recognize and adhere to these symbols to ensure the longevity and safety of your plastic bowls.
Heat Resistance of Different Plastics:
Different types of plastics possess varying levels of heat resistance. Here are some common plastics and their dishwasher compatibility:
- Polypropylene (PP): This plastic is highly heat resistant and typically labeled dishwasher safe.
- High-Density Polyethylene (HDPE): HDPE is another plastic that generally withstands dishwasher cycles well.
- Polystyrene (PS): Polystyrene can be dishwasher safe, but it is advisable to check for specific labels indicating compatibility.
- Polyethylene Terephthalate (PET or PETE): PET is commonly used in water and soda bottles and is generally dishwasher safe.
- Polyvinyl Chloride (PVC): PVC plastics tend to be dishwasher safe, but it is crucial to verify this information before placing them in your dishwasher.
- Other plastics: Various other plastics may not be dishwasher safe, such as low-density polyethylene (LDPE), which can warp or melt under hot water conditions.
Factors to Consider:
Apart from the type of plastic, several other factors should be taken into account when deciding whether to place plastic bowls in the dishwasher. These factors include the quality and thickness of the plastic, the age and condition of the plastic, as well as the dishwasher’s temperature settings.
Tips for Dishwashing Plastic Bowls:
If you are unsure about a plastic bowl’s dishwasher compatibility or it lacks a dishwasher safe symbol, consider the following tips:
- Handwashing as a safer alternative: When in doubt, it is generally recommended to handwash plastic bowls to avoid any potential damage or release of harmful chemicals.
- Precautions for placing plastic bowls in the dishwasher: Ensure that the dishwasher’s temperature settings are not too high, as excessive heat can lead to warping, melting, or leaching of toxins.
- The top rack is usually recommended: Placing plastic bowls on the top rack is often suggested, as the bottom rack is closer to the heating element and may subject the plastic to higher temperatures.
The answer to whether plastic bowls can be placed in the dishwasher largely depends on several factors, including the type of plastic, dishwasher safe symbols, and individual considerations such as plastic quality and dishwasher settings. To ensure the safety and longevity of your plastic bowls, it is best to follow manufacturer guidelines, consider handwashing as a safer alternative, and be cautious when placing plastic in the dishwasher.
