Whether you can put plastic mixing bowls in the dishwasher depends on the type of plastic they are made from and whether they are labeled as dishwasher safe. Here are some guidelines to help you determine if your plastic mixing bowls can go in the dishwasher:
Check the Label: Look for any labels or symbols on the bottom or side of the mixing bowls that indicate whether they are dishwasher safe. If the bowls are labeled as "Dishwasher Safe" or have a dishwasher-safe symbol (usually a plate or glass with water droplets), you can safely put them in the dishwasher.
Inspect the Resin Identification Code (RIC): Most plastic items have a recycling symbol with a number inside. This number represents the Resin Identification Code (RIC), indicating the type of plastic used. As a general guideline, plastic mixing bowls with RIC numbers 1, 2, 4, and 5 are usually dishwasher safe. These plastics are considered more heat-resistant and less likely to warp or release harmful chemicals when exposed to the dishwasher's heat and detergents.
- RIC #1: PET or PETE (polyethylene terephthalate) - Usually dishwasher safe.
- RIC #2: HDPE (high-density polyethylene) - Generally dishwasher safe.
- RIC #4: LDPE (low-density polyethylene) - Usually dishwasher safe.
- RIC #5: PP (polypropylene) - Generally dishwasher safe.
Temperature Considerations: While some plastic mixing bowls are dishwasher safe, it's essential to check the manufacturer's recommended temperature limits. Some plastic materials can withstand the dishwasher's heat, while others may warp or become damaged.
Top Rack Placement: If your plastic mixing bowls are dishwasher safe, it's best to place them on the top rack of the dishwasher. The top rack is further away from the dishwasher's heating element, reducing the risk of warping or melting.
Old or Worn Plastic Bowls: If your plastic mixing bowls are old, scratched, or worn, it's generally safer to wash them by hand. Older plastic can become more brittle and may not handle the dishwasher's heat and water pressure as well as newer items.
Always refer to the manufacturer's instructions or packaging for specific dishwasher safety guidelines for your plastic mixing bowls. If you're unsure about whether they are dishwasher safe, it's best to wash them by hand using warm, soapy water to avoid any potential damage.
