The answer to whether plastic cutlery can be put in the dishwasher depends on the type of plastic used to make it. While polypropylene cutlery is generally dishwasher safe, polystyrene and PLA cutlery may not fare well in the dishwasher. Let’s examine each type in detail.
Polypropylene Cutlery: As mentioned earlier, polypropylene is a durable plastic that can withstand high temperatures without melting or warping. Therefore, it is safe to put polypropylene cutlery in the dishwasher. However, it’s advisable to place them on the top rack to prevent any potential exposure to heating elements or high-pressure water.
Polystyrene Cutlery: Polystyrene, being a less heat-resistant plastic, should not be put in the dishwasher. The high temperatures and aggressive spray action in the dishwasher can cause the cutlery to melt, deform, or release toxic substances. It is best to wash polystyrene cutlery by hand.
Polylactic Acid (PLA) Cutlery: PLA cutlery, like polystyrene, is also not dishwasher safe. The lower heat tolerance of PLA makes it susceptible to warping and deformation. It is recommended to wash PLA cutlery by hand to maintain its shape and prevent any potential harm.
Tips for Dishwashing Plastic Cutlery
If you have determined that your plastic cutlery is dishwasher safe, there are a few precautions and tips to keep in mind:
- Use the top rack: To protect your plastic cutlery from the intense heat and water pressure found in the lower part of the dishwasher, always place them in the top rack.
- Avoid high temperatures: Even if your plastic cutlery is dishwasher safe, it’s best to select a lower temperature setting on your dishwasher. This will help prevent any potential damage, especially to less heat-resistant varieties.
- Use gentle detergents: Harsh detergents can cause damage to plastic cutlery, including fading or pitting. Opt for mild and eco-friendly detergents to ensure the longevity of your utensils.
- Rinse off food particles: Before placing plastic cutlery in the dishwasher, make sure to rinse off any excessive food particles. This will prevent any clogging or damage to the dishwasher mechanism.
The suitability of plastic cutlery for dishwasher use depends on the type of plastic it is made from. While polypropylene cutlery is generally dishwasher safe, polystyrene and PLA should be washed by hand to avoid deformation or damage. Always check the manufacturer’s instructions or packaging for specific care recommendations. By following proper guidelines and using gentle settings, you can effectively clean your plastic cutlery and ensure its longevity.
