Introduction
Plastic containers have become a staple in our kitchens for storing and reheating leftovers. However, many people are unsure whether these containers are safe to use in the dishwasher. In this article, we will explore whether plastic containers are dishwasher safe and provide some tips for safely cleaning them.
What Does “Dishwasher Safe” Mean?
When a plastic container is labeled as “dishwasher safe,” it means that it has undergone specific testing to ensure it can withstand the high temperatures and water pressure of a dishwasher cycle without warping or releasing harmful chemicals.
Understanding Different Types of Plastics
Not all plastics are created equal, and their ability to withstand dishwasher cycles varies. It’s important to familiarize yourself with the different types of plastics commonly used in food containers:
1. Polyethylene Terephthalate (PET)
PET is a commonly used plastic for water and soda bottles. It is generally not dishwasher safe and can release harmful chemicals when exposed to high temperatures.
2. High-Density Polyethylene (HDPE)
HDPE is a sturdy plastic used in milk jugs, detergent bottles, and some food containers. It is dishwasher safe and does not release harmful chemicals when exposed to heat.
3. Polyvinyl Chloride (PVC)
PVC is a flexible plastic commonly used in cling wraps and some food containers. It is not dishwasher safe and can release harmful chemicals when exposed to heat.
4. Low-Density Polyethylene (LDPE)
LDPE is a flexible plastic used in squeeze bottles and food storage bags. It is dishwasher safe and does not release harmful chemicals when exposed to heat.
5. Polypropylene (PP)
PP is a durable plastic commonly used in microwave-safe food containers. It is dishwasher safe and does not release harmful chemicals when exposed to heat.
6. Polystyrene (PS)
Polystyrene is a rigid plastic used in disposable food containers and foam packaging. It is not dishwasher safe and can release harmful chemicals when exposed to heat.
How to Determine If a Plastic Container Is Dishwasher Safe
Most plastic containers will have a label indicating whether they are dishwasher safe. Look for phrases like “top-rack dishwasher safe” or “dishwasher safe” on the packaging. If there is no label, check the manufacturer’s website or contact their customer service for information.
Tips for Safely Cleaning Plastic Containers
If a plastic container is labeled as dishwasher safe, follow these tips to ensure proper cleaning:
1. Use the top rack:
Place the plastic containers on the top rack of the dishwasher to minimize exposure to direct heat.
2. Avoid high heat settings:
Set your dishwasher to a lower temperature or a gentle cycle to prevent warping or melting of the plastic.
3. Skip the heated dry option:
Avoid using the heated dry option, as it can subject the plastic to prolonged exposure to heat.
4. Hand wash if unsure:
If a plastic container is not labeled as dishwasher safe or you are unsure about its material, it is best to wash it by hand using warm, soapy water.
Conclusion
While some plastic containers are dishwasher safe, not all plastics can withstand the high temperatures and water pressure of a dishwasher cycle. It is essential to check the labeling or contact the manufacturer for specific information on a particular plastic container. When in doubt, it is always safer to hand wash the container to avoid any potential harm. Remember, proper care and maintenance will ensure the longevity of your plastic containers and keep your food storage safe.
