While the dishwasher safe symbol is helpful, understanding the type of plastic is equally important. Different types of plastic have varying tolerance levels to heat and detergents.
Common Types of Plastic Used in Dishware
Polypropylene (PP): Often labeled with the number 5 for recycling, polypropylene is durable and typically dishwasher safe. It can withstand high temperatures without losing its shape.
Polyethylene (PE): With recycling numbers ranging from 1 to 4, polyethylene is more sensitive to heat compared to polypropylene. Not all variants are dishwasher safe.
Acrylic: Acrylic dishes are lightweight and stylish but can scratch easily. While some brands may label acrylic as dishwasher safe, it’s best to wash them on the top rack to minimize exposure to heat.
Not Dishwasher Safe
Conversely, there are some types of plastic that should never go in the dishwasher. These include:
Polystyrene (PS): Often found in disposable cups and food containers, polystyrene can warp and leach chemicals when heated.
PVC (Polyvinyl Chloride): Common in cling wrap, PVC does not fare well in a dishwasher and shouldn’t be exposed to high temperatures.
How the Dishwasher Works
Understanding how a dishwasher operates can give you insight into why certain materials are labeled as dishwasher safe.
Dishwasher Mechanics
Water Temperature: Dishwashers use water heated typically between 130°F to 170°F (54°C to 77°C) for effective cleaning. This high temperature is often necessary to dissolve grease and food residues.
Water Pressure: Dishwashers spray water at a high pressure to dislodge food particles. This intense spraying can be detrimental to certain materials.
Detergents: Powerful detergents are used, which can contain enzymes that are effective against food stains but may be harsh on certain types of plastic.
Testing for Safety
Items that carry the dishwasher safe symbol have been subject to testing, which typically includes:
- Temperature Testing: Products are subjected to various temperatures to see how they react.
- Chemical Resistance Testing: Products are also exposed to different detergents to ensure they remain unchanged under standard dishwasher conditions.
Best Practices for Using Plastic in the Dishwasher
While understanding the dishwasher safe symbol is critical, following best practices for cleaning plastic items can further extend their lifespan.
Tips for Cleaning Plastic in the Dishwasher
Top Rack Only: If the item specifies “Top Rack Only,” always follow this guideline. The top rack is furthest from the heating element, minimizing exposure to high temperatures.
Avoid the Heated Dry Cycle: If you’re concerned about certain plastics warping, you may want to skip the heated dry cycle and opt for air drying instead.
Regular Maintenance
Proper maintenance of your dishwasher is also crucial. Build-up from food particles and detergent can affect cleaning effectiveness. Follow these steps for optimal performance:
Clean the Filter: Most dishwashers have a filter that can trap food particles. Clean it regularly to ensure efficient drainage and cleaning.
Run Hot Water Before Loading: Running hot water at your sink before starting your dishwasher can help maintain higher starting temperatures for the cleaning cycle.
Environmental Considerations
Understanding the dishwasher safe symbol also has environmental implications. Not all plastics are recyclable, and improper washing may result in items needing to be replaced more frequently.
Sustainable Practices
Choose Quality Over Quantity: Invest in high-quality, durable plastic wares that offer a dishwasher safe label.
Reduce Single-Use Plastics: Opt for reusable and dishwasher-safe items to minimize waste and contribute to environmental sustainability.
