In this comprehensive guide, we’ll explore everything you need to know about how to dishwasher plastic, including the different types of plastic, the proper settings to use, and tips for preventing damage.
Types of Plastic Suitable for Dishwashing
Not all plastics are created equal, and some are not suitable for dishwashing. Here are the most common types of plastic that are safe to put in the dishwasher:
- Polyethylene Terephthalate (PET or PETE): This type of plastic is commonly used for food containers, beverage bottles, and microwavable dishes.
- High-Density Polyethylene (HDPE): HDPE is used for milk jugs, detergent bottles, and cutting boards.
- Polypropylene (PP): PP is found in yogurt containers, margarine tubs, and reusable food storage containers.
- Low-Density Polyethylene (LDPE): LDPE is used for plastic bags, wrapping paper, and squeeze bottles.
Dishwasher Settings for Plastic
When dishwashing plastic, it’s important to use the proper settings to avoid damage. Here are the recommended settings:
- Water Temperature: Use warm or hot water, but avoid using excessively hot water as it can warp or melt the plastic.
- Cycle: Choose a gentle or delicate cycle with a low or no-heat dry setting.
- Detergent: Use a mild dishwashing detergent specifically designed for plastic.
Tips for Preventing Damage
To prevent damage to your plastic items during dishwashing, follow these tips:
- Check the Labels: Always check the labels on plastic items to ensure they are dishwasher safe.
- Avoid Overcrowding: Don’t overcrowd the dishwasher, as this can prevent water and detergent from reaching all surfaces of the plastic.
- Use a Mesh Bag: For small plastic items, use a mesh bag to prevent them from falling through the racks.
- Place Plastic on the Top Rack: The top rack is generally cooler than the bottom rack, which helps prevent warping and melting.
- Avoid Using Harsh Detergents: Harsh detergents can damage plastic over time.
- Inspect Plastic After Washing: After dishwashing, inspect plastic items for any signs of damage, such as cracks or discoloration.
Special Considerations for Certain Types of Plastic
Some types of plastic require special considerations when dishwashing:
- Polycarbonate: Polycarbonate should be washed in the top rack and avoid using harsh detergents.
- Acrylic: Acrylic can scratch easily, so use a soft sponge and avoid using abrasive detergents.
- Melamine: Melamine is not dishwasher safe and should be hand-washed only.
Troubleshooting Common Issues
If you encounter any issues when dishwashing plastic, here are some troubleshooting tips:
- Plastic Melted or Warped: This can occur if the water temperature was too high or the cycle was too harsh. Adjust the settings accordingly.
- Plastic Became Discolored: This can be caused by using harsh detergents or washing plastic with food stains. Use a mild detergent and try soaking the plastic in a solution of baking soda and water.
- Plastic Has a Chemical Odor: This can occur if the plastic is not dishwasher safe or if the detergent was too strong. Wash the plastic again using a mild detergent and check the label to ensure it is dishwasher safe.
