When it comes to loading the dishwasher, we’ve all been guilty of tossing in that one plastic item that we’re not quite sure is dishwasher safe. Maybe it’s a leftover container from last night’s takeout or a favorite plastic cup that we just can’t resist washing. But before you hit that start button, stop and think about the potential consequences of putting non-dishwasher safe plastic in the dishwasher.
The Risks of Washing Non-Dishwasher Safe Plastic
Deformation and Warping
One of the most obvious risks of washing non-dishwasher safe plastic is deformation and warping. The high heat and harsh detergents in the dishwasher can cause plastic to melt, bend, or warp, rendering it useless. This is especially true for plastic items with raised patterns or intricate designs, as the heat can cause them to lose their shape and become misshapen.
For example, if you put a non-dishwasher safe plastic cup in the dishwasher, it may come out looking like a sad, melted version of its former self. Not only is this aesthetically unappealing, but it can also make the cup unusable.
Harm to the Dishwasher
But it’s not just the plastic item that’s at risk – the dishwasher itself can also be damaged by washing non-dishwasher safe plastic. The melted or deformed plastic can clog the dishwasher’s filters and pipes, leading to costly repairs or even causing the dishwasher to break down altogether.
Clogged Filters
If melted plastic debris accumulates in the dishwasher’s filters, it can cause them to become clogged. This can lead to poor wash performance, bad odors, and even cause the dishwasher to overflow. In severe cases, clogged filters can even cause the dishwasher to break down, requiring expensive repairs.
Pipes and Pumps
Worse still, melted plastic can also damage the dishwasher’s pipes and pumps. As the plastic melts, it can flow into the pipes and pumps, causing blockages and damage to the internal mechanisms. This can lead to a range of problems, from poor wash performance to complete breakdown of the dishwasher.
Melted Plastic and the Environment
Microplastics in Waterways
When non-dishwasher safe plastic is washed in the dishwasher, it can break down into microplastics – tiny plastic particles that are smaller than 5 millimeters in size. These microplastics can then be released into waterways through wastewater, where they can harm aquatic life and contaminate the food chain.
Microplastics have been found in everything from drinking water to table salt, and have even been linked to the ingestion of plastic by humans. By washing non-dishwasher safe plastic in the dishwasher, we’re contributing to this growing environmental problem.
The Impact on Marine Life
Microplastics can have devastating effects on marine life. Many marine animals mistake microplastics for food, ingesting them and causing blockages, nutrient deficiencies, and even death. In addition, microplastics can leach toxic chemicals into the water, further harming marine life.
The Human Impact
But it’s not just marine life that’s affected by microplastics – humans are also at risk. When we ingest microplastics through contaminated food and water, we’re exposing ourselves to a range of potential health risks. While the exact impact of microplastics on human health is still unknown, it’s clear that it’s a risk we shouldn’t be taking.
How to Check If a Plastic Item is Dishwasher Safe
So, how can you avoid the risks of washing non-dishwasher safe plastic in the dishwasher? Here are a few simple steps to follow:
Check the Label
The first step is to check the label on the plastic item. Most manufacturers will indicate whether an item is dishwasher safe or not. Look for a symbol that resembles a box with dishes inside, or a statement that explicitly says “dishwasher safe”.
Check the Material
If there’s no label, you can try checking the material the plastic item is made of. Some plastics, like polycarbonate and polypropylene, are generally dishwasher safe. However, others, like acrylic and polystyrene, are more likely to be damaged by the dishwasher.
Consult the Manufacturer
If you’re still unsure, consult the manufacturer’s instructions or contact their customer service department. They can provide guidance on whether the plastic item is safe to wash in the dishwasher.
Conclusion
Washing non-dishwasher safe plastic in the dishwasher can have serious consequences, from deformation and warping to damage to the dishwasher itself. Moreover, it can contribute to the growing environmental problem of microplastics in waterways. By taking a few simple steps to check if a plastic item is dishwasher safe, we can avoid these risks and keep our dishwashers, our plastic items, and our planet safe.
Remember, it’s always better to err on the side of caution when it comes to washing plastic items. If in doubt, hand wash or avoid washing the item altogether. The few extra minutes of effort are worth it to avoid the potential consequences of washing non-dishwasher safe plastic in the dishwasher.
What happens if I put a non-dishwasher safe plastic item in the dishwasher?
If you put a non-dishwasher safe plastic item in the dishwasher, it can cause serious damage to the item itself and potentially to your dishwasher as well. The high heat and harsh detergents in the dishwasher can cause the plastic to warp, crack, or break down completely. This can lead to a mess of melted plastic and soap residue in your dishwasher, which can be difficult and time-consuming to clean.
In addition to damaging the plastic item, using a non-dishwasher safe plastic in the dishwasher can also cause problems with your dishwasher’s performance. The broken down plastic particles can clog the dishwasher’s filters and pipes, leading to poor washing performance and potentially even causing the dishwasher to break down.
How can I tell if a plastic item is dishwasher safe?
Check the manufacturer’s labels and instructions that came with the plastic item. Most manufacturers will clearly indicate whether an item is safe for use in the dishwasher. Look for a dishwasher safe symbol, which is usually a picture of a plate with a fork and glass above it, or a label that specifically states “dishwasher safe.” You can also check the manufacturer’s website or contact their customer service department if you’re unsure.
It’s also a good idea to use your own judgment and common sense. If the plastic item is thin, flexible, or has a lot of intricate details, it’s probably not safe for the dishwasher. Delicate or decorative plastic items should always be hand washed to avoid damaging them.
What types of plastic are usually not dishwasher safe?
There are several types of plastic that are usually not safe for use in the dishwasher. These include thin, flexible plastics like those used in storage containers or bags, as well as decorative or ornate plastics that have intricate details or paint. Plastics with wooden or bamboo handles or inserts are also not safe for the dishwasher, as the high heat can cause the wood or bamboo to crack or split.
In general, it’s best to err on the side of caution when it comes to putting plastic items in the dishwasher. If you’re unsure whether an item is safe, it’s always better to hand wash it to avoid damaging it or causing problems with your dishwasher.
Can I put a non-dishwasher safe plastic item on the top rack of the dishwasher?
Even if you put a non-dishwasher safe plastic item on the top rack of the dishwasher, it’s still not a good idea. The top rack is exposed to the same high heat and harsh detergents as the rest of the dishwasher, and can still cause damage to the plastic item. The top rack is not a “safe zone” for non-dishwasher safe plastics, and you should still avoid putting these items in the dishwasher altogether.
In addition, even if the plastic item itself is not damaged, it can still cause problems with your dishwasher. The broken down plastic particles can still clog the filters and pipes, and cause performance issues with your dishwasher.
How do I clean a non-dishwasher safe plastic item?
To clean a non-dishwasher safe plastic item, wash it by hand in warm soapy water. Use a soft sponge or cloth to gently scrub away any food residue or stains, and rinse the item thoroughly with clean water. Avoid using abrasive cleaners or scouring pads, as these can scratch or damage the plastic.
It’s also a good idea to dry the plastic item thoroughly after washing to prevent water spots or bacterial growth. You can use a clean towel to dry the item, or let it air dry.
Can I put a non-dishwasher safe plastic item in the dishwasher if I use a gentle cycle?
Even if you use a gentle cycle, it’s still not a good idea to put a non-dishwasher safe plastic item in the dishwasher. The gentle cycle is designed for delicate items that are specifically labeled as dishwasher safe, and may not provide the same level of protection for non-dishwasher safe plastics.
In addition, the gentle cycle may not remove food residue and stains as effectively as a hand wash, which can leave the plastic item dirty and potentially causing bacterial growth. It’s always best to err on the side of caution and hand wash non-dishwasher safe plastic items to ensure they are cleaned safely and effectively.
What should I do if I accidentally put a non-dishwasher safe plastic item in the dishwasher?
If you accidentally put a non-dishwasher safe plastic item in the dishwasher, stop the cycle as soon as possible and remove the item. Check the item for any signs of damage, such as warping, cracking, or breaking. If the item is damaged, it’s best to discard it to avoid any potential harm or safety risks.
If the item appears to be intact, wash it by hand in warm soapy water to remove any remaining food residue or soap residue. Dry the item thoroughly to prevent water spots or bacterial growth. Check your dishwasher for any signs of clogging or damage, and clean it out according to the manufacturer’s instructions.
