When it comes to taking care of our dishes, utensils, and cookware, we often rely on the convenience of our trusty dishwashers. But have you ever noticed that small, mysterious symbol on some of your kitchen items? The one that looks like a plate with a line through it? You’re not alone! Many of us have wondered what this symbol means, and why some manufacturers insist on placing it on their products. In this article, we’ll delve into the world of kitchen symbols and uncover the truth behind the “do not” dishwasher symbol.
The Origins of the Symbol
The “do not” dishwasher symbol, also known as the “dishwasher not safe” or “hand wash only” symbol, has been a staple in the kitchen industry for decades. Its origins can be traced back to the early days of dishwasher manufacturing, when consumers were first transitioning from manual washing to machine washing. As dishwashers became more widespread, manufacturers realized that not all materials could withstand the high temperatures, harsh detergents, and intense water jets used in these machines.
To address this issue, the International Organization for Standardization (ISO) developed a standardized set of symbols to indicate whether a product was safe for use in a dishwasher or not. The ISO 7000 standard, published in 1982, includes a range of symbols for kitchen and tableware products, including the now-familiar “do not” dishwasher symbol.
The ISO 7000 Standard: A Breakdown
The ISO 7000 standard is a comprehensive guide to symbols used in the kitchen and tableware industry. This standard covers a wide range of products, from utensils and cookware to dinnerware and glassware. The standard includes over 200 symbols, each with a specific meaning and purpose.
The “do not” dishwasher symbol, denoted by the code “ISO 7000-1334,” is just one of the many symbols included in the standard. This symbol is used to indicate that a product should not be washed in a dishwasher, due to the risk of damage or degradation.
Other Kitchen Symbols You Should Know
While the “do not” dishwasher symbol is perhaps the most recognizable, there are other kitchen symbols you should be aware of:
- The “dishwasher safe” symbol (ISO 7000-1333): This symbol indicates that a product is safe for use in a dishwasher.
- The “microwave safe” symbol (ISO 7000-1335): This symbol indicates that a product is safe for use in a microwave oven.
- The “oven safe” symbol (ISO 7000-1336): This symbol indicates that a product is safe for use in a conventional oven.
What Does the Symbol Really Mean?
So, what exactly does the “do not” dishwasher symbol mean? In simple terms, it means that a product is not designed to withstand the conditions inside a dishwasher. This can be due to various reasons, including:
- Material limitations: Some materials, such as glass, crystal, or certain types of plastic, may be prone to thermal shock, breakage, or warping when exposed to the high temperatures and water jets in a dishwasher.
- Coatings or finishes: Certain coatings or finishes, such as non-stick coatings or decorative glazes, may be damaged or compromised by the harsh detergents and heat used in a dishwasher.
- Design and construction: Some products, such as delicate glassware or intricately designed utensils, may be too fragile or complex to withstand the forces and motions inside a dishwasher.
When you see the “do not” dishwasher symbol, it’s essential to take heed and wash the product by hand. Failure to do so can result in damage, breakage, or even safety hazards.
The Consequences of Ignoring the Symbol
What happens when you ignore the “do not” dishwasher symbol and wash a product in a dishwasher anyway? The consequences can be costly and inconvenient:
- Broken or damaged products: Delicate items can shatter, crack, or warp due to the intense forces and temperatures inside the dishwasher.
- Damage to the dishwasher: Large or heavy items can cause damage to the dishwasher’s interior, racks, or other components.
- Safety hazards: Improperly washed items can lead to safety hazards, such as sharp edges, broken glass, or contaminated food residue.
- Voided warranties: Ignoring the “do not” dishwasher symbol can void the manufacturer’s warranty, leaving you with costly repairs or replacements.
Best Practices for Hand Washing
While it may seem like a hassle, hand washing is a simple and effective way to clean delicate or sensitive products. Here are some best practices to keep in mind:
- Use gentle soap and warm water: Avoid using harsh detergents or abrasive materials that can scratch or damage the product.
- Avoid using abrasive sponges or scrubbers: Opt for soft, lint-free cloths or sponges to clean your products.
- Dry products thoroughly: This will help prevent water spots and bacterial growth.
- Store products properly: Keep your hand-washed products away from direct sunlight, heat sources, and moisture.
Conclusion
The “do not” dishwasher symbol may seem like a small, insignificant mark, but it holds great importance in the world of kitchen and tableware. By understanding the meaning behind this symbol, you can ensure the longevity and safety of your products, while also avoiding costly damages and inconvenient repairs.
Next time you spot the “do not” dishwasher symbol, remember: it’s not just a suggestion – it’s a warning. Take a few extra minutes to hand wash your delicate items, and reap the benefits of a safe, clean, and well-maintained kitchen.
