Can we simply toss them into the dishwasher without worry or should we take extra precautions to protect our investment? Let’s delve into this topic further and uncover some fresh insights on caring for your beloved Stanley Cup – both inside and outside the kitchen.

Understanding the Material of Stanley Cups

Stanley cups are known for their durability and functionality, and they are made from various materials. The main recyclable material used in Stanley cups is stainless steel, specifically 18/8 stainless steel, also known as 304 stainless steel, which is composed of primary materials iron ore, chromium, silicon, nickel, carbon, nitrogen, and manganese. This material is 100% recyclable, making it an environmentally friendly choice.

Variations in Construction

Stanley cups are designed to be insulated, and a small circular cap on the bottom exterior of the cup contains a material with lead.

This lead is used as part of the tumbler’s vacuum insulation and is covered by a stainless steel layer, making it inaccessible to consumers. The lead is enclosed in stainless steel, ensuring that it does not come in contact with the drink inside the cup.

Manufacturer Guidelines and Recommendations

Stanley, a brand known for its drinkware and gear, provides guidelines and recommendations for the proper care and use of their products. Some of these guidelines include:

• Cleaning: After using cleaners, always wash your bottle thoroughly as recommended in the care and use instructions. Stanley recommends consumers regularly clean their cups, formally called “Quenchers” or tumblers, to maintain their quality and performance.
• Dishwasher Safety: The bottom of your Stanley product will indicate if it is dishwasher safe. For these products, it is always recommended to put them on the top rack. Please hand-wash any items that are not dishwasher safe.
• Microwave Safety: Stanley products are not microwave safe, and it is recommended to avoid using them in the microwave.
• Recycling: Stanley is committed to ethical manufacturing, reducing their corporate footprint, and living by a guarantee that means replacing a single part instead of a whole product whenever possible. The company uses recyclable materials whenever possible in different stages of production, which reduces the production of harmful pollutants and extraction of natural resources.
• Vacuum Insulation Technology: Stanley’s key feature is its vacuum insulation technology, which provides consumers with drinkware that keeps beverages at the ideal temperature. The company uses an industry standard pellet to seal the sealing material, which includes some lead. Once sealed, this area is covered with a durable stainless steel layer, making it inaccessible to consumers.
