With durable, double-wall vacuum insulation helps keep your beer, coffee, or other beverage hot or cold for hours and the stainless steel construction is easily washed, either by hand or in the dishwasher.

• Department stores: Many department stores, such as Walmart, Target, and Bed Bath & Beyond, carry Stanley Drinking Cups and have a wide selection of dishwasher-safe options.
• Amazon: You can browse, compare and order a range of Stanley Drinking Cups on Amazon and have it shipped right to your door!
• Other online outlets: Retailers like REI,backcountry.com and Dick's Sporting Goods offer a wide variety of Stanley Drinking Cups and always have a nice selection of dishwasher-safe options.

• Durability: Dishwasher safe materials are designed to hold up to the heat and pressure of the machine, which means they won't chip, crack, or melt if exposed to high temperatures.
• Heat resistance: To be dishwasher safe, materials must be able to withstand temperatures of 149 degrees Fahrenheit or higher.
• Non-porous surface: Non-porous materials won't absorb moisture, so they won't become warped or stained when exposed to the dishwasher’s hot water.
• Non-reactive: Certain metals, like aluminum and silver, can react with the dishwashing detergent if they're not labeled as "dishwasher safe," so it's best to avoid using these materials in the dishwasher.

• Stainless Steel: Stanley Drinking Cups are frequently made with Stainless Steel, which will stand up to repeated use and won’t easily corrode or rust. This makes them an ideal option for using outdoors or at the gym.
• Double-Wall Vacuum Insulation: Many Stanley Drinking Cups feature an insulated design to keep beverages hot for up to 8 hours. The double-wall vacuum insulation acts as a buffer between the hot liquid and the cup, so you can enjoy your beverage no matter where you go.
• Shatter-Proof Construction: If you’re looking for a cup that will stand up to a little ruggedness, a shatter-proof Stanley Drinking Cup is the way to go. Made of an odorless, taste-free plastic, these cups are designed to hold up against accidental dings and drops.
• Easy to Clean: Whether you’re in the middle of the great outdoors or just at the office, it’s easy to clean Stanley Drinking Cups with a quick hot water rinse. Many Stanley models are also dishwasher-safe for easy at-home cleaning.

• Sort Before Loading: When loading Stanley Drinking Cups into the dishwasher, it’s important to group them together by type – stainless steel, porcelain, and melamine. This will help to ensure that they all get the same level of cleaning, as they may require a different amount of heat, water, and detergent.
• Place Gently: Make sure to handle Stanley Drinking Cups gently when placing them in the dishwasher. Also, try to avoid stacking them higher than the top shelf, as the additional weight may cause them to improperly clean or crack.
• Use the Right Detergent: Use a specialized detergent for cleaning Stanley Drinking Cups. This will help to ensure that the dishwasher is able to provide a deeper clean. Avoid using a soap that is overly abrasive, as this can wear away the protective layer of your Stanley Drinking Cups.
• Turn Off Heating Elements: If your dishwasher has heating elements at the base of the dishwasher, make sure to turn them off before running a cycle with Stanley Drinking Cups. The extra heat can cause the cups to become brittle or even melt.
• Regularly Clean Filter: Finally, be sure to clean the dishwasher filter regularly. This will help to ensure that no particles get stuck in the vents and can be transferred back to the drinking cups and cause scratches.

• Check for any specific instructions from Stanley. If Stanley has provided detailed instructions on washing the cups, be sure to adhere to them carefully as this should give a clear indication as to whether the cups can be safely washed in a dishwasher.
• Inspect the material of the cup. Different materials have different requirements for washing – for example, cups with stainless steel inner and outer walls will be much more hardwearing and dishwasher safe than those with a plastic interior.
• Consult the product label or packaging. Products that are specifically labelled as 'dishwasher safe' or come in packaging that states they can be safely washed in a dishwasher are likely to be safe to put in the dishwasher.
• Check the heat recommendation. Some cups will require a lower heat setting or a shorter cycle when washed in a dishwasher. Check the product's instructions or label to ensure that it will be safe when put in a dishwasher with a high heat setting.
• Consider any additional features. If you have a model of Stanley Drinking Cups that have a handle, lids or any other features, you may need to take extra care when washing them in a dishwasher.

• Durable and Heat Resistant Materials: For a product to be dishwasher safe, it needs to be made of materials that are durable and heat-resistant enough to withstand the high temperatures and agitation of a dishwasher. This means plastic items, stainless steel products, or glass products are often the best options for items that need to be cleaned in a dishwasher, as these materials are both heat-resistant and sturdy enough to not be damaged.
• Clear Labeling: Another factor that makes a product dishwasher safe is if the product is clearly labeled as such. Most manufacturers are required by law to clearly label their products, stating if an item is safe for cleaning in the dishwasher. If a product isn’t labeled as dishwasher safe, it’s best to skip the dishwasher and stick to handwashing instead.
• Rust-Resistant Finishes: Products made with rust-resistant finishes or coatings are also a good choice for items that need to be placed in a dishwasher. Many stainless steel items have a rust-resistant finish on them to make sure they can handle the higher temperatures and water of the dishwasher.
• Quality Sealing: If a product has any openings, such as for drinking cups or storage containers, it needs to have a quality sealing on it that won’t be damaged by the heat and water from the dishwasher. Quality sealing will ensure the threads and other openings on the product stay intact and won’t be damaged by the dishwasher.
• Dishwasher-Safe Logo: One of the most reliable ways to determine a product’s dishwasher safety is to look for the “dishwasher safe” symbol or logo. This logo, with a picture of a dishwasher, can be found on items that contain specific materials and coatings.

• Soap and Water: For the simplest and most traditional method, simply washing the cups with some mild soap and warm water is typically effective for removing any grime or residue.
• Baking Soda: Mix a few spoonfuls of baking soda with water, and use a soft brush or sponge to scrub the cups. It’ll be effective for lifting away any heavy buildup.
• Vinegar Solution: Mix vinegar and warm water and use it to clean the cups — it will cut through grease and other buildup.
• Rubbing Alcohol: Soak a rag in rubbing alcohol, and use the rag to clean the outside of the cups. Be sure not to get rubbing alcohol inside the cup!

• Dry thoroughly after cleaning – Make sure you thoroughly dry each cup after washing it in the dishwasher. This will prevent any potential damage or accidental breakages as it gives the cup enough time to cool down evenly.
• Inspect for damage – Perform a quick inspection of each cup after washing. Any dents, chips, or other damage need to be identified and repaired quickly to prolong the life of the cup.
• Store in a safe place – Make sure the cups are stored in a dry place away from heat or direct sunlight. This will help keep the cups in excellent condition for longer.
• Handle with care – Take care to not drop the cups or bang them up against other objects during use or storage. Taking care of your cup will ensure it remains a reliable drinking companion for years to come.

• Drying Temperature - The high heat of a dishwasher can cause the inserts in your Stanley Drinking Cups to warp or melt, leading to sharp and potentially hazardous edges.
• BPA-Lined Materials - If your Stanley Drinking Cups are lined with BPA materials, the extreme temperatures of the dishwasher could cause the material to degrade, leaching plastic and potentially dangerous chemicals into your drinking water.
• Cleaning Solutions - The dishwasher detergent could leave behind residue that could compromise the taste of your beverage, as well as potentially be unhealthy if consumed.
• Poor Cleaning - Lastly, the dishwasher may not reach all of the areas of your drinking cup, leaving behind dirt, grime, and bacteria that could be dangerous to consume.

In most cases, these are dishwasher safe, but check with the manufacturer of the lid to be sure.

The cups are made out of polypropylene, which is safe to put in the top rack of the dishwasher.
