Here it is: Are Starbucks Cups Dishwasher Safe? - Know This, Before Buying !

Since the cups are made of paper and have printed designs, the intense heat and drying cycle of a dishwasher can cause the paper to tear, the printed designs to fade, and even lead to cups leaking.

We suggest hand washing all Starbucks cups with soap and warm water after use.

• Stainless steel: It is the most durable material used for dishes and survives in high temperatures and pressure of the dishwasher.
• Porcelain: It is less expensive than some other materials and is also quite durable.
• Glass: Glass dishes are a great choice for compactability as they stack neatly in the dishwasher. They can also withstand very high temperatures and are easy to clean.

• Ceramic: ceramic cups are designed to be both microwave- and dishwasher-safe, withstanding temperatures up to 176°F.
• Double-Walled Glass: double-walled glass mugs not only look nice, they’re also both microwave- and dishwasher-safe, withstanding temperatures up to 250°F.
• Bamboo: bamboo cups are not only sustainable and lightweight, but are also dishwasher-safe with temperatures up to 176°F.
• Acrylic: Great for cold drinks, our acrylic cups are also dishwasher-safe with temperatures up to 150°F.
• Food-Grade Silicone: Not only are our silicone cups shatter-proof and stylish, they’re also dishwasher-safe with temperatures up to 176°F.

• Read the label. Many Starbucks cups will have a label that indicates that it is “dishwasher safe.”
• Examine your cup for any damages. Look around the seal and edge of the lid to make sure that there is no tearing or cracking. Heat can be damaging, so inspect your cup carefully before placing it in the dishwasher.
• Check the material and construction of your cup. If your cup is made of glass or any other heat and friction-resistant material, it can probably go through a dishwasher cycle safely.
• Take extra precautions with vinyl printing. Insulated cups with vinyl printed logos can be potentially damaged in the dishwasher due to heat and scrubbing. If your cup has a printed logo, you might want to hand wash it with a gentle soap instead.

• Materials - For an item to be able to safely withstand the temperatures and detergents used in a dishwasher, it must be made from a material that is durable and can withstand the heat and moisture. Good examples are stainless steel, plastic, and ceramic.
• Size - The size and shape of a product also makes a difference, as larger, more intricate items can move around during the washing cycle and get caught on other items, damaging them or the dishwasher itself.
• Hardware - If a product has any hardware or moving parts attached, such as a handle or a knob, then these need to be able to resist the moisture and heat of the dishwasher. Parts made of plastic or certain types of metal are particularly prone to damage, so it is important to choose an item that features hardware built to withstand this environment.
• Design - Even if a product is made of an appropriate material and features the right hardware, it is still important to factor in the design of the item. Some items with intricate designs, such as intricate patterns or sculptures, may be too detailed to survive a dishwasher cycle without damage.
• Certification - Many products are certified as dishwasher safe by their manufacturer, which means that all of the above criteria have been taken into account and the product has been tested for use in a dishwasher. So, if in doubt, look out for the official 'dishwasher safe' stamp of approval!

• Hot Water & Antibacterial Soap: The antibacterial properties of the soap combined with the hot water make this a very effective method of cleaning your cups. Just be sure to scrub the cup with a brush and make sure all surfaces are completely washed before drying.
• Bleaching: For more deep-set stains and germs, bleaching is an effective way to make sure your cups are germ-free. This method is especially effective when combined with boiling water. Just be sure to rinse the cup after the process is complete and dry properly.
• Vinegar: Vinegar is an effective disinfecting agent, killling 99.9% of germs. Simply mix a solution of vinegar and warm water, Add the mixture to your cup, swish it around and rinse off with warm water afterwards.
• Hydrogen Peroxide: Another effective disinfecting agent, hydrogen peroxide can be mixed with warm water and used to rinse your cups. Make sure to rinse the cup after with warm water and then dry properly for a germ-free finish.

• Use the right type of dish soap. Not all dish soaps are created equal. Some may contain chemicals that can damage the cup or may not be strong enough to properly clean it. Be sure to use an approved dishwashing soap that is gentle enough for the cup and strong enough to clean it.
• Make sure the dishwasher is large enough. Starbucks cups are thicker and bigger than regular dishes. To avoid the cup falling out of the dishwasher or becoming blocked, ensure that your dishwasher is large enough.
• Use the proper temperature setting for cleaning. Many dishwashers come with settings for a high-temperature or sanitizing cycle to ensure dishes are thoroughly clean. For Starbucks cups, you should ensure that the high-temperature setting is selected, as anything lower may be too low to properly clean the cups.
• Clean the cup lid separately from the cup. The lid of the cup may be made of a different material and therefore should be cleaned separately to make sure it is properly cleaned and safely reused.
• Be aware of the amount of cups being cleaned. Overloading the dishwasher may block the flow of water in the machine, resulting in an improper cleaning. Be sure to follow the instructions of your dishwasher and only load the recommended amount of items.

So feel free to toss them in with the rest of your dishes and they should come out nice and clean! Be sure to use a gentle cycle and non-abrasive detergent, as harsher detergents may damage the cup's material.
