PRODUCT QUESTIONS

Our products are FDA tested and approved, and all contact surfaces are guaranteed to be safe and BPS/BPA-free. There are seven classes of plastics. Type 7 is the catch-all “other” class. Because our products are made of multiple materials, we are obligated to use the Type 7 code. However, as mentioned previously, any surface that comes into contact with food or beverage does not contain BPS or BPA.

Preheat or precool your vacuum bottle, mug or food jar by filling it with warm or cold tap water. Let stand for five minutes. Empty bottle and immediately fill with your favorite hot or cold beverage. Lastly, secure the stopper and lid as quickly as possible to avoid heat loss.

Our products are FDA approved and all contact surfaces are guaranteed to be safe and BPA-Free. The steel we use is 18/8, or grade 304, otherwise known as food-grade stainless steel. Like all of our products, our stainless steel items must pass rigorous health and safety tests before they are made available to the public.

We do not recommend putting milk or dairy products in our vacuum bottles or food jars for extended periods of time, as bacteria growth can occur at certain temperatures. Fermenting food and beverages may also cause pressure to build up over time.

It is not recommended to use dry ice in a sealed container as the rapid evaporation of the CO2 from solid to gas can produce unwanted pressure within your product. Please proceed carefully at your own risk.

You may use any soft brush to clean your Stanley vacuum bottle or food jar. Please do not use a metal brush, as this could scratch the stainless steel surfaces.

Please check the bottom of your product to see if it is dishwasher safe. If not, we recommend hand washing. Be sure to wash your product before first use.
1) Fill with warm water and mild detergent.
2) Let stand for 5 minutes.
3) Wash with a soft, damp cloth or sponge.
4) Rinse and dry with a clean towel.
Your product may need a deep clean occasionally. For this we recommend letting a mixture of one part baking soda and one part warm water soak for up to an hour. After rinsing out this mixture, clean with mild detergent.

To thoroughly clean under the gasket or seal, we recommend soaking the top of the cup in white vinegar, lemon juice, or a mixture of warm water and baking soda. With some products, the gasket or seal can be carefully removed with a small tool or instrument and soaked separately.

To clean your product, we recommend washing with warm water and a standard, non-abrasive household cleaner. These cleaners can be applied with bristle brushes, sponges or clean cloths. Soaking the product in a mixture of warm water and baking soda might also help. Some customers have reported that a soak in white vinegar or lemon juice also removes stains and smells. After using cleaners, always wash your product thoroughly as recommended in our care and use instructions. Repeat as necessary until stains or smells disappear. A stainless steel cleaner or polish can also be used on stainless steel products.

The bottom of your product will indicate that if it is dishwasher safe. For these products we always recommend that you put them on the top rack. Please hand-wash any items that are not dishwasher safe.

The vast majority of our products are made using stainless steel. Even items where stainless steel is not the main body material there may still be stainless steel in the hinges, handles and other places. As a result, it is not recommended that you put our products in the microwave. Doing so can result in damage to your product and appliance.

Our products are FDA tested and approved and all contact surfaces are guaranteed to be safe to use with food and beverages. The type of outer plastic material we use for our stoppers is BPA-free polypropylene.

We do not recommend putting any of our products in the freezer. Liquids expand as they freeze and your item will not return to its original shape (let’s be honest, most of us don’t). This expansion can result in damage to your product that will affect its functionality, thermals and seals.

Our products are made of high-grade stainless steel and will last a lifetime when properly cared for. If you are noticing corrosion that appears to be rust, it could be free-iron particles, dirt or residue that has contaminated the surface. To remove these particles, a standard, non-abrasive household cleaner can be used to free contaminants from the surface. These cleaners can be applied with bristle brushes, sponges or clean cloths. A stainless steel cleaner or polish can also be used. Soaking the product in a mixture of warm water and baking soda, white vinegar or lemon juice might also help. Repeat as necessary to get the desired result. After using cleaners, always wash your bottle thoroughly as recommended in our care and use instructions.

Prior to 2009 Stanley vacuum insulated products (including bottles and food jars) utilized Char‐Vac® insulation. This insulation technology packed charcoal between the inner and outer steel walls while drawing the vacuum. In 2009 charcoal was removed from all of our products due to its impact on manufacturing and the environment. Since then, higher grade stainless steel along with better design, welding, and vacuum technologies have been implemented to maintain durability and increase thermal properties.

The “patent pending” denotation on some of our products is designed to inform the public that we have filed for patent protection for one or more design or functional aspects of the item that we consider to be an invention. In some cases it can take several years to obtain an actual issued patent, so this denotation puts the public on notice.
