+ What are the benefits of glass?

Water tastes better in glass. Glass doesn’t stain, smell, or have a metallic or plastic taste. Not only that, glass is also great for your health. You don’t have to worry about chemicals like BPA, lead, or other unknowns leaching into your liquids.

Still not sold? Think about our environment! Glass is one of the greenest recyclable materials on the planet. By using an Ello reusable bottle, you’re doing your part in reducing waste, not to mention saving money and Earth’s resources by not buying bottled water. Everyone wins!

+ How do I wash my glass or ceramic travel mug?

We advise that you wash your bottle after each use. Placing the bottle in the bottom rack of a dishwasher and the lid in the top rack is the best way to sanitize the bottle. If you do not have a dishwasher, we advise cleaning any buildup in the bottle with a combination of salt and ice. Place both in the bottle and shake vigorously, then rinse thoroughly. We also advise keeping the bottle unsealed when it's not in use. We've found it best to store it with the lid off. This eliminates any moisture buildup.

+ How do I clean my stainless bottle/travel mug?

We recommend hand-washing any stainless products to extend product lifetime. We do not recommend using chemicals on your bottle. This can ruin or rust stainless steel.

Use baking soda for cleaning: For those stubborn spots inside your stainless bottle, mix 2-3 tablespoons of baking soda with a small amount of warm water to form a scrubbing paste. Dip the bristles of your bottle brush in the paste and work paste into affected area on the inside of your flask. Repeat as necessary until stain disappears.

Use white distilled vinegar for cleaning: You can use household white distilled vinegar to help remove any stains or discoloration on the inside of your bottle. We recommend putting ½ cup of vinegar in your bottle, gently swirling the vinegar around to wash any affected areas and let sit for 5 minutes. Rinse thoroughly with warm water and repeat if necessary.

+ Can I place my stainless bottle in the microwave?

Do not put your Ello stainless bottle in the microwave as it will damage your bottle and your microwave. The vacuum seal keeps any liquid you place inside hot for 12 hours, so there’s no need to put it in the microwave.

+ Can I put hot water in my glass water bottle?

No, you cannot put hot water in our glass bottles. Our bottles are constructed of soda lime glass, which is strong but not impervious to rapid temperature changes or impact. Like any glass vessel, it will expand and crack if left in the freezer or hit with boiling water.

+ Can I put my bottle in the freezer?

We do not recommend freezing your bottle or leaving it in a freezing vehicle, as this may cause the bottle to crack.

+ What is Guardian® Technology?

Ello's Guardian® Technology combines High-Temperature Vulcanization and Controlled Post-Curing of our FDA-Food-Grade silicone, plus an FDA and EPA approved antimicrobial additive that inhibits mold and bacteria growth to keep silicone food-contact surfaces cleaner.

Guardian's antimicrobial additive is a specific proprietary solution which is infused into our silicone during the manufacturing process, and has the ability to kill microorganisms or inhibit their growth throughout the useful life of the product. Microorganisms include the likes of microbes, protozoans, bacteria and fungi such as mold and mildew.

By adding Guardian to our products, consumers are benefiting in a number of ways. The antimicrobial protection infused into the product fights against product-damaging microbes that can quicken its deterioration. Stain and odor-causing microbes are also inhibited, and this helps to keep the product stay fresher and cleaner for longer. Importantly, our antimicrobial additive does not wash off or wear away, and will continually fight against potentially harmful bacteria that makes contact with the surface of the product.
