What kind of stainless steel do you use?

All of the stainless steel used in our products is high quality, food safe, corrosion resistant and independently tested for lead free. 

Our stainless steel bentos are made in India with high-quality, food-grade stainless steel 202. 

All our other stainless steel products including the snack containers with non-toxic 100% silicone lids are made in China of high-quality, food-grade stainless steel 304. It is also called 18/8 stainless steel. 

What kind of bamboo do you use?

We use chemical-free, naturally grown bamboo in all our cutting boards, unpaper kitchen towels, straws, cutlery, and vegetable cleaning brushes. We only use untreated bamboo with no chemicals added in these products. 

Our bamboo cutting boards come coated with vegetable oil to keep the longevity and durability of the product. 

All our bamboo products are made in China with tested and certified bamboo manufacturers. 

What kind of silicone do you use in your snack containers?

Our snack containers use a pure food-grade silicone that meets FDA and NSF testing requirements. It's non-stick, flexible and easy to clean, and doesn't dry out and crack with use! Our silicone lids are dishwasher safe and oven safe up to 400 degrees Fahrenheit (204 degrees Celcius).

The silicone lids are also freezer safe, but beware because it's risky to freeze in our steel containers. Liquids swell when frozen and if the steel container is overfilled the freezing will split the steel.

Why are silicone lids better than plastic?

From a human and environmental health perspective, we believe that silicone is currently the best material available for snap-on, leak-proof food container lids because it's long-lasting and free of estrogen-mimicking chemicals commonly found in plastics, like bisphenol-A (BPA).

Silicone is a synthetic polymer made from the Earth's element silicon, which is the second most abundant element in the earth's crust and makes up about 27% of the average rock. When mixed with oxygen, silicon becomes silica and is present in nature as sand and quartz that are commonly used in making glass.

Non-toxic and rubber-like, the silicone material used in our products is much more durable and longer lasting than plastic and it does not contain petroleum. Silicone resists degradation resulting from prolonged use as well as exposure to extreme temperatures and can safely be put in the dishwasher or the oven. Although silicone is not biodegradeable, scientists believe the material is not hazardous to the environment nor toxic to aquatic or soil organisms.


Washing Instructions

Please wash all products with warm soapy water prior to first use. 

How do I wash my stainless steel food containers?

With hot soapy water and detergent - or in the dishwasher! Do not use bleach, harsh chemicals, abrasive cleansers or pads. With proper care and cleaning, your stainless steel lunchboxes may be used for years and years to come.

Does stainless steel corrode or stain?

Stainless steel is a material that is used extensively in the kitchen due to its general resilience against things like heat and corrosion, along with a pretty good level of stain resistance.

Usually, the chromium within stainless steel reacts to oxygen in the air and forms a protective film, preventing problems like rust and reducing the risk of permanent marks. With gentle care and regular cleaning, stainless steel will often last for many years and resist developing rust or stains!

However, while stainless steel is highly resistant to corrosion, it's not completely impervious.

If it’s treated with harsh chemicals, like bleach, or its surface is coated with grease or dirt and not regularly cleaned, the stainless steel is more vulnerable to corrosion and wear. Regular gentle cleaning is required to preserve the appearance and integrity of its surface. In fact, stainless steel actually thrives with frequent cleaning, and, unlike some other materials, it is impossible to "wear out" stainless steel by excessive cleaning.

Cleaning Tips & Tricks for Stainless Steel

  • Wash by hand or in the dishwasher with detergent will clean stainless steel safely and thoroughly. Follow with a hot water rinse.
  • To remove food stuck to your lunchbox:
      • Soak the container in warm soapy water and then clean with hot soapy sponge.
      • For more stubborn cases, a Nylon non-abrasive pad with detergent should be adequate for dealing with most deposits. 
      • Another gentle but tough approach to removing deposits and stains is to use a baking soda paste. Simply mix a tablespoon of soda with a little water into a thick paste. Coat the problem area and leave for half an hour. Then rub with a damp cloth, rinse and dry.
  • Please note: Water with a high mineral content tends to leave water spots, so in this case, it is recommended you wipe the surface completely dry with a clean, dry cloth.

No Bleach... and Other No-nos

  • Bleach will stain and damage stainless steel, do not use cleaning sprays or solutions that contain bleach.
  • Never use steel wool or steel brushes. They will scratch the surface of your stainless steel and make it more susceptible to rusting and staining.
  • Abrasive cleaners will scratch the surface and should always be avoided.
  • Dirty water and cleaning solutions can leave a residue that can stain and damage the surface, so don’t forget to rinse and dry.
  • Long-term exposure to table salt and salt and vinegar mixes can damage stainless steel. 
  • In order to reduce chance of staining, do not allow the following acidic food items to remain on stainless steel surfaces for hours: ketchup, mustard, mayonnaise, lemon juice, vinegar, salt, and salad dressing. 

Are the silicone lids dishwasher safe?

The silicone lids used in our snack containers are dishwasher safe. They can also be hand washed. Avoid harsh chemicals like bleach.

In case of food odors, wash the lids with a paste made from baking soda and water. Simply mix a tablespoon of soda with a little water into a thick paste. Coat the problem area and leave for half an hour. Then rub with a damp cloth, rinse and dry. 

How do I wash the bags?

All of our grocery and produce bags are made from 100% natural cotton. Machine wash cold. Tumble dry medium. Hand washing and air drying are OK, too. Dyes are color fast. However, repeated washing will gradually soften the colors. 

How do I wash bamboo utensils?

Wash in hot soapy water. Towel dry. Bamboo is not dishwasher safe. Do not soak.


Hot or Cold

Are your lunchboxes insulated?

Our lunch boxes are made with the traditional single layer of stainless steel and do not function as a thermos. Ecozoi lunch boxes will keep food warm for about an hour. Remember the stainless steel container will take on the temperature of your food, so if you put hot scrambled eggs in your lunch box, it will become hot as well! 

ECO TIP: Here are a couple of strategies to keeping food cold – pack a stainless steel water bottle with ice and top off with water to use as an icepack inside your lunch bag. Alternately, we suggest wrapping an icepack in one of our ECOnapkins and adding it to your lunch! This will keep the container cool and catch any condensation from the icepack.   

Can I warm food in Ecozoi lunch boxes?

Yes, but be careful! Stainless steel is oven safe and foods can be warmed in our lunch boxes up to about 350 degrees Fahrenheit. A toaster oven also works great! Use over a camp stove is also acceptable. (Please note: Heating over a campfire might work if done carefully, but the fire will blacken the bottom and it's harder to control the heat, so the container could get damaged and we don't recommend it.) Keep in mind that metal is conductive and will get hot. We recommend using a pot-gripper to lift your hot lunch box.

However, please make sure you remove the silicone seal from the lunch box lid before using them in the oven.  

Stainless steel is not for use in the microwave. Our containers are not recommended for freezing foods either since freezing swells liquids and the expansion will split the steel.


Adjusting Clips

How do I make clips tighter or looser?

The clips on our stainless steel lunch boxes can be adjusted! Some people like a hard tight snap when they clip shut their Ecozoi lunch box. But little people often like a less tight clip, so it's easier to open and close our lunch boxes all by themselves.  

Regardless of how tight the clip is, we recommend pushing open the clips of our stainless steel food containers with your meaty part of your thumb. Learning to open/close a Tupperware container may take a bit of practice and, in the case of small children, some basic instruction. The same is true with our ECOlunchboxes. Typically, children and adults fumble a bit with the clips the first two or three times and then the opening/closing becomes very intuitive and easy!
