FAQs

Are these containers lined with Tritan?

No, the Tavva containers are made from uncoated 18/8 food grade stainless steel and are plastic-free. Since stainless steel is non-reactive, containers made from this material don’t leach and don’t have to be lined. Also, the silicone lid is plastic free and very flexible.

Is the silicone lid 100% food grade and totally without any toxic fillers? 

Tavva containers are 100% plastic-free, crafted from high-quality, food-grade stainless steel topped with food-grade silicone lids. Because it does not contain plastic, our product is free of all estrogen-mimicking chemicals, such as bisphenol-A (BPA), phthalates, and bisphenol-S (BPS).

Are the lids easy to open for kids?

Yes, they’re very flexible silicone.

Can you use these to freeze food? 

If you do use them in the freezer, make sure you don’t fill them up to the top, especially when you put liquids in. We all know that liquids expand when they freeze and how an aluminum can will swell up in the freezer. You don’t want that to happen to your nice stainless container, so we recommend leaving about an inch of space for expansion. Also, be careful when taking it out because skin will freeze to frozen metal and that's no fun.

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 container:
      • 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.
