Lunch & Bento Boxes

Please refer to the packaging or base of the product to determine if the product can be placed in the microwave. Please ensure both the base and lid are microwave safe. If the lid is microwavable, please ensure you remove and place loosely on top prior to microwaving.

You can find additional information under the Care and Use section of the FAQ’s.

Please check for a symbol on the packaging or base of your Smash product to determine if it is freezer safe.

If the product is freezer safe, we recommend only filling to ¾ capacity, to ensure there is room for the frozen contents to expand.

We don’t recommend freezing stainless steel or glass bottles, although you can certainly fill them with ice cubes to keep your water extra cold.

You can find additional information under the Care and Use section of the FAQ’s.

Whilst some Smash products are considered top rack dishwasher safe, this is highly dependent on the material the product is made from.

For product specific information, please refer to the product packaging or the markings on the base of the product to determine if it is top rack dishwasher safe or handwash only. You can find additional information under the Care and Use section of the FAQ’s.

If your product features a printed design, we often recommend hand washing to extend the life of your product. This includes when the product is marked as top rack dishwasher safe.

Although we use high quality food grade stainless steel, it is rust resistant and not necessarily rust proof.   If rust is detected, we recommend using a paste made of baking soda and vinegar on the rust spot – let it sit on the spot for 5-10 minutes and then scrub with a sponge or soft brush.

If the rust persists after trying the above, please contact our customer service team by clicking here.

To avoid mould, please ensure your product is left to thoroughly air dry before reassembling or storing.   We recommend storing drink bottles with the lid removed or flip top left open, to allow air flow and to prevent a moist environment.

If mould is detected on silicone parts, then we recommend the following:

1. Apply white vinegar to the mould area and leave to sit for half an hour or even overnight if it is a dense area.
2. Use a soft cloth to work the vinegar covered mould in a circular motion until it starts to loosen and then wipe clean.
3. If the mould is very stubborn, try a mixture of vinegar and bicarbonate soda to create a paste which can be applied to the mould affected area and left on overnight.   Then use a soft cloth to remove the paste and rinse.
