KeepCup care

The best reusable is the one you use.

Looking after your KeepCup correctly will enhance your enjoyment of our products and extend their life. Choose the product that best suits your use.

On the move

KeepCup products are designed to replace the disposable cup – not a thermos. They have a splash proof, not a leak proof, seal.

KeepCup Brew was created to deepen the sensory experience of the coffee ritual. Glass is tempered, which means it’s tough – but it’s not unbreakable. A drop, or rapid temperature changes may break or shatter the glass. Do not put cold liquids into a hot glass, or place on a wet cold surface when hot.



Be gentle – don’t use abrasive materials or cloths when cleaning.

For everyday use a quick rinse will do it – but we recommend a thorough clean once a week.

Keeping your KeepCup clean makes the coffee experience great for you, and your barista – make sure you hand over a clean cup.

Our lids, plugs, silicone bands and cup components are durable, and designed to be easy to care for. All are dishwasher safe on the top shelf.

Stainless Steel

We recommend washing by hand to keep the surface finish looking great, use after use after use. The vacuum seal is dishwasher safe, however we cannot guarantee the longevity of the surface finish through use in a dishwasher as harsher cleaning chemicals may be used. Finish damage is not covered by the 12 month manufacturing warranty.

As with all stainless-steel items, the KeepCup Thermal should not be placed in the microwave.

Clear plastic

Tritan is dishwasher safe, but grease or oil in the dishwasher may cause clouding.

Clear plastic KeepCup product are made from Tritan. Tritan cannot be heated beyond 100 degrees celsius so we do not advise placing in the microwave.


Cork endures best with gentle handwashing. Removing the cork band risks breaking or cracking as it bumps over the glass indent. Do not remove the band for general cleaning. If you need to remove your cork band, please follow our instructions:

Washing the cork band can cause it to expand and loosen. Just rest it upside down (on the glass tumbler) in a warm place to restore shape.

Caring for cork


KeepCups can withstand microwave heat – with the lid off, always – to 100°C / 212°F degrees.

Exceptions: lid, clear plastic, cork, stainless steel

Extreme heat will warp plastic. If a cup is squashed in the dishwasher or left too long in the microwave, it may change shape.

End of life

Recycling is the last resort. Reduce. Reuse.

The numbers that appear on plastic products refer to the type of plastic material used. Plastics classified as #7 cannot be recycled domestically in most cases. Our clear plastic tritan and PP #7 components can be commercially recycled.

Polypropylene (PP#5) cup, lids and plugs (LDPE #4) can be recycled through most domestic recycling systems. The glass is tempered, so the annealed surface makes it unfit for recycling. No broken glass is recycled.

We are currently validating that cork bands will decompose in household compost at end of life.

Until late 2017, old silicone bands were commercially recycled by our warehouses. Currently in Australia and the UK silicone goes into general waste, as it cannot be recycled, only shredded and repurposed at volume.

In the United States, we engage silicone recycler Eco USA to collect our old bands and convert them into silicone oil, which is then used to create new products.

Stainless steel is the world’s most recycled material, able to be reprocessed infinitely because there is no material degradation during the recovery process. Because of its non-corrosive nature, it is also one of the most durable materials available and should afford you many years of drinking pleasure from your KeepCup.
