To help you get the most out of your iglu we’ve popped together some super useful tips and cleaning advice to get you’re iglu looking like new.

12oz Coffee Cup
  • Your iglu uses a vacuum lid that when closed perform best with temperatures under 85-90 degrees. If using a kettle if you can afford to wait a minute or two for boiling water to cool you should be good to go. If you can't we recommend opening the central valve to allow excess pressure to escape.
  • To get the best seal from the lid leave the flip portion open when first placing the lid on as it allows excess pressure within your iglu to escape and create a strong seal. Once on you can close the flip portion.

The central valve / flip section has quite a few handy functions:

  • Straw: If you are a fan of iced tea, coffee and cold drinks it's great for holding straws.
  • Flow Rate: if you're more of a sipper then keeping this section closed drastically reduces the flow rate. Prefer a faster rate open this section and the flow rate increases.
  • Pressure: if you're in a rush and can't wait for boiling water to cool. Leaving this section open allows excess pressure to escape and stops the lid from being forced off.
First Generation 16 & 20oz Coffee Cups
  • Pop your iglu in the bath before its first use. We recommended hand washing to prolong the life of its colour.
  • We recommend allowing boiling water to cool for a couple of minutes and leaving the lid in the open position when first securing it to allow excess pressure to escape before closing.
  • When closing the lid allow a couple of seconds before closing to make sure all contents have returned to the cup. Or once closed check there's no excess liquid within the lid.

As a first step, we always recommend testing your iglu with cold water over your kitchen sink to make sure everything is working as it should for added peace of mind.

Second Generation 16 & 20oz Coffee Cups
  • Give your iglu a handwash with washing up liquid before its first use (both lid and body) .
  • We recommend allowing boiling water to cool for a couple of minutes and leaving the lid in the open position when first securing it to allow excess pressure to escape before closing.
  • When closing the lid allow a couple of seconds before closing to make sure all contents have returned to the cup. Or once closed take a sip to ensure there's no excess liquid within the lid.
  • Our straw lids fit your new coffee cup so if you fancy a change you can purchase a straw lid here.
  • Some contents can build up pressure in your iglu (fizzy / carbonated drinks, milk left for a long period, etc.) so please be careful when removing the lid with these inside as it could cause the lid to pop off.

350ml & 500ml Bottles
  • Pop your iglu in the bath before its first use. We recommended hand washing to prolong the life of its colour.
  • Your iglu is vacuum insulated so is great at keeping both hot and cold contents warm or cold for hours.
  • A great tip for keeping contents warmer for longer is filling it to the brim. Empty space promotes contents losing heat quicker.
  • Some contents can build up pressure in your iglu (fizzy / carbonated drinks, milk left for a long period, boiling water, etc.) so please be careful when removing the lid with these inside as it could cause the lid to pop off. With boiling water, we recommend leaving it to stand for a couple of minutes before securing the lid. This really helps with reducing pressure.

Colourful silicone handles are available for your bottle both on Amazon and the iglu website.

Food Pot
  • Your iglu can be hand washed or is dishwasher safe (pot, band and spoon).
  • Keep contents below the threaded line to prevent spillage when securing the lid.
  • A great tip for keeping contents warmer for longer is filling it to the brim. Empty space promotes contents losing heat quicker.
  • If using boiling water we recommend letting it stand for a minute or two before securing the lid (this helps to prevent the build up of pressure).
  • The heat retention abilities can feel like wizardry but the magic taking place is your iglu is drastically slowing down heat loss rather than stopping it all together. We've found everyone uses their iglu differently but a good tip is if you're prepping your food and planning to eat it for the first time 4-6 hours later we'd recommend heating contents above edible temperature when first filling your iglu.

Feel like a change of colour to mix it up we offer the bands and spoons separately too.

Cleaning Tips

If you need to give your iglu some TLC with a deeper clean. We've popped some quick tips (and a couple of don'ts) below for you.


Baking soda and vinegar...


Remove the lid from your iglu and add one or two teaspoons of baking soda. Then add a generous amount of vinegar. The idea is to make the mixture foam up and clean the inside of your iglu by the action of the baking soda being rapidly agitated against the metal. When finished, rinse the mug well and wash with soap and water. One word of caution: please remember when cleaning with baking soda and vinegar that this combination can build up pressure, so always leave the lid off for safety.


We've had a lot of feedback that baking soda alone works too - so if you don't have any vinegar to hand maybe give this a go first.


There are a couple of cleaning methods you shouldn't try too. We've popped these below as they can be tempting:

  • Please don't bleach your iglus: bleach contains a powerful oxidising agent that compromises the chromium oxide (this is the wizardry that makes your iglu stainless). Over time, this can cause a chemical reaction and oxidation that results in rust.
  • Please don't use metal or wire scrub brushes, using these can create tiny scratches that attract stains and residues. Removing these stains can be very difficult and over time will start to taint the taste of your iglu.

Giving your iglu a regular wash with washing up liquid as well as a deeper clean every now and again with baking soda will help keep your favourites fresh and flavoursome for years to come.


Tackling Mould

Mould is a natural microorganism that is drawn to moist spaces. It’s therefore really important that you stay on top of cleaning, drying and monitoring your water bottle or coffee cup. The drying part can be easily overlooked with many of us cleaning and rinsing our iglu but forgetting to dry it off and leaving it damp.


There are over 100,000 types of mould and one you need to keep an eye on is commonly known as black mould (stachybotrys chartarum) as it’s toxic and you need to take immediate action. Beyond visually seeing mould another tell tale sign of mould is smell.


Below are some preventative tips for tackling mould:

  1. Hand wash daily (or at least after 2-3 uses) and also try to soak once a week. When cleaning and soaking gently remove the silicone seals to ensure you’re cleaning all the hard-to-reach areas.
  2. Wash your lids in the dishwasher if possible
  3. Use a brush to scrub the hard-to-reach areas
  4. Take extra care to clean around the mouthpiece.
  5. White vinegar - studies have shown that white vinegar can effectively kill 82% of mould spores, in addition to viruses and bacteria species. Add a mixture of white vinegar and water to fill up your iglu. Let the solution soak inside your bottle / coffee cup overnight. In the morning, wash your iglu vigorously with soap and warm water. Rinse thoroughly to ensure you get rid of the vinegar taste.
  6. Boiling water - fill your iglu with boiling water (this will help eliminate any odour or mould). After allowing the water to sit for several hours or overnight, wash the inside of your bottle / coffee cup out thoroughly with hot, soapy water.

If you’re unable to rid your lids of mould, you can purchase a replacement lid from the accessories section. We really hope this helps and as with all types of cleaning consistency is super important.
