To make sure your travel cup keeps your drink hot for the longest time possible, we recommend first filling it with boiling water to heat the inside, then emptying it out before filling your cup with a hot drink.
Please note that your drink will only stay hot relative to the temperature of the drink when it was first poured in. Whilst the lids will protect against most spills, the travel cups are not leakproof and if knocked over or placed in a bag whilst full, you do risk some drink spilling out of the drinking hole.
To Clean: use hot soapy water to clean after each use, do not leave the cup to soak for a long period of time as this will lead to paint damage and can cause the vacuum to become ineffective. Not suitable for dishwashers.
