How long does my vacuum flask keep the heat?

How long your drink will keep its temperature in your vacuum flask will depend not only on what kind of flask you are using, but also the size of it and what temperature it has when filling up the flask. Below you can see three different graphs showing how the temperature will change during a period of 24 hours in our C&H Vacuum flasks, Make sure the beverage is 97° C when first pouring it into the flask. Notice how it differs when comparing a 0.5 liter flask with a 0.75 and a 1 liter flask. 

Remember to fill up your vacuum flask with warm water before using it and let it stand for five minutes so that it get warm before pouring in your drink.

How do I clean my vacuum bottles?

Clean it after every use, using a dish brush and washing up liquid. You can remove the seals in the stopper and clean them separately. If the product is difficult to get clean, use dishwasher detergent or bicarbonate/baking soda together with water and let it soak overnight.

Please, do not wash your vacuum flask in the dishwasher as the coating could become discolored. Also as the small hole doesnt let enough water into the flask to clean it properly.
