Q: How do I maximize heat and cooling retention?
A: Before using, pre-fill the flask for approximately 3 minutes. (Use hot water for hot food or cold water for chilled food.) Leave sufficient space in the neck to fit the lid. The top of the flask is wider than most liquid flasks, therefore you should heat your food to the maximum temperature possible in order to have optimal heat retention. Lid must be hand-tightened, but without extra force, as the extreme temperatures will make it more difficult to open. Always test temperature before serving.
Q: How do I clean my Food Flask?
A: Clean with warm water and soap prior to initial use and after every use. Do not completely immerse in water. Dry thoroughly. Always store flask with the lid removed.
Q: How do I remove stains?
A: Fill flask with hot water and add one teaspoon of bicarbonate soda. (Note: do not put the lid on while using this cleaning method.) For best results soak overnight. Always rinse before reuse. To avoid stains and residue, use a solution of vinegar and water with regular cleaning.
Q: Is the Food Flask microwave safe?
A: No, it is made from stainless steel and is not microwave safe.
Q: Is the Food Flask dishwasher safe?
A: No. For best results clean regularly with hot, soapy water.
Q: How do I prevent vacuum forming in my Food Flask?
A: To prevent vacuum forming, make sure the transparent seal is inset the right way. You should be able to see and feel the groove of the seal, with the open groove facing down.
Q: How do I look after my Food Flask?
A: This product is not meant to be used for keeping milk products or baby food warm or cool. Don’t store perishable foods for a prolonged period. Keep out of reach of children when product contains hot liquids, as they can be scalding. Before screwing down the lid make sure that the sealing ring is undamaged and fully fits into its pocket. Transport upright.
