For safety and hygiene please ensure that your Thermos product is cleaned with warm water and washing-up liquid prior to initial use.

Never use a microwave or conventional oven to pre-heat your product. If your product has not been used for some time, rinse with warm water to remove any residual odours. Do not immerse in water. Store with the stopper off. For difficult stains put a teaspoon of bicarbonate of soda in hot water with the stopper off. Can be soaked overnight. DO NOT overfill your product. Leave sufficient space in the neck to fit the stopper. After filling, always ensure that both the outside cup and stopper are tightly closed.
