The bottles must not be placed in the microwave, on a hot stove, in a hot oven or in the freezer.

Aluminium is an excellent conductor of heat. This means that the temperature of the liquid is also noticeable on the outside of the drinking bottle. We therefore recommend filling it with water at a maximum temperature of 40°C.

All SIGG drinking bottles have been tested with many different types of drinks, such as acidic drinks, carbonated drinks, milk, alcohol, apple and lemon juice, etc. However, we do not recommend leaving drinks with natural fermentation processes, such as apple juice or milk, in the bottle for long periods of time. This natural process can encourage bacterial growth and create gases and strong odors that are difficult to eliminate.

All SIGG caps are waterproof. But caps and seals are also subject to normal wear and tear from intensive use. We recommend not washing the bottle cap in the dishwasher, but removing it, rinsing it with hot water and letting it air dry. It is often also helpful to replace the bottle seal where possible. This is available as a spare part from retailers and in our web shop.

For aluminum bottles: Use cleaning tablets or mild detergent; do not put in the dishwasher.

For glass bottles: Clean by hand only, no chlorine or bleach, use soft cloths/sponges.

For plastics ( e.g., Tritan, polypropylene): Although partially dishwasher safe, hand washing with a mild detergent is recommended to avoid damaging printing ink, etc.
