Frequently Asked Questions
We're here for you. You can find answers to frequently asked questions in our FAQ section here . Otherwise, contact us directly via the contact form for further information.

Are SIGG bottles suitable for microwave use?
The bottles must not be placed in the microwave, on a hot stove, in a hot oven or in the freezer.
Can hot water be poured into an aluminum bottle?
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.
What liquids can I store in SIGG drinking bottles?
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.
Are the water bottles leak-proof?
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.
What is the best way to clean aluminum/glass/plastic bottles?
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.

Eco coffee cup for your favourite coffee
Did you know? In addition to filling your reusable coffee cup up at home with your own coffee, many restaurants and cafés offer to fill up your own reusable coffee mug, instead of using disposable cups made of cardboard, plastic and so on. Just ask your favourite café or restaurant! In doing so, you can avoid unnecessary plastic packaging - which is good for the environment. So now you can always have your coffee or tea with you in your SIGG travel mug on the way to work, in the car or on a walk. Soon you won’t be able to live without your SIGG reusable coffee cup to go!
Thermal Insulation to keep your coffee extra hot
Our eco friendly coffee cups come in various designs: Made of double-walled borosilicate glass or double-walled vacuum-insulated 18/8 stainless steel. Both materials are free of harmful substances, environmentally friendly and tasteless, and they also keep your hot drinks warm for hours through double-walled insulation.
More into iced coffee? No problem! Thanks to the insulation, you can keep your iced coffee cooler for longer than with standard disposable coffee cups.
The stainless steel version is particularly robust and can withstand active everyday life as well as outdoor adventures.
What are you waiting for? The SIGG sustainable coffee cup is ready for you.
