Yes, SIGG bottles unique organic liner will ensure that there is absolutely no migration of either the liner or the aluminium of the bottle seeping into your beverage. SIGG bottles have been independently and extensively tested in Europe, USA and Australia to ensure 0.0% leaching! SIGG has been manufacturing and perfecting metal beverage bottles for over 100 years and produce products of the highest quality and safety standards in the world.

What If I Scraped Or Chipped Off My Liner? Some of our customers have inadvertently scraped or chipped off their liner exposing some of the aluminum and have asked if the bottle was still safe to drink beverages from. Research shows it's nearly impossible for the body to absorb enough aluminum to cause Alzheimer's. A study in May 2007 Journal of Alzheimer's Disease found that you would have to absorb MORE than 1,000 milligrams of aluminum each day to increase your risk of dementia. That's the equivalent of drinking 1,000 cups of tea (one of the HIGHEST sources of aluminum in the human diet). Since the average person is exposed to less than 10 milligrams a day, you are pretty much safe.

But Doesn't Aluminum Cause Alzheimers? No, it’s a myth that has persisted since 1965, when researchers found that exposing rabbits’ brains to aluminum caused nerve cell damage similar to Alzheimer’s. Many over−the−counter medicines contain aluminum. One antacid tablet can contain 50 milligrams of aluminum and a buffered aspirin tablet may contain about 10 to 20 milligrams of Aluminum. A SIGG bottle, even though is made of aluminum, will not leach any aluminum whatsoever into your drink because of our liner.

No, the inner coating is highly elastic. Dents cannot crack the coating and the SIGG bottle remains perfectly usable. Because the liner is virtually baked into the inner walls of the bottle, it will not flake or chip even if dented on the outside.

We recommend rinsing your SIGG thoroughly under the faucet with warm, soapy water at the end of every day and letting it air dry with the top off. When more thorough cleaning is required, you can use baking soda and vinegar. For tough jobs, pick up some SIGG cleaning tablets and a SIGG brush. Do not use a hard bristled brush to clean the interior of your SIGG bottle as this will damage the liner.

DISHWASHER? We do not recommend using the dishwasher to wash your SIGG bottles. The Dishwasher is too harsh and will damage the non-toxic food-based paint on your bottle, so if the design is important to you and you don't want the paint to fade or maybe chip off - avoid the dishwasher. Also, the opening of the SIGG bottle is small - and a dishwasher cannot shoot the water all the way up into the bottle to clean it thoroughly. Some tops have rubber gaskets on them - which will deteriorate in a dishwasher and cause your bottle to leak.

DO NOT USE METAL TO PICK OR SCRAPE AT THREADS, DO NOT USE STEEL WOOL, DO NOT USE HARSH ABRASIVES.

Yes, of course. All SIGG bottle tops provide a 100% seal and cannot leak.

No. Strong heat can damage the outer coating.

SIGG has two liners, one bronze coloured one that was on all bottles before August 2008 and the new dull pale yellow coloured “EcoCare” liner that is on all bottles manufactured after August 2008. Swiss Imports New Zealand launched SIGG in New Zealand in March 2009 with the 2009 EcoCare liner range.

About the EcoCare Liner (Post August 2008)
The new SIGG EcoCare liner is a powder-based, co−polyester that has been thoroughly tested and certified to be 100% free of BPA, phthalates, BADGE, BFDGE and NOGE. SIGG EcoCare liner is also environmentally friendly as its application generates virtually no waste and utilizes no organic solvents or VOCs. Our new bottle liner is not only a technological advance; it´s a major step forward in SIGG´s journey towards sustainability. SIGG were the first aluminum reusable water bottle company in the world to phase out BPA from our entire product line.

About the Former Liner (Pre August 2008)
SIGG utilized a water-based epoxy liner that contained a trace amount of BPA. These bottles were thoroughly and regularly tested in the U.S. and Switzerland and all tests revealed absolutely no migration or leaching of BPA or any other substance from the former protective liner.

Not necessarily, in our opinion. Independent testing has shown that since some stainless steel bottles have no protective liner, they can impart a metallic taste because they leach heavy metals such as Chromium, Iron, Nickel and Manganese. These bottles also can be more prone to corrosion.
