Our manufacturer is near Shanghai in mainland China. Bottles are shipped into our UK warehouse by seafreight. We have searched all over the World for the highest quality bottle manufacturers and we ensure that our manufacturers continually maintain high standards of quality in production and ensure a safe and compliant working conditions for the employees. The manufacturer works to BS EN ISO9000 quality standards and with regular material conformance tests through external accredited bodies. Our manufacturer maintains BSCI approval which is the control of Environmental compliance, working conditions and Social Compliance and we ensure they maintain high levels of social and ethical responsibility.

We have a small team of dedicated quality personnel based in China who manage our procurement and quality inspections at source and we carry out further inspection and sampling on products in our UK warehouse and record quality performance of all of our products through a closed loop corrective action system.

We have tried to source products in the UK or Europe but have never been able to find a supplier.

Our bottles are all stainless steel made from highest grade 304 or 18/8 stainless steel. This is food grade/surgical grade stainless steel. It is resistant to corrosion and is chemically very inert. It doesn’t impart any nasty odours or tastes into your drinks like other materials can. Most importantly is is 100% BPA free and toxin free. Your drinks will be safe. Many consultant oncologists and specialists in fertility treatment recommend stainless steel bottles because they are toxin free. Bottles do not have any linings or coatings on the inside.

No they are pure 304 grade stainless steel. Aluminium bottles are lined with plastic because aluminium is toxic but stainless steel bottles have no linings. This also means they do not degrade even when they have been dented, battered and bruised, they are still 100% safe and the best material to carry your beverage in.

We strongly recommend you to research before you purchase any plastic bottles claiming to be BPA free (they probably contain BPS or similar and can degrade over time which exacerbates the leaching of chemicals in to your beverage. BPS has been shown to be as harmful as BPA). Similarly, aluminium bottles always have some form of lining or coating in the inside that does degrade over time or can become damaged leaving your beverage in direct contact with aluminium. The newer ranges of aluminium bottles claim to have BPA free or even plastic free coatings but they generally have a form of plastic with BPS or another chemical cocktail to form a barrier against the potentially toxic aluminium. There is plenty of available research on both options. The most inert, least toxic options are glass or stainless steel.

Stainless steel has been trusted by the food and beverage manufacturing industries for many years because it is safe. Stainless steel 304 grade is very inert it does not leach any chemicals.

The plastic caps we use are BPA/BPS free, Non Leaching, toxin free polypropylene. It is a tough plastic, easy to clean but it is more brittle than normal plastic. We do have an all steel cap option. All caps have a food grade silicone sealing ring. Silicone is toxin free.

To ensure your bottles have a long life here are a few tips:

  • Coloured, painted bottles, should be Hand Washed. For daily cleaning, wash bottles in warm soapy water, rinse thoroughly and leave to drain upside down.
  • For more thorough cleaning use a bottle brush and give it a good scrub inside particularly after smoothies and juices.
  • If your bottle begins to smell we recommend either soaking in a sterilising solution like Milton Fluid or using baking powder to neutralise any nasty niffs.
  • Only sports caps are suitable for the dishwasher.
  • The paints and inks we use on our bottles are lead free and toxin free and we endeavour to ensure they are environmentally responsible. These inks are not as impenetratable as solvent heavy inks and, as with anything which is painted, it is possible to scratch or chip the paintwork. To ensure your painted bottle keeps looking tip top please handwash it and if you are concerned about it getting scratched or damaged invest in a protective jacket.

Any cap which is hollow ie the All Steel cap, should not be washed in a dishwasher in case it fills with water. The All Steel Cap should be wiped clean. Any other cap can be placed in the dishwasher. but we strongly advise handwashing them and investing in a tiny brush or pipe cleaner to clean nozzles.

Any unpainted or nude bottles can safely be washed in a dishwasher but we do recommend handwashing painted or coloured bottles just in case it affects the painted finish.

Yes, check the dimensions, but the 500ml,and 800ml straight bottles fit perfectly into standard bike cages. We recommend ‘nude’ bottles for bike cages as painted bottles can easily get scratched by the cage. Alternatively, get a bottle jacket. This will protect your bottle from scratches and stop your bottle rattling in a looser bike cage.

Yes, but the bottle will get very hot so either use a jacket or invest in a vacuum flask.

Yes. Stainless steel 304 grade is resistant to acids. Ensure you wash the bottle thoroughly after sweet  or acidic drinks.

We wouldn’t recommend it but we are aware of many customers who do put the bottles in the freezer. Ensure the bottle is upright and without a cap as the liquid will expand when frozen.

Bottles will last indefinitely as long as you look after them and they don’t suffer excessive wear and tear. Caps should be replaced more frequently for hygiene reasons. We recommend changing your caps every year.

Any painted metal surface can become readily scratched through use or damage. If you are concerned about scratches to paintwork then definitely go for a nude (unpainted) bottle or invest in a jacket. We are sorry but we cannot accept returns or claims on damaged paintwork. Try our new gelly bottoms to protect bottle bases from scratchy surfaces. Please note that painted bottles should be carefully handwashed. Dishwashing painted bottles is not advised because it may lift or damage external paintwork. If this does happen your bottle is still usable.

Our manufacturer works to ISO14001 standards but does not maintain the ISO14001 approval. They do maintain the BSCI approval and are regularly audited.

Our paints and inks are as eco friendly as we can source. We endeavour to use inks which have no toxins and are not damaging to the environment.

Our new QUENCH is great for all ages. Gives you a big slurp of water, it’s quiet, easy to use and leakproof.

Our new QUENCH cap is fantastic.

304 stainless steel is highly rust resistant. If your new bottle appears to have a rust spot is is most likely a laser scorch mark or mark left by the electropolishing process. This discolouration is perfectly harmless. If you have any concerns please try and take a photo of the mark and send it to us.

If you think that rust spots have developed over time inside your bottle please give it a good scrub with a bottle brush and a baking soda solution and see if this helps. If you have any concerns please send us an email to sales@onegreenbottle.com with a photo and we will try to help

We guarantee our products against manufacturing defects for 12 months from date of purchase. Normal wear and tear such as dents and scratches are not covered by the warranty and nor is damage through dropping bottles or caps. We want you to get years of enjoyment from your product but it does need care.

304 or 18/8 grade stainless steel is inert and does not retain flavours or smells. If you have already given it a good scrub with a bottle brush and warm sopay water try mixing a quarter or a cup of vinegar and 4 tablespoons of baking soda in warm water and let it soak overnight. Rinse well with warm soapy water and then with plenty of fresh water and leave upside down to drain.
