Metal straw FAQs

When Kat founded Kalleco she decided to launch the brand with metal straws. This was because it is a simple change that people can make to their lives which can make a significant impact on the environment. Plastic straws make up 7% of plastic items found in the oceans, so removing any from the eco-system is a big benefit. Since we launched, we get a few recurring questions about our products, so we have decided to do an FAQ about (drum roll)... straws!

Different types of stainless steel metal straws

Why use a straw?

If you have sensitive teeth, a straw can be an absolute godsend. This is particularly the case when you’re having a cold drink or something acidic. Using a straw reduces the contact time with the sensitive bits in your mouth, and reduces the contact time of liquids that are likely to stain. Even if you don't have sensitive teeth but you drink a lot of smoothies or fruit juices, they can erode your enamel when in direct contact with your teeth, a straw will reduce the contact the acids have with your teeth and is often recommended by dentists. For people who wear make-up, it also stops your lipstick smudging.

They’re also hygienic. Straws became popular when people used to share cups at ‘soda fountains’ in the US. Each person having their own straw reduced the spread of communicable diseases, and public health was improved. I’ve written a blog about the reasons for switching to a reusable stainless steel metal straw here.

Why not use plastic straws?

The government has a plan to ban plastic straws between October 2019 and October 2020. Government estimates are that we are using 4.7 million plastic straws in England alone, each year.

As already mentioned, plastic straws make up a large proportion of water that finds its way into our water systems, into rivers, lakes and oceans, as well as leaching into the water table as it is broken down into micro-plastics. The #passonplastic campaign is encouraging people to reduce their plastic use by cutting down on single use plastics and straws are a great place to start. Alternatives are becoming more and more available, be they metal, bamboo, glass or paper, and all of these cause far less environmental impact than plastic straws. Do watch out though - some paper and cardboard products can have plastic linings.

Are metal straws hygienic?

All of our stainless steel metal straws are made from 18/8 food grade stainless steel. This meets all regulatory requirements and is as safe as using your knife and fork! Stainless steel does not rust, and one of the reasons it is so common in kitchenware is because it is not corroded by the acids found in food and drinks. There are no chemicals in the metal which can pass on into your system.

In addition, they are really easy to clean. The surface of a stainless steel product does not have areas for bugs to breed, and when you buy a pack of Kalleco metal straws they come with a free cleaner. This means that you can easily get rid of any food residue, leaving your straw fresh and clean for its next use.

Do stainless steel straws change the taste of your drink?

No, although the sensation of a metal straw in your mouth is a bit different to the plastic that you might be used to! Remember, the advantage of stainless steel is that it has no chemical compounds that can go onto your drink, unlike the BPA, found in plastic, which can leach from your plastic straw. Like with your knife and fork, the stainless steel does not pass on any taste or flavour to the drink, all you are taking in is the goodness that you sip! As with anything new, it can take a little bit of getting used to, but we wouldn’t switch back now!

Are metal straws suitable for children?

Whilst stainless steel metal straws have a big advantage in terms of environmental impact and that they are reusable, the area where they lack compared to plastic straws is that they are not flexible. As a result, if you have a little person who is using a straw, whilst being active, we would recommend a paper straw. Children have a tendency to fall over, and you don’t want that to happen while they have a metal straw in their mouth! When the kids are not active, then that is a call for parents to make for themselves and we would recommend supervision. We have friends whose children use metal straws at the table, but they make sure that they don’t have them on them when they are running around.

How do you clean your metal straws?

Day to day, we rinse our straws under water, wipe them down with a sponge, and then clean from both ends using the cleaning brush that is provided as part of the packet. It’s as simple as that! In addition, all of our straws are dishwasher safe, so you can just chuck them in there! On the go, I usually have a sip of water after a smoothie to rinse any residue before putting them back in their handy pouch.

How do you bring back the sparkle?

As with all stainless steel products, over time the metal straws’ shine may start to fade and tarnish. To bring back their glisten, put some white vinegar on a cloth and rub along the length of the straw until shiny, then wash as normal. For harder to remove discolouration, you can soak in vinegar all night before wiping and washing as normal.

Which style of metal straws should I get?

You don’t have to choose! We have a customised pack available, where you can mix and match our full range!

Our range of stainless steel metal straws

I’m personally a big fan of the smoothie straws, as I like to have thick shakes and smoothies, and find that the extra diameter can help me to suck up lumps and thick drinks more easily. The regular diameter ones are also good for smoothies though and Kat always uses a regular straight straw for her morning shake. Our curved straws provide more of a classic straw aesthetic, and look gorgeous in cocktails. Even with the bend, they are still as easy to clean as the others (the straw cleaner bends around the corner). Finally, we have our gorgeous rainbow straws, which are perfect for when you are feeling shiny and fabulous! All of our straws come with a cleaner and in a handy carry pack which makes taking them around with you super easy.


If you have any other questions about our stainless steel metal straws, or about any of our other products, feel free to contact us either by commenting on this blog, or drop us an email. Small changes can make a big difference, so if you are thinking about making the switch from plastic straws then there is no time like the present!
