Metallic Straws: Benefits, Uses & Maintenance

If you’ve ever fished a soggy plastic straw out of a takeaway cup and thought “there has to be a better way,” you’re already halfway to a metal straw. Swapping single-use plastic for one good stainless steel straw is one of the easiest ways to start doing away with disposable — and once it lives in your bag or your kitchen drawer, you barely think about it again.

We’ve used metal straws daily for years, so this is an honest look at what they’re genuinely great at, where they fall short, and how to keep them clean. If a reusable straw is your first eco swap, it’s a satisfying place to learn to sip reusably.

• Best everyday set: a stainless steel straw set with a travel case, silicone tips, and cleaning brushes. Look for 18/8 (304) food-grade steel and a mix of straight and bent straws so they fit both tall tumblers and shorter glasses.
• Best for travel: a collapsible metal straw with a keychain case. It folds down to key size and clips to your bag, so you’re never stuck taking the plastic one.
• Best upgrade: skip loose straws entirely and get an insulated tumbler with a built-in stainless straw (Owala, Simple Modern, and BrüMate all make excellent ones). One purchase covers the cup and the straw — and it’s the one you’ll actually reach for every day.

Metal straw formats, compared

“Metal straw” covers a few different shapes. Here’s how the common formats stack up so you can match one to how you drink:

Format	How it packs	Best for	Watch-outs
Straight	Rigid, full length	Tall tumblers, water bottles, smoothies	Too long for short glasses
Bent	Rigid, angled tip	Everyday cups, sipping while seated	Harder to clean the elbow
Collapsible / telescopic	Folds to key size, keychain case	Travel, commuting, eating out	More parts to rinse; pricier
Tumbler built-in	Lives in the lid	Daily desk & car use	Straw and cup are a set

Why metal straws are worth the switch

They cut a real amount of plastic waste

This is the whole point. One stainless steel straw replaces hundreds of throwaway plastic ones over its life, and that adds up in a system that barely recycles. Globally we produce about 460 million tonnes of plastic a year and recycle only around 9% of it (OECD). Meanwhile, an estimated 8–11 million tonnes of plastic enter the ocean each year (Jambeck et al., via The Conversation). A single straw won’t fix that, but doing away with disposable is built from small, repeatable swaps exactly like this one.

They basically last forever

Unlike plastic that cracks or paper that goes limp, a good stainless steel straw shrugs off daily use for years. Buy once, keep it for the long haul — which makes the few dollars up front some of the easiest money you’ll ever save.

No aftertaste, no leaching

Food-grade stainless steel is non-porous, so it won’t soak up yesterday’s smoothie or hand your iced coffee a plasticky aftertaste. It also doesn’t shed microplastics into your drink the way a softening plastic straw can. For hot or acidic drinks, quality 18/8 steel stays inert and safe.

They’re easy to keep hygienic

Because steel is non-porous, bacteria have nowhere to hide the way they do in a porous material — as long as you run a brush through after use. That’s the trade with any reusable: a few seconds of cleaning in exchange for cutting the waste.

The honest trade-offs

We’d rather you buy the right straw than the wrong one, so here’s where metal isn’t perfect:

• It conducts heat and cold. A metal straw in a hot tea can get warm on the lips; in an icy drink it feels cold. Silicone-tipped straws fix this, and it’s why many people keep metal for cold drinks.
• It’s hard. Metal doesn’t give, so it’s not the best pick for young kids or anyone prone to knocking a straw against their teeth. For them, a soft silicone straw is the safer call.
• The cleaning is on you. No brush, no fun — a straw you can’t clean is a straw you’ll stop using. Buy a set that includes one.
• It carries an upfront footprint. Making a steel straw takes more energy than making a flimsy plastic one. The catch is that plastic is used once; a metal straw is reused hundreds of times, so it pays that footprint back and then keeps going. Longevity is what makes reusables win.

Using and cleaning your metal straws

Using one couldn’t be simpler: drop it in your drink and sip. Match the length to your cup (tall tumblers want a 10.5″ straw; everyday glasses a 8.5″) and you’re set.

Cleaning is where the habit sticks or slips. The reliable routine: rinse right after use, run the included wire brush through with a little dish soap, then let the straw air-dry fully before it goes back in your bag — trapped moisture is what causes funk. Most stainless straws are dishwasher-safe too, though the brush gives a deeper clean. When you’re out, a quick water rinse holds you over until you get home. Our full guide to cleaning reusable straws covers the deep-clean routine, and if cleaning is your sticking point, these easy-to-clean straws are worth a look.

A quick word on what you’re buying: the good stuff is 18/8 or 304 food-grade stainless steel, which resists rust and corrosion. Skip vague “stainless” listings with no grade, and store your straws dry in their case or a drawer between uses.

Frequently asked questions

Are metal straws safe to use?

Yes. Food-grade 18/8 (304) stainless steel is non-toxic, doesn’t leach chemicals, and is non-porous, so it resists bacteria when cleaned. The main caution is with hot drinks, where metal can get warm on the lips — a silicone tip solves that.

How do I clean a reusable metal straw?

Rinse it right after use, run a thin cleaning brush through with dish soap, and let it air-dry completely before storing. Most are also top-rack dishwasher safe.

Do metal straws rust?

Quality 18/8 or 304 stainless steel is corrosion-resistant and won’t rust with normal use. Drying them fully before storage keeps them spotless.

Are metal straws good for hot drinks?

They work, but steel conducts heat, so the straw can feel hot. If you sip hot tea or coffee through a straw often, choose one with a silicone tip or use silicone instead.

How long do metal straws last?

Years — often a lifetime with basic care. That durability is exactly why one metal straw can replace hundreds of disposable plastic ones.

Are metal straws better than plastic?

For waste and durability, clearly. Plastic straws are used once and then persist a long time — NOAA notes they’re often estimated to take up to about 200 years to break down, while stressing real-world timelines are uncertain (NOAA Marine Debris Program). A metal straw is reused for years instead.

The bottom line

Metal straws are the durable, no-nonsense reusable: buy one good food-grade set with a brush and a case, keep it clean, and it’ll outlast a mountain of plastic straws. Keep them for cold drinks, reach for silicone tips if hot sips bother you, and you’ve got a swap that quietly does away with disposable for years. Ready to make it stick? An insulated tumbler with a built-in stainless straw is the easiest way to sip reusably every single day.
