CIDIYAUST extra long straw cleaner brush set (9-piece) – 8 inch, 12 inch and 14 inch reusable brushes

The essentials

If you’ve ever tried to clean a cup straw with a short brush, you’ll know the annoying bit: milk residue ends up deeper than the bristles can reach. This CIDIYAUST straw cleaner brush set is built around that problem, with extra-long brushes designed to get further down standard straws and also into the deeper, awkward areas of reusable cups.

The set includes multiple lengths (8 inch, 12 inch and 14 inch), which is handy because straw length isn’t consistent across bottles, sippy cups, tumblers and different drink lids. On paper, it’s the sort of kit you buy once and then keep reaching for, rather than relying on disposable pipe cleaners that you have to replace regularly.

Still, it’s worth keeping expectations realistic: this is a straw brush kit, not a full sterilising system. If you need a more intensive clean routine, you’ll still be using your usual washing/sterilising approach alongside the brushing.

Key points

Multiple brush lengths mean you can match the tool to the straw and the cup you’re dealing with, instead of forcing the wrong size. The 14 inch brush in particular is there for deeper cups and longer straws where short brushes can feel like they’re “scrubbing the wrong end”.

It’s also positioned as a reusable, food-safe option thanks to the nylon bristles paired with a stainless steel handle. If you’re cleaning for everyday use—baby bottles, sippy cups, water bottle straw lids, or reusable drinkware—this kind of tool makes the cleaning step feel less like a chore.

And yes, the flexible, bendable bristles are a practical touch for navigating curved or silicone sections. That matters because straws don’t always stay straight, especially once they’re part of a cup lid or feeder setup.

Where it shines in daily use

This kit is most convincing when you’re dealing with residue that sits below the rim. For example, imagine a tall tumbler with a long straw: you can push the 14 inch brush down, rotate it, and scrub where the milk tends to cling. The longer length is the difference between a quick surface clean and a more thorough pass.

It’s also pitched for baby care items like bottles and sippy cups, where you want to avoid leaving behind any sticky build-up. The bristles are described as soft and effective at removing milk residue and buildup.

Beyond baby drinkware, it’s meant to work as a straw cleaner brush for cups and water bottles, and even reach into small spaces such as hummingbird feeders or narrow-necked bottles. That’s a good sign if you want one brush set that covers more than just one household use.

What you’ll notice about the build

The heads use durable, food-grade PA6 nylon bristles with a stainless steel handle. The material is described as BPA-free, which is the kind of basic reassurance people typically look for when cleaning items that come into contact with food.

The bristles are also described as flexible and bendable, designed to navigate curved and silicone straws. This is useful if you’ve got drinkware where the straw path bends slightly under the lid, because a rigid brush can struggle to follow.

Where it may not feel perfect is if your straws are extremely narrow or have unusual internal shapes. You may still need a bit of patience to find the right brushing angle, even with the flexibility.

Who it suits (and who should think twice)

It makes sense if you regularly clean reusable straws and want multiple sizes rather than buying separate brushes for different cups. It’s also a sensible pick if you’re looking after baby bottles and sippy cups and want a brush that can reach deeper than the typical short options.

It may not be the best match if you only have one cup with a very short, straight straw—then the extra lengths could be more than you need. And if you’re expecting a single brush to replace full sterilisation, you’ll want to keep your cleaning routine consistent, this helps with scrubbing, not with sanitising on its own.

The essentials: what to check before buying

Before you commit, it’s worth checking that the straw lengths you use most are covered by the 8 inch, 12 inch and 14 inch options in the set. If your cups have particularly deep straw wells, the 14 inch brush will be the one you’ll care about most.

Also, if you’re cleaning silicone straws or curved setups, the flexible, bendable bristles are a positive signal—but you’ll still want to ensure you can guide the brush through the straw opening comfortably.

Finally, consider whether you need a multi-length kit or if a single size would do. Kits like this are best value when you use several cup types.

Final verdict

Is it worth it?

Worth considering if you want a reusable straw cleaner kit with multiple lengths, especially the 14 inch option, to tackle deeper straws and stubborn residue in everyday cups and baby drinkware. The food-grade PA6 nylon bristles, stainless steel handle, and BPA-free positioning are all the right basic cues for a cleaning tool that gets used frequently.

Better avoided if you only need a single short brush for one straw type, or if you’re expecting it to fully replace sterilisation. If you’re mainly after a deeper clean step that fits different cups, though, this set is the kind of practical buy that tends to earn its place in the cupboard.
