9-Piece Straw Cleaner Brush Kit - for Stanley Mug 40, 30, 20 oz, (3-Size) Extra Long Pipe Cleaners, Straw Cleaning Brush for Tumbler, Sippy Cup, Bottle and Tube

Great for thoroughly cleaning straws, children’s oral medication syringes, and even for other random items that have unreachable crevices if you kind of bend and twist them to do what you need them to do (They aren’t *meant* for that though, so I can’t say it won’t age them more quickly or that the bristles won’t start coming out of the wiring they’re used that way). I’ve used these a handful of times for some odd thing I need to clean. For example I’m able to use a bent one to scrub out our baby bottle sterilizer’s water reservoir that no other brush can properly clean. (If the brush would’ve been unusable after that, I would have still been happy with the product because it doesn’t advertise that potential use so I knew that it could ruin it. And it still would’ve been worth losing one because they’re very reasonably priced, and I don’t clean that item often, but when it does need to be cleaned, I value anything that can clean it.) The bristles in general are sturdy and firm enough to truly scrub rather than just slide across surfaces. As I said, the wiring will bend with too much resistance so for that I give the overall sturdiness a 4/5 (solely for the super-critics/if you’re for some reason expecting the sturdiness and durability of a thick, heavy-plastic lined straw brush). You are getting exactly what is advertised and a bit better. You’re getting a great deal for the overall high quality of these brushes. In my opinion, for what I’ve been able to finally scrub clean with these, the bend-ability is more of a positive and makes for a more versatile cleaning tool. I clean the brushes themselves with soap and water after use on anything moderately soiled, then I’ll either pat dry with a clean towel or set them out on a drying mat. On occasion I have put them in the dishwasher for sterilization, and they hold up well. I store them upright in a tall cup under my sink, bristles up.

If you have pet fountains, this is a must have to keep them safe, clean and maximize the effectiveness of said pet fountains. If you get a pet fountain get this product too. You'll be happy you did when filters changing time arrives. I use these to keep 3 pet rescue fountains out of the box original purchase clean, safe and efficient for my furrbabies.

These brushes are super useful and I use them all the time. The different sizes fit everything from Stanley tumbler straws to other silicone straws, which makes cleaning really easy. They work well at removing buildup and the extra-long brushes reach all the way through larger straws. They also feel sturdy and hold up nicely with regular use. Only downside is I go through them faster than expected because my cat keeps stealing them to play with! Overall, a practical set that does exactly what it’s supposed to. Great to have if you use reusable straws or bottles regularly.

They cleaned the bottle mostly, did not do a perfect job like I was hoping. I still will keep using them.

This is a great deal as it includes several sizes of brushes. I plan to use them not only for straws, but also for cleaning the tubes on my animal water fountains. I also have more than one size straw to clean, so this worked out perfectly for me! Delivery was super fast, too!

Does the job

I love these tools they come in handy for cleaning things out especially the small parts on my pet fountain that I have even though it's stainless steel it gets into the tubes and stuff and cleans it well

Perfect. Doesn't rust. Love different sizes so great for various straws and sip cups.

Great service. Great product. Great prices. AND fun.
