Scrubbing power, thorough clean, use for all sizes, handle/wiring bends with too much resistance
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. Read more
