Amazer Bottle Brush Cleaner, Water Bottle Brush for Cleaning, Short Handle Bottle Brush Scrub for Water Bottles, Glasswares, Travel Coffee Mugs, 2...

I bought these to clean my hummingbird feeders, and the larger brush works great! But the smaller brush does NOT fit into the feeding ports. I had to buy additional smaller brushes, which is annoying since this was partially marketed as being appropriate for hummingbird feeders!

This two-set of brushes do the job of cleaning out glass pint bottles and narrow neck plastic water bottles. Not sure what the small brushes that store in the handles are for but, I suspect, they are for baby nursing caps. The brushes have somewhat stiff bristles that clean out film and do the job that the dishwasher doesn't.

Great for getting in those tight bottles to clean and scrub. Perfect size. Very handy.

As evident by the fact that I've purchased thus set 4 times, these brushes are my go to for everything! From cleaning the travel coffee mugs and water bottles to the tread on shoes, I use these for everything. The bristles are stiff enough to really clean but soft enough the easily bend... making them great for getting into smaller places. The little brush in the handle is extremely helpful and I love that it's attached so it's always there when I need it but doesn't take up extra space. Nothing stains it so it always looks clean. I start out using them on dishes and then end up grabbing it to clean something else. Once I use it on something not human food related, it becomes the scrubber for that item. They last forever. I've bought so many not because they wear out but because I inevitably find another use for them. I have one for cleaning dirt-related items (like the bottoms of my shoes). I have two for my cat's stuff (one for the water bowls and one for their toys). I have one in the garage for the tires on my car and anything I need to quickly clean out there. I have used them on really nasty stuff and then just throw away because I can't see ever using it again once it touched the icky (yes, I may be a tad OCD about that). They are inexpensive enough that I don't feel bad about doing that from time to time. I just bought two more that way I have a fresh one for my dishes when I end up using the one I have for something other than dishes.
