Review on 🧽 Quickie Bottle Brush: Soft Bristles for Safe Cleaning of Various Bottles - Ideal for Water Bottles, Baby Bottles, and Vases by Scott King

This brush might be harder to fit into narrower bottles that cheaper bottles fit, but it's good. Due to the rigidity of the brush and its bristles, you can easily remove even the most stubborn dirt. Like back when you thought it would be nice to cook instant ramen in a hydroflask, but were too lazy to wash it, and the next day the forgotten piece of noodle dried up and stuck stubbornly to the wall of the hydroflask like steel.
