Purtribe Silicone Bottle Brush, Water Bottle Cleaner Brush with Long Handle, Perfect for Cleaning Narrow Neck Containers, Vacuum Sports Bottle, Tumblers, Flask, Glassware (1 Pack, Green)

I got it to clean a gallon jug with a 1 & 3/16 inch opening the length is a bonus. It easily gets all the way to the clean the bottom of a jug and in the opening once a month.

I had a hard time washing my narrow neck aluminum water bottles with my other bristle brush, so I didn't use it as often as I should have. After having mold build up in the bottles numerous times, I needed to find a solution. This brush is much easier to fit in the neck so I use it every few days. I still occasionally have to use the bristle brush to really clean the corners but this keeps the mold from building up in my bottles.

Love that i can stick this in my dishwasher! This really works perfect for those water canteens with a small diameter

Got this for my sports bottle, it's got a small neck so cleaning it was not so easy till I got this.

Great item. It does the job. It reaches even the most difficult spots. So highly recommended.

Definitely good for water glass bottles, but not that great for stainless steel water bottles.

Too stiff to use.

This Purtribe Silicone Bottle Brush, Water Bottle Cleaner Brush with Long Handle, Perfect for Cleaning Narrow Neck Containers, Vacuum Sports Bottle, Tumblers, Flask, Glassware (1 Pack, Charcoal) (Charcoal) has a great long handle, perfect for the tallest water bottles! I do wish the bristles were a little firmer though. They work great for a quick wash on a bottle that is used frequently, but not the greatest for dried on liquids.
