Retractable bottleCleaner / cleaner

Retractable bottleCleaner

The Retractable bottle Cleaner is designed to solve the problem that the existing design is not easy to use. You can just push down the button on the bar, and then the brush would stretch out. Otherwise you can pull up the button to storage up the brush, which is very convenient.
