This is super not only for bottles but also for getting into weird spots on cups and containers. Works well.
I purchased this bar hoping that it could replace the bottles of dish soap that I have been using. The soap bar is nice and bubbly and gets things really clean. You do need to make sure to rinse it well or you can have some cloudiness, but that was just me hurrying. The brushes are able to get tough spots that I'm not able to reach in my canning jars and on pots/pans. I will absolutely purchase again! I would recommend asking those around you if they would be interested and making a group order. I ordered 5 bars and two brushes and was able to save on shipping costs and the waste it produces, plus encourage others to try the product as well. Love this!
The bottle brush works very well! I am still getting used to it because it's a little firmer than other sponges but it cleans bottles really well.
