How the hell do I clean this thing ?
This water bottle sat in a bag unused for a while and got messed up., I have only ever hand washed it due to stickers on the outside. I've tried soap and water, abenaqui, abrasive scrubbies, baking soda, vinegar, and basically whatever else I could find around the house. As you can see, some of it started to come off after a while but if I keep using the same methods it's going to take DAYS of scrubbing to get this clean. I'm out of ideas. The brand is Bubba if that makes a difference.
