About the brush

[Xiaoxiao]

Hello, everyone. So today when I cleaned the brush. The brush I used for cleaning water bottle. I guess there is a little detergent on the brush. Is it fine to use it tomorrow when the detergent is dry or it will have some harmful residue on/in the brush?

There will be no harmful residue on the brush.
It will be fine to use tomorrow.
