Hey guys,

I recently noticed my mister bottle is turning the water a bit yellow-ish after sitting there for a day or so. I was wondering what is a safe way to clean the inside of it without harming the frogs since I use this bottle to spray/mist and supply the frog's water bowl as well. I noticed some type of residue stuck to the inside of the bottle that is only visible if you hold it against a light, so how can I wash this in order to keep reusing it. Unless this is normal from treating water, but I dont remember seeing this before.

Thanks
