Never thought of that tho nothing in the tank has a dusting on it. Ill look into distilled water thank you and give it another good cleaning.

So it's not technically a "dusting" it's more hard water stains.. If you for example use just well or tap water in your misting bottles, you'll notice on glass tanks you start getting almost a white residue on the glass from the minerals in the water. As far as humidifiers depending on where you live you might see a reddish stain develop on the inside of it. That's why they tell you to use the distilled water to avoid it. Once you get that thing clean and swap water you shouldn't see those issues anymore.

Side note just to give you another example, you use that white vinegar to clean your coffee maker too for the same reason.
