So I've noticed my HF beads have always had a little bit of an odor (chemical in nature) if you smell them up close but after recently recharging them and placing them in my wineador, I actually smell it when I open the door. It seems to have gotten worse. They are only about a year or year and a half old. Only distilled water. Just seems odd. I perhaps over saturated some recently. I would hate if they transferred anything to my sticks. Thoughts?
