Cleaning Your Hydro Flask
Some days it can take me an hour or two before I finish my tea, and then I often fail to rinse out the Hydro Flask until I get home at the end of the day, at least eight hours later, sometimes longer.
After a few months of nearly daily use my Hydro Flask was starting to look pretty stained inside and no amount of dish soap, water, and brushing seemed to make a difference. After a little research I tried generic denture tablets. I dropped a whole tablet in the bottom of the empty Hydro Flask, filled the flask up with hot water, and let it sit over night. The next morning I scrubbed the inside of the flask with a brush.
The first tab tablet made a major difference but did not remove all the discoloration. The next night I used two denture tablets and by the next morning nearly all the stain was gone. The third night I used one more tablet, allowed the flask to soak all night, and then brushed and rinsed in the morning. My Hydro Flask looked as good as new on the inside. Now I am using a denture tablet once a week, allowing the flask to soak all night, and brushing and rinsing the next morning.
