Flex tanks cleaning

[Jared Retter]

Got me some flex tanks. They say to clean with 2% caustic soda... Will pbw followed by star san work? boy they sure smell like plastic, hope that doesnt carry into wine, didnt think about that part...
Any thoughts from anyone using them? 15 gallon models are the ones I have

I have 4 - 30gal tanks and have been using them for years, no issues with plastic odor, PBW followed by Starsan will work fine. I use the unscented Oxyclean followed by a Kmeta/citric acid rinse.
