I’ve been using the same stainless steel flask for months, but after seeing some discussions online about lead sealing pellets and BPA in lids, I started questioning are insulated water bottles safe to use for hot acidic drinks like coffee or lemon water. I want to ensure that there is no risk of metallic leaching or chemical off-gassing when the bottle is exposed to extreme temperatures. If anyone has looked into the material safety data sheets for popular brands like Hydro Flask, Stanley, or Yeti, please share whether these are truly a "buy it for life" healthy option.
