I like to put lemon or vitamins (those tablets that also create fizzyness) in my water and have been wondering if it is problematic to do so in my aluminium drinking bottle. I wouldn’t normally think so, since soft drinks also often come in aluminium cans, but I’m not sure. Are aluminium salts even unhealthy?
If it’s a water vessel I’d only put water in it. Aluminum cans are lined with a specially designed polymer liner for the particular food or drink in the can. Your water bottle is likely not. Don’t put anything but water in it.
Your aluminum drinking bottle will have a plastic lining to protect it from leeching into things anyway, so it shouldn’t really matter.
You should really get a steel one instead, regardless. The lining could tear, leech aluminum into whatever you put in there (even water over time) and make it unsafe to use.
As others mentioned there’s plastic between the soda and can. You can see it in this NurdRage video. Odds are that your bottle doesn’t have it, so it’s probably a bad idea to store acidic drinks in it. (Including sodas.)
Aluminium salts can be toxic although I’m not sure on how much Al would leak into your drink.
Certain types of beverages can definitely cause some types of cans to erode, yes. You’d have to know whether or not your aluminum bottle has an interior lining or not. There are also different types of linings.
Unfortunately, I only know these things from a friend who works in the canning industry so I can’t speak to them with any degree of detail. But some manufacturers get their beverages tested and then have to can them in certain types of cans for that reason.
