Its so funny how different we all our in making our beloved Tea We like our ice tea unsweetened
Mostly I make sun tea 1gallon glass container filled with filtered water 12 tea bags and sunshine 4-8 hours. When I bring it in and remove the tea bags I leave it on the counter till its cool or room temp before putting it in the fridge. It will last 48 hours easy without getting cloudy. I have also found if I use just off the boil water I only need 8-9 tea bags again if I let it cool on the counter before refrigerating it does not get cloudy.
I have never heard of using baking soda in tea.
