Hey Opinionated, how do you wash your bottles? You've probably said before... sorry.
I have a TON of used blue Boston bottles and I'd rather clean the old juice out instead of tossing them. That's why I have a ton of them.
Your using the glass boston? I'd just use dawn dish soap and hot water and rinse really well... I scrub using straw cleaners and tiny bottle cleaners I make using wire and pieces of sponge...
its a little more difficult with plastics than it is for glass because plastics hang on to scents and flavors. For new plastic bottles I go an extra step with vodka.. but I've never needed to with glass...
