Cleaning Water Bottles

Vodka.. I use it to clean out my milk jugs...I feel safer with this rather than bleach or vinegar..I also use it when I re-use my water bottles...

I use a little bit of bleach (take a straw, dip it in the bleach, cap it with my finger) and some hot water, put the lid back on and shake it around. Rinse a few times and then dry in my dishwasher while it's open.
