When I got myself set up for DIY I didn't buy new bottles in a small/sample size because I had a lot from commercial samples I didn't like or used up. It is looking like that was a mistake. After two hot water and dish soap washes and a lot of rinsing I am still getting strong smells of the original flavors. I'm assuming that this means that I'm probably going to be able to taste the original flavors, and even if they are sort of similar that would make it hard to tell if I like what I'm trying to make.
So, does anyone have a sure fire way to clean these out, or do I need to order new bottles for my test batches?
