According to the Merriam-Webster dictionary, this definition of steeping is: to soak in a liquid at a temperature under the boiling point (as for softening, bleaching, or extracting an essence). I can see how putting your bottle in hot water could facilitate this process. I'm definitely going to give it a try. I just got a new batch of liquids in the mail yesterday and I'll try one out to start and see how it goes.
