I like to reuse glass bottles and jars in my kitchen in order to create less waste. Recently, I bought a large quantity of olive oil which I would like to use by pouring some of it in an empty 500ml vodka bottle:
I have a few concerns, however, since the oil I bought came in a dark glass container which I can only assume is there to protect it from light. I also wonder if it would be fine to simply top off the oil in the bottle once it gets low or if I should clean the bottle every time to ensure it remains safe. Basically, how can I do this safely?
