How to safely reuse glass bottles to store oils 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?
Yes, it is safe.

Just wash the bottle with dish soap and hot water.

Unless you do not use the oil in the new bottle frequently, degradation from light should not be an issue; you could store that bottle in a cupboard when not in use (or get a dark glass booze bottle)

Personally, I would try to use a small bottle than a 750ml bottle.
