Using a funnel, add the gin (or vodka) and essential oils to a dark amber or dark cobalt blue spray bottle. (Dark coloured bottles will protect your essential oils from UV light).We used a clear Cortas rose water bottle in this post to feature the finished product, but your glass cleaner will fare better stored in dark glass.Be sure to add the vodka and essential oils to the gin before you add the vinegar so that the essential oils can disperse more readily.
Remove the funnel and shake well. Then, use the funnel again to add the vinegar, and shake vigorously once again.
Remember to give your lavender lemon glass cleaner a good shake before each use. Otherwise, the essential oils tend to sit near the top of the bottle.
