How do you get shiny leaves without chemicals or sprays?

I'm always finding ways to be eco friendly and sustainable, and honestly, sometimes I'm just looking for something easy and budget friendly as well and this hack is all of the above.

I create a lot of planted arrangements that include indoor plants with nice shiny leaves.  And these leaves always have water spots, calcium deposits and fertilizer spots that aren't that pretty.

I looked at that shiny leaf spray at the florist supply store and it weirded me out, plus it smells chemically and apart from being an aerosol, I'm sure it contains some ingredients I don't really want to be spraying around or breathing.

So, I started just wiping leaves down, and found that it helped a little, but most of the calcium deposits stuck around.  And then I remembered my mom telling me about what her mom did, and showed me how I could use milk to wipe down the leaves of our plants and it made them nice and shiny.  And I realized, theres a secret ingredient missing here...

Fat, or oil.

So, I starting dripping a little bit of olive oil on a cloth with water and using that to wipe down shiny leaves, and Voila! Nice and Shiny. Nice and Natural. Organic materials and it doesn't seem to interrupt the off gassing of the leaves, I'm guessing because it's such a small amount and because it's olive oil, something that breaks down naturally.

So, THIS IS MY HACK.  I've shared it with a few florists, and I'm hoping more start avoiding that weird aerosol and start using this natural oil and water method.  Mad props if you have one of those olive oil misters, since that would create tiny droplets on a wet rag, that would work well to not completely saturate leaves.

I promise, more of my natural hacks coming down the sustainable floristry pipeline...
