That's actually painful to hear, like using a collector's item as a doorstop is wild lol. A polished geode is way more than just a random rock, it takes work to get it like that. Totally get why you locked everything up after that.

150 grit did the trick. Smooth finish every time.

Man, it's wild how overthinking things can actually block those happy accidents!

Honestly disagree based on my own place. Washed my windows with a pure system last week and they still got dusty streaks after they dried. The problem is our wind just blows new dirt onto any damp surface before it can fully dry.
