I used to clean every lens with just a microfiber cloth until I ruined a $400 coating

For years I thought a good microfiber cloth was all you needed for lens cleaning. Two years ago a customer brought in a vintage Nikon 50mm f/1.4 with haze and I thought I'd just wipe it down fast. Turns out I dragged a tiny grain of sand across the front element and left a scratch that killed the value. Now I always use a rocket blower first to get big particles off, then a lens brush, then a microfiber with a drop of solution. The extra 30 seconds saves hours of regret. Anyone else learned this the hard way with an expensive piece of glass?

Ruined a $400 coating" - oof, that's a $400 lesson in sand physics.

Wince right along with you, @troy_palmer76. Sand is basically tiny glass shards that find every microscopic gap. I had a buddy who used a pressure washer on his car after a beach trip and blasted the clear coat right off the hood. That coating wasn't cheap either, and he spent the whole summer staring at this cloudy patch every time he walked past it in the driveway. It's wild how something as simple as a little grit can turn a perfect finish into a mess if you're not careful.
