Review on 🔬 100 Pre-Cleaned Microscope Coverslips by AmScope CS S18 by Kevin Carr

Bought not to use as a microscope coverslip but as a protective cover for a delicate sensor. I'm concerned about their optical transparency. When I received them, I examined them under a 3x magnifying glass. They're pretty dirty. I have cleaned some with soap, water and mechanical cleaning. I washed them well and dried them with a clean towel. That made them clean enough for my purposes. I tried just using rubbing alcohol but it didn't remove all the dirt. They worked fine after I deleted them.
