How to Clean a Thermal Camera’s Germanium Lens

Use a lens tissue with a solvent (a dry lens tissue can scratch optical surfaces). A good solvent to use is a mix of 60% acetone† and 40% methanol. Acetone alone dries too quickly to dissolve all of the debris. The methanol slows the evaporation time, and also dissolves debris that acetone alone would not clean.
