Problems of optical surface degradation became apparent while measurements were being made with a laser. After examination, it was concluded that the defects fell into two categories—those caused by atmospheric dust, and those resulting from the effects of cleaning solvents. A procedure is described which minimizes both of these problems.

Calcite was not used as the example because the necessary physical constants are not available. Sodium carbonate is considered a representative case.
