From time to time, we do get the question of how to clean a test chart.

glass cleanerThetransparent chartsare usually a film or a foil embedded between glass plates. In this case, a simple glass cleaner can do the job. Do not flood the chart with the fluid, and clean the chart on both sides.

brush & soft clothThereflective chartsare made of many different materials, and here the cleaning is a little more difficult because the surface is directly accessible. Dust and other little spots should be cleaned using a brush or a very soft cloth. The surface is sensitive to mechanical harm. So please be very careful when cleaning these charts. Sometimes it is even better to leave the spot on the chart if it is in an area where it does not influence the chart's functionality.
