Chart Cleaning and Storage
Product Introduction

All glass and plastic charts and scales may be cleaned with isopropol alcohol to dissolve and remove oil, grease and dirt without discoloring or affecting the optical focal plane surface of the charts and scales. Soap and water may also be used with fair results when there is no oil or grease. Always be sure to use a soft cotton cloth when cleaning.

It is recommended to store our products in the polyethylene bag in which it was shipped. Store the charts and scales where the temperatures will not exceed 90 degrees F. With proper care in cleaning and storing as recommended above, our products should last indefinitely.

  • Avoid the use of colored window cleaners, acetone, lacquer thinners, etc., as they will affect the chart surface.
  • Avoid the use of paper cleaning products as they may scratch or mar the chart surface.
